Re: Upgrade processor?
The only thing, i think you have to keep in mind (as I have one white CoreDuo iMac 17 and tested a little), is that the processor have to be a Meron Core 2 Duo or it will not turn on at all. I have tried a Penrin C2D and it did not worked! Marcelo Andrade +55 81 81521304 [Vivo] PSN ID: MarckOliver75 Sent from my iPhone.

Now would any know where I gat get a Core 2 Duo 2.16 processor besides pulling one from a machine? You're welcome, John. Sorry about the repeat of a good chunk of the text in my original post. I've got a Magic Trackpad next to my shortie bluetooth Apple keyboard, and for some reason that causes very strange things to happen to my e-mail text from time to time. Usually I catch it, but this time I didn't. Doesn't happen when I'm using a word processor, only with e-mail. Go figure. There are no other pitfalls to be encountered, other than the usual disassembly/assembly stuff that has to be done just so to avoid problems. Once you get to the bare cpu, all you have to do is insert a tiny flat blade screwdriver into the slot, turn it 180 degrees, and the cpu is loose and ready to be lifted out. Lots nicer than the old lift-the-lever sockets of olden dayes. I bought my Core 2 Duo cpus on eBay for quite reasonable prices, so there's no need to buy a complete Mac and strip it. Just make sure that the cpu you're buying is compatible with the socket. A 2.16 Core 2 Duo mobile chip should be a perfect, worry-free choice. Have fun!

Re: Upgrade processor?
The 2.16 would be a T7600, the fastest 667 MHz Core 2 Duo Mobile made. I don't believe they made any 800 MHz FSB Core Duo processors so I would try and find a T7600 for the max speed. If you aren't worried about speed a T5800 or a T7200 would also work, neither are that much slower than the other as the T7200 is 2 GHz and the T5800 is 1.8 GHz. -- You received this message because you are a member of the iMac Group, a group for those using Apple iMacs and eMacs.

Re: Upgrade processor?
I believe the CPUs in the Core Duo and Core 2 Duo iMacs are Laptop processors, at least the 2007 2.66 GHz Core 2 Duo iMac I worked on had the CPU identified by CPU-Z in Bootcamp with XP as a Mobile Core 2 Duo. As for upgrading, I'm sure it's possible. It was possible in the Mac Mini's so I don't see why it wouldn't be a socketed chip, it would take a lot of work to solder 478 pins as close together as they are. -- You received this message because you are a member of the iMac Group, a group for those using Apple iMacs and eMacs.

Here's the process. Keep in mind this was written in the very first days of Lion, so you may already have a USB Lion thumb driver installer, and thus can skip to Step 8: 1. Using a Lion-compatible Core 2 Duo or better Mac running OS X 10.6.8 that’s received all its latest Apple updates, click on the App Store icon in the Dock and buy OS X 10.7 (Build 11A511). When the almost 4 GB download is complete, it will appear in the Applications folder as Install Mac OS X Lion. 2. Right click on this installer icon, then select Show Package Contents, go to SharedSupport and find InstallESD.dmg. That’s the OS X 10.7 Lion installer. 3. Hold down the Option key, click on InstallESD.dmg and drag a copy of the installer to the desktop. (NOTE: If you upgrade your 10.6.8 Mac to Lion before doing steps 2. and 3., the Install Mac OS X Lion folder will disappear from Applications and you’ll have to re-download the Lion installer from the App Store. Pulling a copy of InstallESD.dmg to the desktop avoids this problem; you can delete it or move it to a backup drive to save space later.) 4. Open Disk Utility, then click on InstallESD.dmg and drag it to the left pane. 5. To burn a DVD, insert a DVD into the optical drive, select InstallESD.dmg, select Burn under Images in the menu bar, and burn the DVD. You will not use the DVD to upgrade your original Core Duo Mac to Lion, but you might as well make one now. 6. To make a bootable USB thumb drive, you will need one at least 8 GB in size. Insert it into a USB port, then select it in the left pane in Disk Utility. Click on the Partition tab, choose 1 Partition, choose Mac OS Extended (Journaled), name the drive Lion USB Installer or whatever you want, click on the Options button and select GUID as the partition type. Then tap on Apply and Disk Utility will erase and format your thumb drive so it will be bootable by any original Core 2 Duo or better Intel Mac. 7. Now you’re ready to install the OS X 10.7 InstallESD.dmg image on your USB thumb drive. Click Restore in the right pane of Disk Utility, then choose InstallESD.dmg as the Source by clicking on it in the left pane. Click on the USB thumb drive in the left pane and drag it to the Destination window in the right pane. Tap on Apply and Disk Utility will create an OS X 10.7 bootable installer on your USB thumb drive. 8. Obtain an external hard drive, preferably one with a USB 2.0 interface. Connect it to a known OS X 10.7-compatible Intel Core 2 Duo or better/newer Mac. Use Disk Utility to partition the drive in GUID, and name it whatever you wish. See 12. below for a suggestion about setting up a backup partition at this time. 9. Insert the USB Lion thumb drive into a port on your Lion-compatible Mac and use the InstallESD.dmg file to install OS X 10.7 Lion on the external USB 2.0 drive. The USB thumb drive will show up on the desktop as Mac OS X Install ESD; you do not have to boot from the thumb drive although it is bootable. Simply click on the white icon to launch the Lion installer, which needs a native Lion-compatible host Mac to run the installer. 10. When Lion has been installed, test it by booting from the USB external drive (hold down the Option key during restart and select the external
