My logicboard was replaced under warranty, and now when i try to use iMovie, I get an error explaining that my graphics card doesn't support Quartz Extreme. There were a few suggestions on this site that i tried (changing the display resolution), but none that worked. I don't know much about Quartz Extreme, is it like a Microsoft driver or firmware? I'm fairly knowledgable with Windows and PC hardware, but new to Mac.
Got a tip for us?
