I need help with having Intel Mobile 945 installed 10.5.6 iPC vanilla kernel and then upgraded to 10.5.8. I don't need to change my resolution so that is not an issue. My issue is that Quartz Extreme says "Not Supported" in system profiler.
I really want to run iMovie but until this is fixed I cannot, because I get an error message that says Quartz Extreme is required.

I am a n00b in OS X things so if you have a solution that includes terminal work, please post a simple, easy follow guide. It would be must appreciated!
