Released on Saturday, iMac EFI Firmware Update 1.4 (1.7MB) specifically addresses the hard lock-ups that occur at random and leave iMac users with the custom-order graphics with no choice but to reboot their systems to regain a usable computer, regardless of whether they're using Mac OS X or running Windows in Boot Camp.

It also mends problems owners have encountered which prevent the systems from waking properly from sleep when using Boot Camp, Apple says. The update requires Mac OS X 10.5.6 or later.

The company hasn't explained what has caused the problems, which have triggered lengthy discussions on Apple's support forums and, though producing different symptoms, have drawn parallels with an earlier ATI graphics freezing issue from 2007.

  • Model: AMD Radeon HD 4850, GDDR3 512MB Memory. Supports Mac OS. Best choice to replace the old card in iMac 2009 desktop pc. If you are uncertain about the compatibility, please contact us before ordering. The ATI Mobility Radeon HD 4850 should be comparable to the desktop HD 4830 and is therefore very good at resolutions below 1080p.
  • I ordered this graphic card for my Mac Pro (early 2008) because the original graphic card was no longer able to keep up the demands of current software like Apple's Motion or Final Cut Pro. I needed an OpenCL-capable graphics card or Intel HD Graphics 3000 or later. The original ATI Radeon HD 2600 XT couldn't cut the mustard for my current needs.
