Default Re: Downgrading a New Mac Pro to 10.5.1?
It's true that you cannot install 10.5.1 on that machine if it shipped with 10.5.2. But there is another way if you have another computer around that can run 10.5.1. Use a second computer to install 10.5.1 on a firewire drive then clone that drive to the new Macpro. It will work.

I did it with a MacPro that shipped with 10.4.11 and I needed to downgrade to 10.4.9 according to Digi specs. I did it and have had no problems. Used Carbon Copy Cloner.
