I'm sure I've messed up the name powerpc. I have a mac that runs the other animal but can't run Snow Leopard. It has the unix based system. I sure do need to get educated on the terminology but I think you'll be able to help me dispite my limitations. I have iLife '08 and intended to wait until version '10 was released. Now I'm not so certain that my computer will support this new version. Does anyone have insight into the minimum OS requirements for this release? If I can't upgrade, would you recommend that I grab iLife '09? I would only use the Movie and DVD portion of this SW as all my photos are in Lightroom. I have no intention of using Garage Band or iWeb. Thanks everyone.
