/opt folder no longer accessible in finder on Catalina I have always been able to save to the /opt folder. I recently upgraded to macOS Catalina and can no longer see this folder.
In Finder I am able to display hidden folders and I can see it once again. However, when going to the Save As dialog in various programs I cannot see it there.
How can I make /opt visible again?
Make sure that you are using /System/Volumes/Data/opt instead of /opt, because the later is not writable due to security features. If you are sure the folder is on the data partition, then chflags nohidden /System/Volumes/Data/opt should unhide it.
