The macOS installer kept failing and I had to jump through hoops to download the installer for the macOS version I wanted and 'verify' it. (This was ~10.10-10.13, not sure if it's still as much trouble to verify an installer that isn't the latest version.) After the second Mac that refused to reinstall, I had had enough and put Ubuntu on it.
I started to realize around 2012 (with the release of soldered-RAM Retina MBPs and razor-edge discless iMacs) that Apple did not need me as a customer, and eventually I was fine with that. I have one remaining Mac Mini that I use as an HTPC and to get pictures off of my iPad. For daily use I usually prefer an old Thinkpad running Debian.
