So I had the same problem with my new Macbook I have a 2.1G Processor with 2GB ram. I installed only final cut and DVD studio pro. When I tried to launch the app, I got this message: Final Cut Pro reccomends that you have a quartz extreme capable video card. After reading Chrismo's post above, I went looking for this string of code to edit. It was perfect until I got to the MRCheckPro.bundle. I didn't know how to open it (now i realize i should have opened it with text edit) so I removed it from that place and dropped the whole thing on the desktop TAKE MRCheckPro.Bundle AND PUT IT ON THE DESKTOP. Now launch Final cut and all should be well with the world. I am about to update from 6.0.1 to 6.0.4 or whatever the newest ver. is. by keeping the file and not trashing it, if I have trouble updating the app. I can put it back for the update, then remove it again later. Hope this helps someone as much as it helped me. d OKAY after updating to 6.0.5, it installs another MRCheckPro.Bundle file in the same location. Remove it and your good to go. DO NOT DELETE THIS FILE, you will probably need it for udating later.
