This is one of those silly little things that I always feel like I’m the last to learn. Admittedly, when I’m working with hidden files, I’m usually on the command line or in a text editor that already shows them.1
So, I must inform you, with no small amount of embarrassment, that today I learned the following. If you are in a Finder window, use the hotkey combination of
⌘-Shift-. and it will toggle visibility of hidden files!
Because I was a dirty Linux hippie before I switched to Mac about 15 years ago. ↩︎
