Last month I shared an email that Wolfram sent regarding incompatibility of Mathematica 12.0 with Mac OS 11 (Big Sur). Well, I just upgraded to Big Sur and decided to fire up Mathematica 12.0, to see if it would run, and it did. I tried some basic commands, and they executed. While I would say, this is good news on one level, am I alone in viewing the false "you must upgrade" emails as offensive?
My question is: Is Mathematica 12.0 supported on Big Sur? Are there any features that do not work correctly, and if yes, which ones?
