I have a 2011 quad core i5 21.5 inch iMac running os x lion. Final Cut studio 3 works fine on it, I've had only a few little hang ups with log and transfer but no complete crashes. Nothing to downgrade for. It all works fine. I have it running side by side with FCPX with 7toX transfer app from the Mac app store.
