I've had my Mac Pro 2.6 1gig for 6 months now. Final Cut, Soundtrack Pro, Motion, etc ran smoothly. I added Windows XP, everything still worked fine. My gig space has about 5 gigs left due to a lot of video that I have captured and projects I've saved. For the last few days it's been extremely slow. So slow, that when I click on FILE the pinwheel pops up. Any move I make the pinwheel shows it face. I turned the the playback resolution and turned FCP to "Safe" Mode. Final Cut runs slow even on new projects I open that don't have anything in the timeline. I know that 1 Gig is weak and I will upgrade to a 4 gig Ram card soon. But what I want to figure out is why all of the sudden the Mac has slowed down. All other applications and browsers work fine. I don't speak Mac language very well, so please make it as simple as possible Sorry! I also am going to get my RAM from Memory2go.com! Does anyone know a better place??????
