MacOS High Sierra boot drive
Is it possible to turn my external drive into a bootable drive?
I'm running High Sierra 10.13.6 on my MBP and want the external drive exclusively for live music recording. I would be connecting to internet via ethernet. I don't have enough space on my internal drive also I want as little background activity as possible, so would not be installing any other apps on the external drive. I don't know if this is possible? Thanks for any suggestions.
