I always honestly equated Mac nerds with Linux nerds.
Hear me out...
For starters, macOS is certified UNIX, so it can actually be fairly CLI-friendly and has relatively decent interoperability with Linux.
I've known several Linux nerds who swore by Macs for audio/video production. They all used Linux primarily but had a decent Mac around for A/V stuff.
Anyway, Linux users (in my experience) are often artsy and weird and different, honestly a lot like the target demographic users for Apple products, except Linux users have less emphasis on the Corporate Memphis aspect of their personalities.
