How to Show Hidden File on a Mac

In the past, the only way I knew how to show hidden files on a mac was to run a terminal command which I had the commands show and hide aliased to.

# Show/hide hidden files in Finder
alias show="defaults write com.apple.finder AppleShowAllFiles -bool true && killall Finder"
alias hide="defaults write com.apple.finder AppleShowAllFiles -bool false && killall Finder"

This works great but is not the easiest command to remember and you have to open a terminal to run them. With the release of macOS Sierra Apple added a Finder keyboard shortcut that makes it possible to quickly show all the hidden files and folders. You just need to do the following:

  1. Open the Finder
  2. Browse any folder with hidden files
  3. Hold down Cmd + Shift + .  to toggle showing and hiding of files
