At this point in my development career, I pretty much always leave hidden files showing. The extra system ones that I come across from time to time just don’t bother me anymore. Problem is, sometimes I need to show files on a new computer – mine or someone else’s that I happen to be working on.
For that reason, I’m pasting this here for my future self to look back on for reference.
In the “Terminal” app – or any other command line utility – paste in the following lines of text:
# Always show hidden files defaults write com.apple.finder AppleShowAllFiles YES # Reset Finder for the settings to take effect killall Dock
Side note: that last one can also be accomplished through relaunching Finder through the Mac OS user interface, but this is just easier to do in one fell swoop.
