Re: core duo imac project

[Melvyn & Edith Halbert]

Bill,

As Valter suggested, overheating is a prime suspect.  I had an iMac G5 whose 
display began to act up after almost five years of trouble-free use and the 
fans began blowing loud.  I found that the circular air vent under the support 
arm was plugged solid with dust.  Using the open end of our vacuum cleaner's 
attachments hose, I cleaned out all the dust in the vent and presto! the iMac 
began to work normally again.  I also opened the RAM port at the bottom and 
found very little dust actually inside the iMac.  It ran well for another year 
and a half before it developed a fatal freeze-up problem due to a failure on 
the logic board.

Question about Finder Copy

[Melvyn & Edith Halbert]

I often use the Finder to Copy a bunch of files from my iMac's internal hard 
drive to some external device.  Occasionally an error message pops up that says 
'An item named "" already exists in this location.  Do you want to replace it 
with the one you're moving?'  The error message sometimes includes a dot for 
the name of a problem file (".").  

When this error occurs with a bunch of files, I have found no easy way to 
determine what the real filename is or which application created that file.  
Some of the files being copied were created from webpages saved from Safari, 
but most of them are text files created by Text Edit in its rtf mode (but 
without the extension .rtf).  

I never saw this error before I started using Lion.  

Has anyone seen similar behavior in Finder Copy?  Does anyone know what to do 
about it?

Position of TextEdit window

[Melvyn & Edith Halbert]

On re-opening a file created or edited with Apple's TextEdit, its window 
appears on screen at a standard position -- it's always in the upper left.  
Sometimes I drag a window to a more convenient position before I close that 
file, but the next time I open the same file it appears at the standard 
position.  

Is there a way to tell TextEdit to open an existing file at the same place on 
screen it occupied the last time it was closed?  (This was normal behavior in 
older Mac OS systems, but was a victim of the advancement to OS X.)

If not, I can switch to using TextWrangler for text documents since TW does 
remember the last screen position of a file window.  But first I have to master 
some peculiarities.  For example, as my system is now configured, 
double-clicking on a text file created with TW opens it in TextEdit!  

(iMac Core i5 quad, Lion 10.7.4, TextWrangler 4.0.1)

Where are Mail messages kept?

[Melvyn & Edith Halbert]

•   Anders Fager / Gottick  Apr 18 04:09PM +0200 
 
•   
•   In the Mail-app. Any one has the slightest ide where the actull 
file is? I like to move it from computer A to computer B.
•   

Anders,

Your Inbox, Sent, and Trash mailboxes are not on your computer.  Any messages 
in those mailboxes are in your Internet Service Provider's storage facility.  
If you haven't deleted your mail messages from your ISP, or have not copied 
them to your own computer ("On My Mac"), then some or all of them should still 
be on your ISP's storage facility. 

Any messages that you have copied to mailboxes that you created under "On My 
Mac" are in mailbox folders located in 
/User/MyUserName/Library/Mail/Mailboxes/.  Each message is a separate file 
within its Mailbox folder.

In Mac OS X 10.6 and earlier, you can easily find your messages by looking in 
your own Library for Mailboxes, as explained above. 

In Lion (OS X 10.7), the user's Library is hidden by default, so the Mailboxes 
are also hidden.  There are simple ways to defeat this, either temporarily or 
permanently.  Be warned that Apple discourages this, as many people have messed 
up their computers by making changes in Library; that is probably why they have 
hidden Library in Lion.

To show the Library and its contents temporarily, pull down the Finder's Help 
and enter Library; move your cursor onto the line that shows the word 
"Library".  The Go column will then show Library with a big blue arrow; double 
click on Library.  To change Lion's default so that the Library is always 
shown, see (for example) 
.  

If your interest is simply to move Mail messages from one computer to another, 
your best and safest method is to use Mail's Export command on Computer A and 
the Import command on Computer B.  (Note that in Mail.app v3 and earlier, the 
Export command is called "Archive mailbox…".)

(I don't know why your April 5 response appeared in my In box only 
today, but that seems to be what happened.)


For cleaning the dirt from my iMac, I used our home's canister-style 
vacuum, with its brush attachment at the end of the long hose.  I 
think most upright vacuum cleaners also have attachments for a vacuum 
hose.  A shop vac would also do the job if that's what you have in 
your house.


I have a USB-powered vacuum, but the airstream is so weak that it 
never occurred to me to use it for this purpose.


I don't think you should worry about your vacuum cleaner being too 
powerful.  Everything inside your iMac ought to be screwed down, 
soldered in place, and any connectors ought to be firmly in their 
sockets.  I can't imagine that there's anything loose inside there 
that would be sucked out of its proper place.

issues with Core Duo imac

[Melvyn & Edith Halbert]

 Topic: 
issues 
with Core Duo imac


Before you start taking your iMac apart, be sure to vacuum out all 
external air-circulation vents, particularly the circular inlet on 
the rear under the support arm.  That inlet on my G5 iMac (last of 
the breed, which has the same case as yours) was almost completely 
matted with dirt that caused various display problems after the 
machine had time to warm up.  Cleaning this inlet (and a bit of dust 
in the RAM-access region behind the removable panel at the bottom of 
the computer) restored the machine to normal behavior -- no trouble 
whatsoever for the past year.

Each of these three major versions of the iMac G5 seems to have been

iLife package bundled with my machine was iLife '05, whereas some 
people who bought nominally the same model of iMac G5 received iLife 
'06 with their computer.  But I don't know if my hardware is any 
different from what was in the machines that came with iLife '06.

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.

Thanks for this suggestion.  When I followed what you wrote, there 
were no messages added to either the Console log or the System log. 
I think this is consistent with the response of the three programs 
(iPhoto, Image Capture, and Canon's Camera Window), none of which saw 
that a camera had been connected.  I also tried opening Image Capture 
before switching on the camera, but there was again no response from 
Image Capture nor any change in these two log files.

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.

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.  Also, my impression is that if such exploits 
exist, they would require that the user cooperate by opening and 
installing some disguised malware.  I have been careful not to allow 
this to occur, and have installed all of Apple's Security Updates for 
Tiger on a PPC.

Reply to Bill Chapman:

I use several programs under Classic which have no equivalent under 
OS X.  Mac OS X 10.4.7 (and all later versions of Tiger) won't 
automatically open files created under Classic in the application 
that created them.  Instead it opens them with some other 
application, not of my choice.

Worse yet, when OS X 10.4.7 (or later) is installed, without asking 
the user's permission it changes the Creator of _all_ such files (of 
which I have tens of thousands).  The original Creator code can be 
restored for one file at a time with the Finder's Get Info... 
command, but the Change All... option is broken in 10.4.7 and later; 
it isn't feasible to restore the Creator manually for tens of 
thousands of files.

I have found from experience that the latest version of Mac OS X that 
does not behave this way is OS X 10.4.6, so this is the version I 
continue to use.

My Mac at work is required by our IT department to run the last 
version of Tiger, so I know first hand how inconvenient it would be 
for me to run 10.4.11 on my iMac G5 at home.

Re: Camera won't upload to iMac G5

[Melvyn & Edith Halbert]

In 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.

Camera won't upload to iMac G5

[Melvyn & Edith Halbert]

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?

[Please, no comments about the perils of using an old version of Mac 
OS X -- for almost three years, camera imports have been trouble-free 
under this OS.]
