Hi, I have a Mac Pro that I use for music sequencing, but the version of Pro Tools that I have will only run on a partly-updated version of Tiger. This means I can't run the latest iTunes, Firefox and so on. What I'd like to do is install a second hard drive, on which I'll put Snow Leopard, so I can use contemporary apps. This means I can keep my Pro Tools installation safe for work too. I'll switch which drive I'm booting with using System Preferences. Has anyone tried anything like this, and if so, what was the outcome? Will it work? Thanks for any advice!
