FYI…
I have an iMac (2.66 GHz Intel Core 2 Duo Processor with 4 GB 1067 MHz DDR3 Memory). I’m running Version 10.5.8 (of Mac OS X).
My computer has been running fine.
Yesterday, I installed Final Cut Pro 7.0 and when I opened it, my computer nearly froze, going into extreme snail mode. (I’d move the mouse, and the desktop action would correspond like one minute later).
After restarting computer, I used Disk Utility, and used Repair Disk Permissions. After several minutes, it made some repairs. I closed, restarted, and tried FCP again. But same problem: once opened, the entire computer got super-sluggish.
Then I restarted, and tried upgrades. There was one. I downloaded, it added, I restarted, and same problem. Our problems sound similar.
I’m also reading about others having problems exclusively with putting fcp7 on their iMac, but not on their Mac laptops.
