I quickly upgraded to the newly released Mac operating System macOS Big Sur and liked my experience in the first few days. I think it’s great that we get a refreshing look all over.
Overall it looks like the updates take some inspiration in mobile UI design with a bit more spacious, rounded elements. Still they feel very good to use with the mouse.
While the installation stalled for around two hours at the 100% progress bar it luckily still finished afterwards. I did not experience any technical or compatbility issues with the OS or third-party apps at all so far otherwise.
The Verge just published their review of macOS Big Sur. It provides more insight into the update and also the changes that landed in Safari 14.
