MacOS Finder - Make it show all of the files in the directory
Does your MacOS Finder not show all the files when you go to / ? Hmm.
Have you got installed stuff into /opt, and is it not listed? Hmm?
Does it drive up the wall?
If Yes, then run this :)
# defaults write com.apple.finder AppleShowAllFiles YES
Or it might be as your own user. I cannot remember, but it ought to work.
$ defaults write com.apple.finder AppleShowAllFiles YES
And then you will love the Finder a little more.
Merry Christmas!
