How to see hidden files in Finder

By default Finder does not show you the hidden files. If you ever need to see them there, do the following.

1. Open terminal and type in:
defaults write com.apple.Finder AppleShowAllFiles YES

2. Restart Finder app by holding ‘alt’ on the keyboard and right click on the Finder icon. Click on Relaunch.

If you need to revert to the previous state, do
defaults write com.apple.Finder AppleShowAllFiles NO
and then re-launch Finder again.
