By default there are a number of files and folders which are hidden on Mac OS. This doesnt effect the average user but for the aspiring developer/people who link to tinker this can be a hindrance. Not to worry, follow this simple steps...
- Open Terminal you can either go to Finder > Applications > Utilities or you can hit Cmd + Space Bar and type terminal then press return.
- In Terminal, paste the following: defaults write com.apple.finder AppleShowAllFiles YES
- Press return.
- Finally you need to relaunch Finder, simply hold alt, and right click on the Finder icon and select Relaunch.
Boom, and that is it!
