Mac is definitely not the platform of choice of tinkerers and developers.
Linux is, and the audio drivers blow. (So much that nothing meaningful can be done with the OS).
Go figure.
The Muse Receptors run a modified Linux kernel though (which in and of itself is way closer to OSX than Win). I want to DIY one of those, I'd really rather use free VSTs live than most of these rackmount processor shits.
