This gets asked a lot especially from someone who just switched from Windows to macOS. When you open a New Finder Window on your mac. You might want to see all the hidden files in your folder as well.
The quickest way to do it is just by using a keyboard shortcut:
- Open a New Finder Window on the folder where you want to see the hidden files.
- Press ⌘ Command + ⇧ Shift + . (Period). To be exact, hold down the Command and Shift keys together, then press the Period key.
- The hidden files and folders will appear semi-transparent in the finder (see below).
Of course, some people may find it too distracting, in which case you can always hide them again by using the same keyboard shortcut.
