Dock Tweaks

Disable Dock Autohide Animation

This tweak wins you back some screen real-estate and makes the dock feel snappier. Following the below makes the dock hidden by default even with non-fullscreened windows. On mouseover, the dock will unhide itself instantly with no animation.

Tip

These are my personal preferences. I spent a little time digging to get these settings, wrote this post and then found this immensely useful website macOS-defaults.com. Definitely go there for more info on defaults!

Press ⌘ + ⌥ + D to enable autohide.

defaults write com.apple.dock autohide-time-modifier -float 0
defaults write com.apple.Dock autohide-delay -float 0
killall Dock

You can set those -float values as desired. 0 is instant.

Note

The dock will still have an activation “pressure” behaviour in fullscreen apps which can’t be configured. Workaround is to fit the window with double click instead of fullscreening.

To revert, reset those adjustments with delete.

defaults delete com.apple.dock autohide-time-modifier
defaults delete com.apple.Dock autohide-delay
killall Dock
