I have other machines running Lion and snow leopard for that. I just keep the old iMac as an off-line suite since it still works fine and i see no need to replace it (or upgrade the sys :)))
I might leave it on tiger, on second thoughts. I have some old PPC software that is fantastic, and anyways will be doing all the 4444 conforms for the offline edits in Davinci and Smoke.
But thanks for the low down!
BTW do you rate FCPX? it sure is a weird beast. I suppose it has to be learned, but it is like the fisher price of editing systems. Not bad, just different. I don’t like it’s lack of precision.
