Hey all, I'm probably going to buy one of the iMacs or Mac Pros whenever they are refreshed. But I have an interesting question: can two versions of OSX be run from the same Mac, either via different partitions on the same HD (if I buy an iMac) or via two different internal HDs (if I buy the Mac Pro + 2 internal HDs)? I ask because I am a Pro Tools user, and Pro Tools is often several weeks to months behind on making the product compatible with the latest build of OSX. So what I'd like ideally is to have 2 versions of OSX on my next Mac. One, which I'll use for everything non Pro Tools related, will run the latest and greatest version of OSX the day (or two) after it's released. The other version will be the last stable build of OSX that Digidesign has signed off for Pro Tools compatibility (which will likely be one build behind the other). Anyone know if this is possible? Will I be able to install different versions (which will initially be the same version at first) on either different partitions or different HDs? Thanks!
