I have a dual 2.5 G5 and got FCP Studio yesterday. My system had Panther installed, but after reading that Motion would take advantage of some of the newer features in Tiger, I decided to make the jump. I installed Tiger, Installed FCP Studio and two hours later (lots of discs) I launched FCP. I have no problems to report, but I only played around with footage already on the system.
I’ll be doing more this week and will report any problems.
