okay, it's me again... I got home and put the software on both my macbook AND my G5 1.6ghz... the requirements say I need at least a dual 2.0... apparently not... so far so good! Woohoo! Though my laptop runs everything, I do still use my G5 as my work horse, I didn't want to do all my vid on my laptop. So there. Woohoo!
Keep us informed as you use it over the next few days. I have a dual G5 and a single G5, as well as a Ti G4 laptop. I will install it on my Intel MacBook Pro 17", but may wait to see how users with g5s react, before I decide to buy the family pack.
