I’ve just upgraded from Mojave to Catalina and plan to leave Big Sur for a while. My work are also being very cautious about upgrades to Big Sur.
I held off Catalina for a long time, especially when it became apparent that Logic Pro 10.6 was causing Overbridge issues, but they’ve released 10.6.2 which supposedly fixes these issues, so I’ve taken the leap to Catalina and Logic Pro 10.6.2.
I was having some audio issues which I think were due to Core Audio implementation, which I’m hoping will be fixed in Catalina. For me the only real imperative to upgrading to newer Mac OS versions is where built in drivers have known issues on the older version but are fixed in the newer ones.
