Just upgraded the wife's original Macbook to Snow Leopard and spent a lot of time updating and tweaking apps for compatibility. After a couple of hours of work, I just realized I don't know whether Final Cut Pro 6 will have problems. Anybody using it with 10.6?
As for upgrading to FCP 7, the minimum system requirements are steeper, so not sure I want to push my luck with this old Macbook with only 64 MB VRAM.
