Me too. In my experience they don’t fix a lot of issues, at least with the 2018/20 mini. I had display issues and kernal panics when i bought my mini in Dec 2018. Some things don’t change.... Funnily enough, my new W10 gaming pc runs flawlessly. How the tables have turned...For the first time in my Mac computing history (started using it at system 7.5.5) I'm going to keep my machines on Big Sur when MacOS 12 comes out. Too many bugs, too many problem, and it takes them forever to fix anything. I use my M1 MBP in the wilderness / off grid all the time for back country camping and I cannot afford to have it crap out on me because of some ****** bug they should have caught in QA.
