Another bonus is that the MBP can drive high impedance headphones on the go, without needing an external audio interface.
It also helps that Logic was popular for awhile, and Pro Tools (the OG DAW) was a Mac thing, though Ableton overall is more popular these days.
On the video side Vegas Pro is used in a lot of production houses, and it does not run on Apple Silicon at all.
Add to that the fact that most of the audio interfaces were firewire and plug and play on mac and a real struggle on windows. With windows you also had to deal with ASIO, and once you picked your audio interface it has to be used for both inputs and outputs (still to this day) forcing you to compound interfaces with workarounds like Asio4All if you wanted to use different interfaces, while Mac os just lets you pick different interfaces for input and output
Linux had very interesting projects, unfortunately music production relies on a lot of expensive audio plugins that a lot of time come in installers and are a pain in the butt to use through proton/wine, when it's possible at all. That means that doing music production on Linux means possibly not using plugins you paid and not finding alternatives to them. It's a shame because I'd love to be able to only use Linux
With Apple removing Firewire support this Fall, and so many devices still plugging along in so many studios, I wonder what's going to happen this fall.
When I was at music college doing production courses, they exclusively taught Cubase on windows.
Also Protools was available on Windows from 1997 and was used in many PC based studios.
For studio movies, render farms are usually Linux but I think many workstation tasks are done on Apple machines. Or is that no longer true?
