You can add a ‘Recent Items menu’ to the OS X Dock. The default is set to “Recent Applications” but once the Dock item exists you can adjust it to feature other recent items too. Use the following defaults write command.
defaults write com.apple.dock persistent-others -array-add '{ "tile-data" = { "list-type" = 1; }; "tile-type" = "recents-tile"; }'
Restart Dock with the following command:
killall Dock
If you want to remove the Recent Items menu, just drag it out of your Dock.
Awesome 😀
