iMac G5 crashes/doesn't wake up
I have an iMac G5 that has a couple strange problems. The problem has been happening ever since I got it from my company about 3 years ago. While it was at the office, I know it had been taken into the shop a number of times for some work (don't know exact what the issue was). I do know that they replaced the motherboard and the hard drive. All that said, here's the issue... If I let it sit idle, the screensaver will kick in and work fine. Eventually, the screen will go black and the system will go to sleep. I can see the power light slowly pulsing. Everything is fine. When I return to the computer, I press the Shift key to wake up the system. It responds by making some 'hey I'm waking up noises' (e.g. hard drive spinning up, perhaps) and the power light stops pulsing. This is where it all goes south. The screen never returns. It stays black. Then, the grand finale... The system fan kicks into very high gear. The system will stay in this state until I press and hold the power button to turn it off. It's a bit of an inconvenience when this happens, but it's not a show-stopper. Or is it? This is what happens next. I press the power button to turn the system back on. It goes through it little screen flashes and wipes and eventually the Apple logo appears. IF the little spinny thing appears under the logo, all is good and the system will boot normally. If it doesn't appear, the next float in this parade is a kernel panic error screen. If I turn it off and back on, it'll probably do it again. If I turn it off and let it sit for at least 15 minutes, it'll probably work normally. Every once in a while, I get the kernel panic screen out of the blue. YouTube and Craigslist seem to give it fits for some reason. Any ideas?

Unfortunately, so were and are the vast majority of G5 iMacs. The symptoms you describe are quite common. I had a 20 first-gen G5 iMac on my workbench last week with the same issues as yours. Most of the problems are related to bad capacitors. Apple and most other electronics manufacturers bought capacitors from an Asian firm in the early 2000s. Turned out the manufacturer used a stolen electrolyte recipe which was missing a key ingredient that stabilized the electrolyte and prevented it from boiling and thus losing the ability to perform its task of holding current values. From a few months after going into service until today, those capacitors have been failing. Sometimes they explode; sometimes they vent out the top or bottom; sometimes they look OK but aren't. Whichever it is, a failing or failed capacitor cannot maintain correct electrical values. When this happens, the dozen or so capacitors in the G5 iMac's power supply and the two dozen or so on the logic board can cause all sorts of symptoms, most of which you now know intimately. Add to this bad capacitor issue poor thermal management. The iMac G5 power supply is at the bottom of the case, where half of the incoming cooling air must pass through it. This results in heated air washing over most of the capacitors on the logic board, further exacerbating the capacitor issue. There are only three temperature sensors on the logic board, which control the optical drive, the hard drive, and the video/cpu/bridge chip fans. (My late-2012 27 iMac has 18 thermal sensors.) The fan that blows incoming cooling air through the copper fins atop the huge heat sink over the bridge, G5 cpu and graphics chip sucks air from the bottom of the case, much like a vacuum cleaner, and thus results in the fan and the cooling fins getting plugged up with dust, lint, etc. As I said, poor thermal management. Fortunately, Apple remedied most of these thermal management issues in the third-gen white iSight G5 iMac, and continues to do so with each new generation of iMac. Another issue that arises in G5 iMacs that have seen plenty of overheating will be familiar to G3 iBook owners: broken solder joints in the BGA (ball grid array) that affixes the video chip to the logic board. Your main problem is a failing logic board. Apple replaced those back in the day, but that program closed years ago. I've even seen capacitor failures on some of those replacement boards. And because G5 iMac logic boards are multi-layer, I've seen non-professional cap replacement attempts permanently damage the boards. This is primarily because Apple began using high-temp unleaded solder on G5 iMac boards, and hand-held soldering tools cannot reach the proper temperatures to desolder and resolder the capacitor legs properly. It is possible to replace the bad caps and reflow the video chip BGA, etc. professionally, but it's not worth the time or expense, in my judgement. Better yet, migrate your data
Re: iMac G5 crashes/doesn't wake up
Wow! Thanks for all the info Jim. Well, at least now I know what the problem is. I've been dealing with this problem since I've had the machine, but never said anything about it. I thought it would be difficult to describe and for someone else to help me diagnose the issue. Turns out my G5 and I are just another statistic. I heard the 'stolen recipe' story when I was trying to figure out why Avaya/Orinoco wireless access points that I was installing for work kept going bad. I found a webpage that told the story and then listed a handful of products that were afflicted with the issue. Just pure coincidence that the wireless access points were on that list. I replaced the bad capacitors and they worked for years. I'm glad you mentioned the multi-layered board. As I was reading your post, I was already thinking hey, I'll just replace the capacitors myself. Now I guess I won't. This machine is not a critical machine in my house. It sits on a small table at the end of my kitchen table. I use it for casual browsing, playing iTunes and looking up recipes (I'm the household chef). Actually, it replaced a Graphite iMac G3. If this G5 machine were to suddenly decide to not work, I also have a 1U tall HP Proliant server mounted under the same kitchen table. The 'server' mostly stays off. I have Ubuntu installed on it for just for messing around. I can always crank that beast up to pull up a recipe. Unfortunately it doesn't have any sound hardware. Wouldn't matter anyway. That thing is so loud I wouldn't be able to hear the music. :) With over 40 computers (PC and Macs) in my house, I'll find something to work. I guess when the iMac G5 finally dies that will be incentive for me get the G5 tower that someone gave me working (think it has a bad processor). Thanks again. Lonnie.

iMac G5 overheating GPU
Hello, I got this late 2005 iMac G5 w/ iSight that suffers from jet engine fans noise (unless it's in Reduced CPU mode). Opened it, got rid of dust and dirt that remained inside. Since then the iMac got better, doesnt go to sleep while running cpu hungry processes, but noticed that its GPU temp is over 80 degreees Celsius (=176 F !) when handling ordinary tasks like web browsing. Do you think it's worth to put some silver thermal paste between GPU and heatsink? I am asking because according to my research these iMacs used to suffer from GPU problem that would require reballing. Fiddling with GPU heatsink might cause a loss of pressure and start those issues.

OS X is universal, in that there are no differences between the version loaded on one computer and the other (at least for systems of the same processor type, with 10.4 PPC versus Intel was different). Using CCC to clone one to the other does work well, I've done it myself. 2.) I don't know if this will work or not. Is it possible to partition the iMac's hard drive, partition it with a 10GB portion that I could then use as an install DVD? If you have (or can acquire) a large enough USB stick you can make a boot volume from it . (Again they're cheap...If you have a Big Lots nearby, they routinely have large usb drives for ~$10 http://www.biglots.com/p/c/electronic-accessories/kodak-16gb-usb-flash-drive-or-memory-card is on right now. To make a bootable installer you need ones of these (10.4 may even fit on one as small as 4GB): 1) Put the USB stick into the computer, start Disk Utility. 2) Select the device (the one that has the brand name of the stick, not 'UNTITLED') and click on the Partition tab. 3) Select One Partition from the dropdown for partition number, then click on the Options button. Select 'Apple Partition Map'. continue with the repartitioning and formatting, it doesn't matter what it's called, as that will be overwritten in the next step. 4) Insert your 10.4 install DVD. 5) Select the 'Restore' tab from Disk Utility, and select (or drag) the 10.4 DVD to the Source, and select (or drag) your newly partitioned USB stick to the Destination. Do the restore. Voila! A bootable USB stick with your OS installer on it. This is actually much faster to install with than a DVD.

iMac G5, need to install OS, limited options
I just acquired a G5 iMac yesterday. As a long time Mac user, I was looking forward to tinkering around with it. However, there is no OS installed and the DVD drive is shoddy, so I am being a little fiddly with my solutions. A few facts first: 1.) I don't have a firewire cable. I can't remember where I had it last. It's somewhere, I just don't know where. 2.) I have several other Macs to aid in the process. 3.) I can pull the hard drive from the iMac and fiddle with it. From looking around most of the day, it seems I have two options, neither of which is entirely satisfactory, or maybe even possible. 1.) Clone the hard drive off my G4 mini onto the iMac. They will both run 10.4, but the last time I did this with a different computer, it messed up the permissions pretty badly, and I ended up reinstalling the OS anyways. Is this even possible to do with the differences between computers? 2.) I don't know if this will work or not. Is it possible to partition the iMac's hard drive, partition it with a 10GB portion that I could then use as an install DVD? Thanks for your help, I am a little stuck.

Dismantling iMac G5
hello, need to replace those nasty capacitors in my power supply module (it only runs fine in reduced cpu mode). Instead of shipping the entire computer to the nearest Mac shop I thought about taking only my power supply module to the local PC/console repair shop. I know there's tear down guide on iFixit site, but maybe someone could give me some tips on that. Particularly I would like to avoid getting white stripes on screen, people reported having after disassemling this iMac.

I would check to make sure it's properly connected. I'm not sure of the connection on the drive as the only iMac newer than a G4 I've worked on is a 2.16 GHz C2D one.

iMac G5 makes my xmas sad (help)
Hello, I bought this 17 iMac G5 1.9 Ghz iSight model with OSX 10.4.11. First issue I noticed was no response to Power button. The seller gave me a tip, which turned out to be resetting SMU procedure. Sometimes it helps, sometimes it gets powered off in the middle of BONG, figured out I need to pull the plug off, wait several minutes and try again.Yesterday finally managed to spare some time to play with it and there's another problem. When I use apps like Safari or games it starts that horrible fan noise (just like jet engine) and then... it gets to sleep! It wakes up successfully, but it happens again. I would contribute this getting into sleep mode with processor consuming apps. I guess it wouldnt get asleep when I was tinkering with OSX itself. My first diagnosis was bad power supply (regarding to Power On and sleep issues), even managed to find a Mac shop which offers PSU fixes for $20-$70. I am hesitating if I should give it a try and send it to forementioned service or just call it off and ask seller for refund. What's your bet - power supply or something worse like motherboard?

iMac G5 Motherboard repairs
I have noticed over the past year many requests for replacement iMac G5 motherboards on the swap group. I found myself in the same boat when I inherited 2 2006 G5 iMacs one 17 inch 2.0 ghz and one 20 inch 2.0 ghz. A further investigation I discovered a site that does replacement capacitor service on motherboards. His primary is replacement on non Macintosh motherboards but he will do the replacement on Mac's as well. The catch for Mac's is that he has no way to test the motherboard for Mac's when he is finished so you must be confident that your motherboard failure is due to blown or swollen Capacitors. The Site for much more information is ( www.badcaps.net ) The site tells you what caused the problems with the capacitors and other data. Also if you are interested in having him repair your mobo there is a form to fill out at the site. The cost at the time I had the repair done (Aug 2011) was $85.00/mobo plus $20.00 return shipping. This guy also sells Capacitor kits for the do it your self person. Bear in mind that Apple mobo's are multilayer boards and the components are soldered using lead free solder. This solder requires a hotter iron temperature for soldering than lead based solder and using lead based solder to replace the caps is not recommended. Another site ( www.jimwarholic.com/.2008/07/how-to-repair-apple-imac-g5.php ) gives you instructions for the do it your self. This site page also shows you which Capacitors ( @30 ) need to be replaced. For disassembly instructions ( www.ifixit.com ) has downloadable pdf Apple take apart instructions. This is a great service, both of my mobo's were repaired in about 3 weeks (time will vary depending on his backlog). Upon return I reinstalled the repaired mobo's and both computers booted and are working as per new.

Re: iMac G5 Motherboard repairs
I just finished doing the capacitor replacement on a G5 iMac. There are 30 capacitors on the board; however, uness a capacitor is swollen or popped, it does not need to be replaced. I only needed to do five capacitors. Several years earlier Apple had replaced about 25 capacitors and the five I replaced were ot done as part of the Apple recall. You need a soldering iron that can work at 800 degrees. Seven hundred did not get the job done. You must get all the old solder out of the whole and be careful putting the new capacitors in and make sure you get the polarity correct. Open the power supply, and confirm that the capacitors inside are good. Mine were fine. Doing this for the first time, I spent far more time on this than a professional would. This is not an easy DIY project. I had six hours into the research and actual work. Once complete, I reassembled the board and the components. Plugged in the iMac, and it immediately launched its OS. I ran it continuously for about 12 hours without a problem. Good luck with your project.

iMac G5 Capacitance issue
I have a 20 1.8ghz G5 with the famous not-so-hot capacitance on the motherboard. None of the capacitors has actually failed, but I was running into seemingly random freezes very regularly and had eliminated most other potential causes (memory, drive issue). As it turns out I found the reason it occurred at seemingly random times. On the iMac by default energy saver powers down the drive as often as possible. Depending on system load this can be fairly often. The apparently random freezes were occurring when the drive powered back up - the sudden power drain from accelerating the drive was the trigger for the capacitance issue raising its head. Not that this will solve problems with failed capacitors (although it may help prevent them), but turning off that feature in energy saver (system preferences) may solve freezing problems that can't be traced to bad RAM or disk problems. cheers -- You received this message because you are a member of the iMac Group, a group for those using Apple iMacs and eMacs.

Re: Upgrading imac, G5 or Intel?
I picked up an iMac G5 1.8GHz machine about a year ago for $300.

Re: Upgrading imac, G5 or Intel?
I think I heard that the G5 imacs can have issues with the capacitors on the logic board, but I don't know if they were limited to specific models/revisions. I'm not sure about the intel ones, or if they'll hold up to long term use (as the so-called bad G5 ones have had to). Having recently made the jump to intel myself (from a couple of G4 systems that still see use, fastest being a dual 1.25 MDD), they do seem a lot faster, and you get the added bonus that they're current tech, so likely to receive support/updates for a while yet (as long as they're core 2 duo or above), and you have the option of running windows, should you ever feel the need. Leopard will reach the dreaded two versions behind milestone in a few months. I just think the intel models will give you more options, and a more up to date operating system/security updates, etc for at least a year or two, where the G5 seems like you're swapping one piece of outdated tech for a slightly faster piece of outdated tech. But, if the price differences are that great, it could be worth getting the G5, although I assume that that will at some point need updating to something newer and faster sooner. And I think the multiple processor/core setup REALLY helps everything feel faster, more responsive, etc. Just my opinions though!

Re: Upgrading imac, G5 or Intel?
Just beware of the known problems with a G5 iMac. The 1st generation G5 iMac had faulty capacitors, as well as power supplies, and the generation after that commonly had video chip problems. If you can get a 1st generation G5 iMac, that has good capacitors, and a good power supply, hopefully one that has been replaced, they are great machines. -Jonas -- You received this message because you are a member of the iMac Group, a group for those using Apple iMacs and eMacs.

Re: Upgrading imac, G5 or Intel?
However, PPC Macs are a dead end, and getting deader every day; unless the G5 literally falls into your lap, spend the extra bucks and get an intel iMac or Mini. I can echo this. My desktop (PPC G5 1.8 GHz, 2GB) has been in once for the video chip issues (and should go in again) and it's grumbling about it's capacitors just not working like they used to - I have to restart the thing multiple times/day...which was fine as I had my PowerBookG4but *that *has now died (won't recognise the HD on startup, other computers can't 'grab' it, I still want to try and save my info on there).so I'm down to the week old iPod Touch and this hobbling PPC desktop. Indeed, my needs are increasing (starting a new business) and I'll be getting a new Mac Book Pro as soon as I can spend the changebut in my investigation in what my next step would be, I did find that any PPC model is quite limiting. If I had just email, surfing and some composing to do, and I found a PPC machine for under $300 that I had confidence in, I'd probably get it. But I love thrift store-ing and garage sale-ing and have, at times, accumulated a bunch of *stuff*,...so take that sound advice as you will. Good luck!

Re: iMac G5 startup problem
Also, I forgot to say: If your mac doesn't make the special sound when starting up, it means that you have to ZAP the PRAM, by doing this when starting up: COMMAND+OPTION+P+R. If that doesn't solve the problem, you are in deep trouble. If your Mac doesn't make the startup chime on startup, it means that it didn't pass the hardware test, meaning something is wrong.

Would appreciate advice on selling - better to list as a whole system for fix or parts, or part it out and sell the components individually? Everything but the board is in great condition. Thanks for your time, Matt Roland Matt, What you've got is a parts machine which probably has a logic board suffering from the bad capacitor plague that affected most iMac G5s. If the iMac still chimes and attempts to boot before it goes into vacuum cleaner mode, there's a good chance that replacement of the 25 or so capacitors on the logic board will restore it to life. But there's also a chance that it won't, especially if failing caps managed to damage video circuitry. Your iMac also could have a problem with the video inverter if the screen won't light up. If I were you, I'd first try to sell it locally as a parts machine. Failing success there, I'd then offer it to LEM Swap members as a whole machine. If no one wants to pay the shipping charges plus a modest price for the parts (LCD, optical drive, hard drive, RAM, bluetooth/Airport/modem cards, power cable, fans, etc.), then I'd part it out. Of course, having the original Apple shipping box will make things easier all around as the LCD is a delicate piece of equipment that can be damaged all too easily in transit in a non-Apple box. I've successfully revived several G5 iMacs and eMacs by replacing capacitors on the logic board as well as in the power supply. It's hard work because Apple started using lead-free, high-temperature solder which means hobbyist-level removal/replacement of caps isn't easy.

According to the original owner it was taking more and more attempts (button presses) to start up before it wouldn't start at all. The problem very likely is bad capacitors in the power supply, as well as on the logic board. I've gotten the first diagnostic LED to come on in that generation of G5 iMac, which simply means enough power has gotten to the logic board to turn on the light. But after replacing the power supply capacitors (which I got here http://jimwarholic.com/2008/07/how-to-repair-apple-imac-g5.php), I got three lights and the iMac booted, even though there were more than a dozen leaking/bulging caps on the logic board. I've also done the same thing and gotten only two lights and some whirring from the hard drive. All the caps on the logic board looked OK, which is no guarantee they're working correctly by the way. After replacing the caps, I got three LEDs and the iMac booted. The caps in the power supply are much easier to replace than those on the logic boards, as you probably know. Make very sure that the replacement caps are soldered solidly to the boards. I examine the soldered legs of my replacements with a magnifying glass while gently wiggling the cap. It's very difficult to get new caps correctly soldered since Apple used lead-free solder with a high melting point during manufacture. As you already know, it's a trial/error/tribulation process. Reviving G5 iMacs can be a real trip. I recently got 4 17-inch G5 iMacs from the tech at the local Mac shop. He couldn't get them to boot and run reliably, so he gave them to me. I got all 4 up and running, even to the point of getting the POST chime. But, one had a bad inverter. One had a bad LVDS cable connector. Two had had only the five 16-volt caps on the logic board replaced. Two had bad power supplies. Two would not pass either Apple Hardware Test and consistently threw video artifacts and reported the same video error, which is typical of G5 iMacs that have suffered internal video chip damage because of bad caps/power supply problems. Long story short, after a lot of parts swapping around I managed to get two solid G5 iMacs out of the four, and those two had all caps replaced on both logic boards and power supplies.

The problem very likely is bad capacitors in the power supply, as well as on the logic board. I've gotten the first diagnostic LED to come on in that generation of G5 iMac, which simply means enough power has gotten to the logic board to turn on the light. But after replacing the power supply capacitors (which I got herehttp://jimwarholic.com/2008/07/how-to-repair-apple-imac-g5.php), I got three lights and the iMac booted, even though there were more than a dozen leaking/bulging caps on the logic board. I've also done the same thing and gotten only two lights and some whirring from the hard drive. All the caps on the logic board looked OK, which is no guarantee they're working correctly by the way. After replacing the caps, I got three LEDs and the iMac booted. The caps in the power supply are much easier to replace than those on the logic boards, as you probably know. Make very sure that the replacement caps are soldered solidly to the boards. I examine the soldered legs of my replacements with a magnifying glass while gently wiggling the cap. It's very difficult to get new caps correctly soldered since Apple used lead-free solder with a high melting point during manufacture. As you already know, it's a trial/error/tribulation process.

iMac G5 Cap Replacement Follow Up - I2C errors in ASD 2.5.2
Hey guys, a couple of months ago I looked here for some help with replacing the bad caps on my iMac g5 1.8Ghz 20' Well I did it! It starts up. It seems to be working. I ran Apple Service Diagnostic 2.5.2 on it WITHOUT an internal HD and I am getting 2 errors. The first is on the I2C - Register test. It simply says it failed. The second is on the temp sensor on the HD - also failed, but I suspect that is because there is no HD I couldn't find any info in this particular area on apples support service site or any of the service manuals. Anybody know what these errors mean? Is it possible I am getting the I2C error because there is no drive on the bus? Don't want to buy a new drive for this mac unless I am reasonably sure that I will be able to use it. Thanks so much!

iMac G5 not installing OS?
Hi, I have an iMac G5 with an isight camera that I got in a trade. The owner told me it just needs a hard drive, so I ran down to my local computer store and spent $50 on a 160GB SATA hard drive. Installed it in there and fired it up. booted to the boot selection menu, where I inserted the disc. It takes anywhere from 10-20 minutes to finish loading the boot selection menu, and then when I click the install disc, it goes to the apple screen, but no spinning lines under it. It never loads the spinning loading symbol. I was wondering if anyone had any input to this idea. I have tried target disc mode, and it boots into it after around 15 minutes, but it does not show anything on my MacBooks or PowerBooks desktop. Not sure what is going on here but would love it get it going, very nice machine with the 1.9ghz PowerPC G5. I am trying to install Tiger by the way. Thanks!

iMac G5 video
Hi. I am new to this group but not new to LEM lists. I have seen some early G5 iMacs for sale that have caught my eye - specifically a 1.8 ghz 17 iMac. I am not sure if it is the earlier one (part of the 1.6 and 1.8 release) or the later one (part of the 1.8 and 2.0 release). My specific question: Can I attach an external monitor and run 2 monitors at once? If so would it be mirroring or expanding the desktop? If this model can't do that, is there a more modern one that will? Thanks in advance.

Re: iMac G5 1.8Ghz 20' capacitor replacement
Just to add my C$0.02 worth of opinion: lead-free solder is unlike your lead-loaded solder (63/37 or 60/40). Aside from the much higher melting temperature (over 60 degrees Celsius, which brings it closer to 240 C), it behaves differently and doesn't wet (i.e., creates the nice solder joint) or shines as lead/tin. It normally contains Silver, Bismuth, Antimony and/or Copper among other such metals. Each lead-free assembly is usually marked with Pb-free in the silkscreen, or crossed-out Pb in a circle, or sometimes RoHS compliant. In reality, lead is allowed to be in the assembly, up to 0.1% by weight. This started as a noble idea by the EU, quickly copied by California and some other countries (China, Japan, south Korea come to mind), to address the dumping of consumer electronics with regular trash and the potential to contaminate ground water. The geniuses didn't realize that the cure is possibly worse then the problem: lead-free (Pb-free) is much more brittle thus will bring more failing electronic assemblies to the dump, which will increase the amount of garbage. Tin whiskers, as well as other maladies, are also an issue, so be gentle with your electronics.

If nothing else, try twisting two wires together and soldering them together. If done right they should be very hard to pull apart. If these are through hole capacitors the solder should form a cone. It shouldn't take more than 10-15 seconds per solder joint. Longer than this and you might damage the cap. To remove the old ones, heat one side until the solder flows then push the cap away from that side, to pull the lead slightly through the hole. Then repeat on the other lead. Go back and forth this way a few times and you should have them out. If your tools include a solder sucker or solder braid use them to remove any excess solder. There ought to be some guides on the Web you can find about these. You might want to consider finding someone with some experience to show you the ropes and/or do the job for you.

It has Classic installed and I have a number of old programs on it and I have no problems with it opening with the correct application. In fact I have some real old apps that I haven't used in years, I hadn't used them since I was using a system running OS 9. For some of the documents I didn't realize I still had the app installed until I double clicked on the doc and it launched the app under Classic. And I have also used the Change All quite successfully. Thanks for your response and your report that Tiger works properly with Classic on your computer. I wish I knew how to make Classic on my iMac G5 work under Tiger as well as your G4 does. Since writing my first message to this group, I tried the Change All command; I only succeeded in making all of my text files created by BBEdit Lite appear now as TextEdit files. Several years ago I found that I could restore the Creator Application as the Opening Application by replacing the preference file com.apple.LaunchServices.plist with an older version of the same file. That remedy worked again today. Without my knowing why, the camera import problem has now disappeared. I can now use Image Capture or iPhoto or Canon's CameraWindow -- they all work properly. All I did was to install the version of Mac OS X 10.4.2 (the original system that came with the iMac G5) on a bootable external FireWire drive, and later booted up with that drive to test the installation. I don't see how this could have affected the system on my computer's internal HD, but it apparently did. So at the moment I seem to be back to where I was before I sent my original message. I hope my system stays in good condition from now on. Thanks to all who made suggestions. I haven't had time, with all the system installations, research, and attempts at repair, to read the iMac list for the past three days, but I hope to catch up next week.

Then the camera is not being seen by the hardware. Have you tried a different USB port? Console offers a slew of other log files. I looked at a few, but couldn't make sense of them and don't have a clue as to which, if any, might deal with import from a camera. None except system and console log are apropos. Given the number of security vulnerabilities that have been fixed over the years, 10.4.6 - 10.4.11, plus those in the layered products (QuickTime, Safari, etc), plus the various security updates... trouble-free is a sad excuse. This is the equivalent of driving down a highway at 80mph with no seatbelt, high on scooby snacks, and justifying it because you haven't crashed yet. I don't understand your point here. Are you saying that I may have picked up some malware that has caused this problem of not recognizing the camera? I am aware that a number of theoretical vulnerabilities have been discovered and fixed by Apple since 10.4.6, but not that any exploits of these vulnerablities have actually been found in the wild. I'm saying that you're unnecessarily leaving yourself vulnerable. Case in point: the malformed dmg problem. Not a virus or intentional malware usually (other than some idiots forwarding the bad dmg files to their friends for the heck of it). Just malformed dmg files that will panic an unpatched Mac when you try to open them. You're also avoiding all the other bug fixes and features that the developers put their efforts into providing. eg: Improved jpg color table handling and faster decode algorithms in the newer vers of QuickTime. Also, my impression is that if such exploits exist, they would require that the user cooperate by opening and installing some disguised malware. That's true of trojans but not other types of malware. and have installed all of Apple's Security Updates for Tiger on a PPC.

http://groups.google.com/group/imaclist/t/507c8814deed1d96In reply To Fabian Fang: Yes, I have a USB card reader. I don't use it regularly because the automatic upload with Canon's software is more convenient -- it sorts the photos into new folders pre-labeled by the date the pictures were taken, and places them in the right location for display and processing. Also, the automatic import makes it unnecessary to remove the memory card from the camera and then replace it after the transfer. Admittedly, these are minor conveniences, but to me they are worth some loss of battery power. -- You received this message because you are a member of the iMac Group, a group for those using Apple iMacs and eMacs.

Camera won't upload to iMac G5
Recently I have been unable to import photos from my digital camera (Canon PowerShot S80) to my iMac G5 running 10.4.6. Formerly, the process was automatic: When I connected the camera via its USB cable, Canon's CameraWindow program would open and the camera screen would soon show that it was ready to transfer the new (or all) photos stored on the camera's SD card. Now I have to open CameraWindow manually from Applications, and after some delay it tells me No camera was found. I called Canon's help line and tried a number of things suggested by a very knowledgeable representative (he was not afraid of Macs!). First he asked if I was using the genuine Canon USB cable with no intervening hub -- yes, I was. Next I demonstrated that iPhoto also does not see the camera. Then I tried to open Image Capture manually; its icon bounced in the Dock for a while but all it did was freeze the computer. The rep then suggested I try another computer. As soon as I connected the camera to my wife's iMac Core 2 Duo (running 10.5.8), iPhoto opened, offered to import photos from the camera, and did so successfully. When I closed iPhoto and opened Image Capture manually, it also volunteered to import photos. These tests convinced me and the Canon rep that nothing was wrong with the camera, but there was a problem with the iMac G5. He could not help me further. On my own I have tried the following: Removed recently-installed third-party software on this iMac (specifically Perian, Flip4Mac, DefaultFolder X); stopped Classic; closed every open application; relaunched the Finder; and trashed the CameraWindow preferences -- all without effect. Then I disconnected all external devices (every USB cable except for the camera and the keyboard, all FireWire cables, and even the Ethernet cable) -- no effect. Short of re-installing Mac OS X, I'm out of ideas. Any suggestions? Could my recent installation of Adobe's latest version of Flash Player be relevant?
