Mac Dock Auto Hide Not Working? 7 Proven Fixes That Actually Work

Why Mac Dock Auto Hide Stops Working The dock auto-hide feature is one of macOS's most useful screen real estate savers, but it can be frustratingly unreliable. When it breaks, your dock stays permanently visible or becomes completely unresponsive to mouse movement. This usually happens after system updates, when certain apps interfere with dock behavior, or when macOS gets confused about display settings. The good news? Most dock auto-hide issues have straightforward fixes. Quick Fixes to Try First 1. Force Restart the Dock The fastest solution is often restarting the dock process entirely: Open Terminal (⌘ + Space, type "Terminal") Type: killall Dock Press Enter The dock will disappear briefly then restart with default behavior restored. This fixes about 70% of dock auto-hide issues. 2. Toggle Auto-Hide Off and On Sometimes the setting just needs a refresh: Open System Settings (or System Preferences on older macOS) Go to Desktop & Dock Turn off "Automatically hide and show the Dock"
