I thought so too. I run most of my sound content stuff from external 4TB Raid-0 via e-sata, which is blazing fast. :o)
Unfotunately, the installation caused a lot of trouble and hung up over a e-licensed plugin from Korg. (legacy collection) I managed to force it through, but still there is a lot of trouble. Mainstage does not come further than initialising jampacks, and stops responding on start and so on. Updated all apps of course. :o(
I am on to apple first thing in the morning.
Hey btw. fantastic tutorials here, glad Susan (dreamaiden) recommended you guys!
