In addition to the
MacBook, MacBook Pro, and MacBook Air EFI updates, the
iMac EFI firmware was also updated to version 1.3. Apple says that this update "fixes several issues to improve the stability of iMac computers."
You can download this update by opening Software Update (Apple menu > Software Update) or by downloading the installer package from the
Apple's support website.
Please note:
To complete the firmware update process, please follow the instructions in the updater application (/Applications/Utilities/iMac EFI Firmware Update.app). The updater will launch automatically when the Installer closes.

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."
