If you wouldn’t have mentioned especially 'Big Sur' I would have applauded, but this version of Mac OS is simply a disappointment. It looks ugly, it feels sluggish (at least on Intel) and for me as a professional user this development goes in a very wrong direction. I really love Mac OS and I hope a better skilled designer will overtake this project and fix all the flaws in the next version. Until then I will avoid updating (I already made the mistake on one machine).
