What would be the alternative anyway? Imagine a DJ playing a set and suddenly having Windows force an update on them. Linux during some periods barely played audio for regular use cases.
If you want good hardware and a reliable operating system, you go with a Mac. A few annoyances with adapters it might require won't change that at all.
Anecdotally the surprising answer might be rather old BeOS based systems. At least that's what I saw once and apparently some people still use some old tools that are BeOS only for audio (from talking to the DJ) :D
Except me. My employer doesn't let me use my own computer and refuses to buy me one.
