Auto Hide Your Dock In Macos
If you’re using macOS Big Sur or later, then you can no longer use the easy keyboard shortcut to auto-hide your dock. See the steps below to find out to toggle on and off auto-hide in macOS. (It’s still easy!)
If you’re using a macOS prior to Big Sur
You can change this option in System Preferences or you can simply type cmd + option + d from anywhere. This shortcut will toggle your dock between permanently displayed and hidden.
If you’re using an older macOS, you could also auto-hide the dock using terminal or remove multiple menu bars and docks.
Open “System Preferences”
From your Mac’s Launchpad, open up your System Preferences.
Open “Dock & Menu Bar” options
Find your “Dock & Menu Bar” icon near the top of System Preferences and select it.
Check “Automatically hide and show the Dock”
When you check “Automatically hide and show the Dock”, your dock will now auto-hide by default. If you move your mouse to your dock’s location, however, it will appear.
Auto-hide Menu Bar on Mac
You can check the “Automatically hide and show Menu Bar” selection to auto-hide the menu bar in macOS Big Sur or later.
Something else that’s cool you can do is add spacers to your dock!
