Since the release of macOS Sierra, when in Finder, it is now possible to use the shortcut:

 CMD + SHIFT + .

Show/Hide Hidden Files the Long Way

The long way to show hidden Mac OS X files is as follows:

  1. Open Terminal found in Finder > Applications > Utilities
  2. In Terminal, paste the following: defaults write com.apple.finder AppleShowAllFiles YES
  3. Press return
  4. Hold the ‘Option/alt’ key, then right click on the Finder icon in the dock and click Relaunch.

This will show all hidden files. To hide them again, follow the same steps but replace the Terminal command with:

defaults write com.apple.finder AppleShowAllFiles NO
