How to Keep the Mac Dock on One Screen in a Dual Monitor Setup

Sandy Writtenhouse Updated 06-04-2020

If you aren’t already, you should start using a dual monitor setup because it can really boost your productivity. Of course, there are also plenty of other reasons to have multiple monitors.

However, in recent versions of macOS, the Dock displays on all monitors by default. Many users like this, but maybe you don’t. Perhaps you prefer to keep the Dock on one screen.

To change this, you have two options. Unfortunately, both are nothing more than workarounds which may or may not be satisfactory for you. At this time, it’s all you can do, so let’s take a look.

Option One: Use a Single Space

Head to Apple menu > System Preferences and navigate to the Mission Control section. Uncheck the option called Displays have separate Spaces. For this change to apply, log out and back in.

Afterward, your Dock should stick to the primary monitor.

Downside: You lose other dual-monitor features. These include each display having its own menu bar and apps being able to run in full-screen view on each display.

Option Two: Position the Dock to the Side

For this, again open Apple menu > System Preferences, then navigate to the Dock section. Find the option called Position on screen and set it to either Left or Right. This will lock the Dock to one screen.

Downside: You won’t be able to use a bottom-edge Dock. This position also doesn’t play nicely if you have three or more monitors, because you’ll have too much screen estate to cross to reach the Dock.

Hopefully one of these two methods will work for locking your Dock to one screen.
