Until I ended up with a MacBook that’s just broken enough for the job.
Otherwise, it’s in perfect condition and still a cracking little computer.
I downloaded thePlex server Mac applicationfrom the website, installed it, and ran it.
From there, the process was identical to add my media files to a Plex library.
After all, Plex is on lots of operating systems, includingLinux.
I tried watching multiple 4K streams on different devices, and it went off without a hitch.
Like an M1 Mac Mini that you pick up used for a bargain, perhaps.
