I decided I wanted to use the 1TB HD that's in my brand new mac pro in my late 2005 Power Mac G5. I installed the HD and started up the Power Mac. I was planning to insert the OS X disk and have to reinstall the operating system. But it booted up fine and seems to be working perfectly. I thought I would have needed to reinstall OS X since the hardware/specs are completely different (especially the processor Intel V PowerPC). I thought it would be having some kind of Mac Pro in Power Mac body freak-out! Is that not the case? Can I go ahead and use this sucker without any dramas? I've read iMovie 09 isn't compatible with PowerPC. Will all the other system and iLife 09 software work OK? Thanks!
