So I made the jump from Mojave to Catalina yesterday. Had to go through and update some apps, find a new solution for my scanning software. All said and done everything is working fine now. I did have to upgrade my font management software, it was 64 bit but it would not run in Catalina. Adobe is all working fine and in general the OS feels very snappy. My biggest concern and reason for not moving ahead before was the 64 bit only OS. Now that I am here, is there anything I should worry about with apps not working if I just went to Big Sur? Differences I saw seem to be mainly cosmetic. Just wondering if there was known issues with Big Sur breaking apps or apps not working under this and if it is a stable OS?
