I’ve been on it since one of the earlier betas for testing reasons and it’s been a bumpy ride, I’ve filed more feedback than before. It’s definitely stabilised a lot though and feels reasonably solid today. There’s a few nagging visual bugs and weird performance spikes floating around though.
I had several problems with the early releases of Catalina, including my Apple-made USB keyboard not being recognized.
Even after it seemingly was fixed, a dot release would break it again. I did at least two clean installs to resolve the problem once a stable version of Catalina was released.
It's completely different with Big Sur. I upgraded my work machine to Big Sur. After the Spotlight indexing was done, everything was working as it was previously, except I had the latest and greatest operating system.
It's still only been a few days but so far, I have no complaints about Big Sur.
Loving the new desktop dynamic illustrations and how much faster Safari is, even compared to Catalina.
Obviously YMMV but so far, it's been smooth sailing with Big Sur.
