I have found that on ocassion you may need to see some of the hidden files and folders in OSX, mainly for troubleshooting. When enabled things can appear very messy and untidy so in my opinion it is best to make things visible, then when you are done, hide them again.
Good luck.
To enable hidden files/folders in finder windows:
– Open Finder
– Open the Utilities folder
– Open a terminal window
– Copy and paste the following line in:
defaults write com.apple.Finder AppleShowAllFiles YES
– Press return
– Now hold ‘alt’ on the keyboard and right click on the Finder icon
– Click on Relaunch
You will now see all the hidden files and folders. Once you are finished, perform the steps above however, replace the terminal command in step 4 with:
defaults write com.apple.Finder AppleShowAllFiles NO
