This guide shows you how to modify the dock such that it will hide or show the instant you roll over it, rather than the annoying default delay.

*Note: If you're using macOS Big Sur or later, then you can do this via your Mac's settings. Check out our guide to see how to auto-hide the dock in macOS Big Sur or later.

If you haven't already, enable autohide. Navigate to System Preferences > Dock and select the Automatically hide and show the Dock option.

Navigate to Applications > Utilities > Terminal.

Paste the following command and press enter:

defaults write autohide-delay -float 0; killall Dock

Note: In MacOS Mojave and later, you might need to use this command instead:

defaults write autohide-delay -float 0.0001; killall Dock

Paste the following command and press enter:

defaults delete autohide-delay; killall Dock
