Keyboard shortcut to show hidden files on macOS Big Sur How do I toggle hidden files on/off?
In previous versions of OSX this was  ⌘ Command⇧ Shift.
It's not working anymore for me on macOS Big Sur.
⌘ Command⇧ Shift. still works. Check Keyboard Shortcuts to see if you have a shortcut overriding the toggle hidden files action
To permanently show hidden files, open terminal and type:
defaults write com.apple.finder AppleShowAllFiles true; killall Finder
