This has already been blogged quite a few times by people, however I regularly have to google how to Show hidden files on Mac OS every time I re-build my Mac or buy a new one. Thanks to OSXDaily for the original information. Show Hidden Files on Mac OS X Launch terminal defaults write com.apple.Finder AppleShowAllFiles TRUE killall Finder Make sure you restart the finder by doing the killall command. If you want to hide the files again, follow these instructions: defaults write com.apple.Finder AppleShowAllFiles FALSE killall Finder Not much too it, just wish I could remember the command!
