At the college I was at last year all the Macs were "deep frozen" - this means that all the programs and system info was on one HD and then there was a Student HD which you could save files to.
there was also some shit that just wiped anything on the desktop or not in one of the designated folders when the computer turned off (think that's the frozen bit)
Anyways, I got a new Macbook, want to use it exclusively for production, and want to split my Mac in a similar way that they did it at my college except without the deleting everything.
Also anything else you ca do to optimize ur mac for logic. (not in Logic but in the Mac itself)
