My iBook is a 1.2ghz PowerPC G4 with 1.25gb of ram and is running Mac OSX 10.4.11. I'm wondering if anyone knows what version of Logic would be most up-to-date and compatible on this machine... It's probably damn old anyway, but I'm pinching pennies here. I'm hoping to find someone on eBay with original install discs for whatever version this machine can still handle. Thanks guys!!!
