I want to move to Mavericks, and it's looking like support for FCP 7 is fading. I knew it was going away all along, but I've become a bit attached I'm afraid. From all of the articles I've been able to find, FCP 7 will work on Mavericks, but some features may be problematic.
Thinking of Adobe Premiere/Creative Cloud. I already subscribe to CC, but with the current lull in development/project activity now is probably a good time to come up to speed.
