Make Install
Switched from 'doze in '09. The MBP is still running, though a little long in the tooth. The more used laptop is a Framework running Fedora.
Back then, it took about a month to train my thumbs to press CMD instead of CTRL.
For Desktop, it's OpenCore. Was Clover back in '18 or so when I got stopped using the MBP as my daily driver. Not sure what a 128GB memory system with 4TB nVME storage and 6TB GPU would cost in MacLand (not to mention the two 28" 4K screens), but don't want to find out. As soon as I can repair a fruity device and add my own storage and memory again, may consider purchasing one, but even though I could afford it, am not prepared to pay their eye-watering prices.
Was tempted to play with Homebrew, but have been compiling code since the 80's, and OSX is Unix based so fairly straight-forward. Bit of a pain the way they lock down the system drive these days but you can always mount it then bless a snapshot if you really need to, which mostly you don't if you just set prefix to /usr/local like any sane 'nix box.
Do not like what they did to /Applications, though, and haven't found a way around it. Don't want to see every single app in one screen. Adobe has a folder, so do the Audio apps, editors, Video, etc. Used to be able to move the native Apple apps to their own folder, alas no more. So, a bash script to just open a finder window straight to the desired folder, and I don't have to see that crap I never run anyway.
Like Mr. Proven, don't use any Mac apps. FF, TB, iTerm, VS Code, Python, LibreOffice are enough to get by. Except for Python, don't compile those, but do give a few bucks to the Document Foundation every month. Don't listen to music on the desktop, it's streaming (mostly either a Swiss classical station, or SOMA FM out of San Francisco, the latter of which also gets a few bucks a month). Tunes are on the phone, which has an ever-growing catalog of purchased discs loaded on to it. No Spotify.
My nVidia Titan XP had to get retired a few years ago; it's in the TrueNas box now. The Titan Black still serves ably, but I don't care for ATI/AMD and have had to tweak things a bit to make it work properly on Ventura. Imagine it's almost time for an OS upgrade again; that's not difficult, just tedious, easier to load onto a fresh disk and use migration assistant to bring all the data back.
I do like the Mac OS, but before too long will have to figure out what to do when Intel support finally goes away. Honestly, though, since I spend so much time either in the editor or the terminal, could probably live without it, just am used to it.
