Thanks. The two critical programs that need upgrades are SuperDuper! (I use it) and Carbon Copy Cloner (a number of folks use it). Either one is a stellar program. Obviously having a stable, secure backup program that works flawlessly is both mandatory and important.FYI, my homebrew and macports is working. Also, my apache/mariadb servers worked without change.
Again, I have 5 programs that are critical (including SuperDuper!), and hence am waiting before I move to Big Sur. Plus, Big Sur is nowhere near stable enough, at least for me.
