MacOS – Unable to show hidden files on Mac

findermacosterminal

I just received a new MacBook, running OS X El Capitan 10.11.5, from my new employer and I am unable to force hidden files to show in Finder. This is my fourth MacBook, and in the past I have always used defaults write com.apple.finder AppleShowAllFiles YES to show hidden files; however, on my new Mac, this is not showing the hidden files. I also tried defaults write com.apple.finder AppleShowAllFiles TRUE but still cannot see hidden files in Terminal or in Finder. I restarted my computer, but that didn't solve my issue either. Any ideas on how to show my Mac's hidden files?

After you run the defaults write com.apple.finder AppleShowAllFiles YES command, hold the 'option/alt' key, then right click on the Finder icon in the dock and click Relaunch.
