Sorry about that Cody (and everyone); my e-mail has been down all day and I just received about 100 e-mails all at once. I am adding this to the post now.

Well, that didn't fix the lockup issues when dealing with anything graphics heavy. (aka games, screen savers, itunes visualizer... depressing) :(

Must be limited to recent models of IMac? My wife's 17" Intel Core 2 Duo says it is just fine and dandy thank you with FW 1.2 and doesn't see any reason to update. Or has Apple forgotten her?

The update doesn't apply to older iMacs, such as my 17" Intel Core 2 Duo. I tried downloading it manually, and when I launched the installer package, it says "This computer does not need the update."

I am having trouble making the iMac EFI Firmware Update 1.3. The instructions screen appears - which then followed upon the restart they appear again. Dialogged window reads at the bottom
"If these instructions appear on your screen again, the firmware update was not successful. Repeat steps 2, 3 and 4."
Which when I follow through it happens again, thus allowing to be unsuccessful. Is there anyway that you know of to troubleshoot this??
Thanks is advance if you can!!
