On the Mac, a lot of programs hide the .zzz extension by default. Is there a way to turn this behaviour off so that extensions are never hidden by default?
I know I don't actually need it, I just prefer it to be there.

AppleShowAllExtensions controls this behavior. It defaults to
false). Read the value by entering this in a terminal:
defaults read -g AppleShowAllExtensions
Set it to
true) by entering the following in a terminal:
defaults write -g AppleShowAllExtensions -bool TRUE
To also restart the Finder so that the change takes effect immediately (rather than after restarting / logging out & back in):
defaults write -g AppleShowAllExtensions -bool TRUE && killall Finder
To reset to the default value (and restart the Finder):
defaults delete -g AppleShowAllExtensions && killall Finder
