Apple was popular with musicians pre-OSX though. So I'm not sure that the modern APIs explain it. Logic has arguably become more unstable since the Apple acquisition and its modernisation. The Atari ST running Steinberg was probably the high point of stability for me. Regarding OSX, IMHO I don't believe it is particularly well suited to audio work, and the same argument applies to Windows. AFAIK both have no true realtime capability, such that a minimum amount of CPU resource can be guaranteed for an audio stream so that it is glitch free. QNX Neutrino and RTLinux offer this, but their use has typically been embedded systems. A live gig is therefore always a gamble. Some background process, like software update or icloud, could spring into action and cause glitches at any time. This is made worse by power management that throttles down your CPU and sleeps your IO devices.
