Add spacers to your macOS app dock to make groups
2020年10月13日
Open term (or equivalent) and paste the following one-liner:
defaults write com.apple.dock persistent-apps -array-add '{tile-data={}; tile-type="spacer-tile";}'; killall Dock
When the Dock restarts, there should be a draggable blank space that you can move anywhere. Repeat to your heart's desire.
