Force OSX Finder to Always Show Hidden Files
By default Mac OSX coddles the user by hiding system and “hidden” files (beginning with a period). This is counter-production to the power user in all of us, and an insult to our intelligence! End this madness with:
defaults write com.apple.finder AppleShowAllFiles YES
Then “Relaunch” Finder by
option+right-clicking on the Finder icon.
To change this back, do:
defaults write com.apple.finder AppleShowAllFiles NO
