Show hide file in finder on Mac OS X

Show Hidden Files on your Mac

Launch the Terminal and enter these commands exactly as shown. The first command activates the ability to see the hidden files:

defaults write com.apple.Finder AppleShowAllFiles TRUE

Now you must relaunch the Finder by killing it, this is how the changes take effect:

killall Finder

If you want to hide hidden files again (those preceded with a .) and go back to the default Mac settings, you can just type the following:

defaults write com.apple.Finder AppleShowAllFiles FALSE

Again you will need to kill the Finder so that it can relaunch for changes to take effect:

killall Finder

That’s all there is to it!
