Im a newbie so this was prob already said:

I was having all kinds of issues last night instaling stuff into my Apple 2.3 Dual W Tiger, Logic 7.1.

Hypersonic.....Forget it, It takes like 5 minutes for Logic to start cause it gets caught up on Hypersonic with that garbage AU manager thing.

Atmosphere.... Working now but still in the incompatable catagory (Im sure they will have a fix soon)

Spin Audio Roomverb....pfffff wont even show up in logic..hahaha Unreal

Im thinking about going back to my Old OSX. Will it affect the running speed of my 2.3? Is Tiger streamlined for the new G5s?
