Not OP, but I've used a Mac as my main computer since I was a kid in the mid 90s, and I've installed Linux on most of my Macs at some point or another since like 2002.
Every single time I've found it sufficiently cumbersome and glitchy that I moved back off of it within a few weeks. Last fall–needing a new computer, frustrated with the slow iOSification of MacOS, and anticipating months to years of compatibility issues with developer tools on the M1–I built a desktop PC and installed Ubuntu.
I figured if running Linux was as annoying as it had been on my Macs I'd just install windows and run a VM like I'd done for years on Mac, but it has been way smoother than I expected. There are still a few driver issues now and then, but I mostly just bought the newest hardware and didn't make much of an effort to ensure compatibility. I'm not sure I'll buy another Mac at this point, but if I do I'm not going to bother with Linux.
Not the OP, anyway I used Debian on my old Mac Mini (first model, PPC CPU) about 2007 or so as media player connected to a projector, all mounted on a wooden shelf over a door; very compact and fit nicely in the living room. I used a media player roughly similar to Kodi (can't remember the name atm) that loaded just after boot without requiring login, set up to connect automatically to my NFS NAS and present all media as browseable directories; I later also added a USB TV dongle for DVB-T TV, so it was practical enough to be used by the girlfriend who isn't much into computers. A wireless IR keyboard with sort of a trackball (actually a giant equivalent of the Thinkpad red mouse "thing") completed it. It lasted a few years though, as pretty soon I discovered that a Raspberry PI that cost about 1/25 could do almost the same things, so I gave the Mini to a relative of mine who is an architect, and never heard that awful loud "boonnnnng" sound again. I had to fiddle a bit with startup scripts, kernel recompiles etc. to bring it to useable level, today it would be probably a plain install, but was helpful and taught me a couple things.
As for MacOS, I tried it, it was like a large polished, beautiful, golden cage. It has every possible comfort, but it was still a cage, and it lasted a few hours before I installed Debian over it.
I've got a Mac Mini (2014?) that I bought for a Mac/Windows contract. Contract is long over so I wiped Windows and now dual-boot MacOS and Pop!_OS (a terrible name). Works fine. The machine is tolerably fast/quiet.
I'd scrub the MacOS entirely as I'm not a huge fan but still like to mess with Rocksmith now and again.
