I'm running CS3 on Leopard both on my Mac Pro desktop and MacBook Pro. No issues for me with the latest Adobe and Apple software updates.
I say go for it!
I'm using a current-gen MBP with PS CS3 on 10.5.4 with no issues. It's an awesome setup :smile:
Thans Jason, what are the specs on your MBP, the new 15" MBP I'm looking at will have 2.5ghz processor, 200gb 7200sata drive, 4gigs ram and a glossy screen. Any other/additional recommendations?
