Re: [Avid-L2] How to create a 10.6 startup drive on a new MacPro with 10.8?

There is a board check in the installer that your machine won't pass
because the board didn't exist yet.

This can be easily defeated using Hackintosh trickery, if you are really
into doing it, I can point you in the right direction. Sounds like you got
it sorted in less sporting fashion, though :)
