Apple posts fix for graphics woes on 27-inch iMacs

updated 04:05 pm EST, Mon December 21, 2009

Problems linked to ATI cards

Apple has released a new graphics firmware update, directed at 27-inch iMacs. The patch fixes flickering and corruption problems, which Apple attributes to the Radeon HD 4670 and 4850 video cards the computers may be equipped with. Downloaders must have Mac OS X 10.6.2, and avoid any sort of power interruption during the update process.

The glitches may be one of the reasons behind recent shipping delays, which pushed delivery times to over two weeks. People have also mentioned cracked screens; NPD analyst Stephen Baker suggests that the issue is simply one of high sales, rather than any technical difficulties. Apple has not provided any official explanation for the situation.

    The video he used was no problem on my Mac

    JTV - Gotye - Learnalilgivinanlovin on youtube barely used up 25% of processing power (with no spikes) on my 3.06 GHz 24" iMac and ran totally smooth in Snow Leopard. But believe it or not when I had it running in VMWare 3.0.1, WinXP Pro SP3, IE8 and the latest flash player, it only used up a measly 30% and that includes the 12% to 15% when VMWare was just sitting idle. I have Snow Leopard tuned to a T and it runs great. I had used an Adobe Flash uninstaller some weeks back and did a fresh install. I'll try running that video in BootCamp/WinXP Pro and I'll bet it'll barely use up 10% processing power. That is some steaming c*** and Adobe can go to h***.
