Jun 24, 2012 11:16 PM in response to Tony DeLucaby Tony DeLuca,One more thing. If I were to install 10.6.8 onto a drive in my old 2008 Mac pro, then move it to my new 3.06 12core, would it run safely. I don't want to see a kernel panic on my new computer.

Jun 25, 2012 12:53 AM in response to Tony DeLucaby X423424X,Universal apps should run if the app requirements are 10.6.x or greater. Some apps may have 10.7.x incompatibilities but you won't know until you try. That or check every app's requirements one by one (not worth it).
You can use your System Profiler, Applications to get a list of which apps are ppc only.
As for trying your 10.6.8 drive in your new machine. Should work. Try it. But if it panics you'll know. No big deal. Maybe you can find out what's causing the panic (perhaps a incompatible kext).

If you mean can you move v10.6.8 Snow Leopard on the 2008 Mac to the new Mac? No.
Don't install a version of Mac OS X earlier than what came with your Mac

Jun 29, 2012 10:29 AM in response to Tony DeLucaby vadrum,Hey Tony, did you receive the new "beast" in the meantime?
Was it possible to install SL without problems? If yes, you tried with the retail DVD or you did the thing with the old Mac Pro?
Please let us know, someone else is interested in buying and downgrading it aswell

Jun 29, 2012 11:03 AM in response to vadrumby Tony DeLuca,Well actually I received the beast, and it was on it's way back to Apple the very next day. The entire configuration was messed up! Wrong drives, wrong memory, wrong video card, and wrong processors. Someone on the shipping dock must have screwed up, sending my Mac to someone else, and his standard configuration to me. Very inconvenient! Luckily when it does come I can just install Snow Leopard on a blank internal drive on my 2008 Mac Pro, then move it to my new one. I know that will work, as my friend did this. That is if Apple dosen't screw up again, in which case I'll just cancel the order, and go with the HP 820z workstation.
