Problems with Video Display on a new Aluminum iMac

[drh64]

I have had this happen on two different IMacs and only when we run AC 11.

It seems to be triggered by Itunes running at the same time.

Has anyone else witnessed this before? Any suggestions?

Just announced
Apple updates firmware for iMacs with Radeon 4850 graphics. "fixes intermittent system freeze issues..."

Maybe this will help?

Still nothing for the ATI X1600 etc. I think they've given up. Not enough complaints, or it's an impossibly expensive hardware issue. Seems the recommendation is to avoid ATI at all times!

Well, here's an interesting twist to the whole saga - a group of laptop owners (including Mac users) are suing Nvidia over problems with their graphics cards. Read more here.

Yes, I read about that. But the Nvidia issue appeared after the ATI issue (2006/2007 for laptops, still there in 2008 MacPros) that started this thread. Not much hope left, I think. I'd say, if it's fixable by software, I think Apple would have done it by now. So I guess it's not. I have no energy to sue.

The OSX 10.5.7 update is out. I haven't tried it yet, but sorry to say, there is no mention of the old ATI issues. Guess we'll have to live with them

You might want to read this,

…and lots of changes to audio and video (both ATI and Nvidia) drivers.

there might be some hope that 10.5.7 contains a fix.

...and also three (so far) articles here:

which report enough problems with this 10.5.7 update to convince me to put off downloading it for at least a few more days...

Cheers,

Karl,

I update a iMac, Macbook Pro and Mac Pro. The only problem I had was with the spinning blue screen on the MAc Pro which was the only one that I did not update using Software Update. After restarting I reinstalled the combo update (just in case) and the process worked fine the second time.

Thanks, Eduardo... that's reassuring. 🙂

Thanks, Eduardo, I did the mistake of relying on Apple's release notes. Let's hope for the best. (Like Karl, I usually put off updating for a few days until the heavy bugs have been reported on Macfixit and such. The prize goes to the guy who updated his server remotely, using Timbuktu over the Atlantic, and found it was down afterwards. Surprise? )
