Planning to triple boot with macOS, Windows, and Linux. Do I use/do Bootcamp before or after installing Linux?
Yes it does.As if you install Linux before using Bootcamp it will actually refuse to install and you will have to do it manually because you changed the partitioning scheme.


Bootcamp Windows
Install Linux
Install a bootmanager so you can get in all OSes as Linux won’t show up in the default GRUB(I advise refind)
