You can revert application toolbars to their 10.x look by setting NSWindowSupportsAutomaticInlineTitle
. To set this for Finder, use com.apple.finder
as the domain.
Disclaimer (from the comments):
I always wish “killall Finder” had a disclaimer. It’s safer to log out and back in since killing finder can interrupt copies, spoil mounted share and other such items... they are clearly edge cases...
defaults write com.apple.finder NSWindowSupportsAutomaticInlineTitle -bool false
killall Finder
