I've had a G5 dual core for about 3-years now and recently purchased a new 8-core Mac-Pro since I do primarily digital cinema/audio work and allot of the new codecs require an intel-core (and cause the G5 was getting a little slow for heavy HD work and rendering). The problem is, is that apple shipped the system with stupid Snow Leopard, which is fine for most of my apps... Except protools. Protools runs like complete garbage in Snow Leopard. It's practically unusable. I NEED to be able to run protools 8 right now and for the longest time I was screwed. After some fudging around I was able to target a disk in my G5 from my macbook, install, and successfully run my macbook's osx 10.5 on my G5. Which isn't all bad, because the G5 is a pretty good recording computer, but it would be nice to have it all on my new macpro, which won't boot 10.5 at all. Any ideas? Will the newer macpro's that shipped with Snow Leopard even boot 10.5?
