It’s easy to view hidden files in Windows. A little more difficult on a Mac. Here is a post about how to create a couple scripts to hide/show hidden files using Apple’s Automator. You can just type the commands into the terminal if you rarely need to view hidden files.
Using the terminal you just need the following to show hidden files:
# defaults write com.apple.Finder AppleShowAllFiles YES
# KillAll Finder
To rehide type:
# defaults write com.apple.Finder AppleShowAllFiles YES
# KillAll Finder
