Will this work on a PowerBook G4 10.4.11; 1.67 GHz; 1.5 GB DDR SDRAM; ATI Mobility Radeon 9700 ?.?.? I'm running Tiger 10.4.11 I found someone selling their FCPS 2 and wanted to find out before I buy it. I currently have FCP 5.5, but can't afford the upgrade price at this time. I did some research on this already but had mixed results on whether or not it would work on this machine. Any help would be appreciated.
