OS X 10.11
broke USB support on Macs.
USB used to just work. Now it stops working after you connect ten or so devices - which is not a common thing, but not unusual in music studios. And external USB hubs only work if they have a specific generic name in the firmware ID.
Apparently if you hack your own kexts you can get it working again, kind of.

This. The Win 10 situation is beyond horrific. I would never have imagined that MS would set itself up for a class action suit like this. I know people who have had their PCs trashed by this forced upgrade, and they're really not happy about it.
But the alternatives are not great. Linux and OS X are both in similar "kind of works, mostly, except when not" states.
Consumer OS reliability and design has become an embarrassment for the entire industry.
