Quick answer: If your Mac Dock has disappeared, it is usually hidden rather than gone. Press Option-Command-D to toggle auto-hide, leave full screen with Control-Command-F, and check the bottom edge of any other display. If it still won't appear, quit any Dock replacement app, then restart the Dock with killall Dock in Terminal.

You go to open an app and the bottom of the screen is empty. No Finder, no Bin, no row of icons you spent an afternoon arranging. Just wallpaper.

The Dock is hard to lose. It is part of macOS, and if it quits, macOS starts it again. When it vanishes, something is hiding it, and the list of suspects is short. Here it is, most likely first. For the settings themselves (size, position, magnification), see our guide on how to customise the Dock on a Mac.

Is auto-hide switched on?

This is the most common reason, and the fastest to check. Press Option-Command-D. Apple's list of Mac keyboard shortcuts describes it as "show or hide the Dock", and it is easy to press by accident while reaching for another shortcut.

If that brings the Dock back, auto-hide was on. You can also check in System Settings > Desktop & Dock, where "Automatically hide and show the Dock" is the switch. Apple's Desktop & Dock settings page says a hidden Dock reappears when you move the pointer to the edge of the screen where it lives, so if yours is on the left or right, look there rather than at the bottom.

If the Dock pops up but takes a moment, that is the auto-hide delay. Our Dock customisation guide shows how to remove the auto-hide delay with one Terminal command.

Is an app in full screen?

Full screen hides the Dock on purpose. Apple's guide to using apps in full screen says you show or hide the Dock by moving the pointer to or away from its location. Nudge the pointer against the bottom edge and it should slide up.

Many apps reopen in full screen if they were left that way, which is why the Dock can seem to vanish the moment you open a browser. Press Control-Command-F, which Apple lists as "use or stop using the app in full screen", or hover over the green button at the top left of the window and choose Exit Full Screen.

If you want a big window without losing the Dock, choose a maximised window instead of full screen. Apple's full screen guide says the window expands but the menu bar and the Dock stay visible.

Has the Dock moved to another display?

With more than one screen, the Dock follows you. When the Dock sits at the bottom, it moves to whichever display you push the pointer against. Setapp's guide to moving the Dock describes the trick: move the pointer to the bottom edge of the screen you want and hold it there for a moment. It does not work with a side Dock.

So if you glanced at the other monitor with your pointer resting low, the Dock went with you. Go to that screen's bottom edge to fetch it back.

One setting pins it to a single screen. In Desktop & Dock, under Mission Control, Apple's settings page says that when "Displays have separate Spaces" is turned off, the Dock appears only on the main display. If you want it on your laptop screen and it keeps appearing on the external one, change which display is main in System Settings > Displays.

Is another app hiding it?

Dock replacement apps hide the real Dock while they run. DockFix, for example, says on its own site that it "hides the system Dock while it runs and restores it when you quit". Apps of this kind draw their own Dock instead, which is the point of them. Our roundup of Dock apps for Mac lists several.

If you installed one and then removed it, or it crashed, the system Dock should come back on its own. If it doesn't, quit it from its menu bar icon, or press Option-Command-Esc, select it and click Force Quit. Then restart the Dock as in the next section.

Is the Dock process stuck?

The Dock is an app like any other, and it can freeze. Open Terminal (in Applications > Utilities), type killall Dock and press Return. The Dock quits and macOS starts it again within a second or two.

Nothing is lost when you do this. Your icons, size and position come back exactly as they were. Users in an Apple Community thread about a vanishing Dock reported it as the quickest fix, and it is the same command our Dock customisation guide uses after each Terminal tweak.

If you'd rather not use Terminal, open Activity Monitor, search for "Dock", select it and click the stop button at the top. It relaunches the same way.

Is it a macOS bug?

Sometimes the Dock disappears because of macOS itself. That Apple Community thread, started in September 2025, is titled "Dock disappears randomly on macOS Tahoe 26.0". Several people reported the Dock going missing after waking from the screensaver, with killall Dock and Option-Command-D as temporary fixes. Later replies said the problem stopped after updating to macOS 26.1.

If the Dock keeps vanishing after an update, check for a newer one. Go to System Settings > General > Software Update. The Tahoe bug went away in a point release, and an update is safer than a pile of Terminal workarounds.

Are the Dock's settings scrambled?

If none of the above works, restart the Mac. It clears whatever is stuck in a way killall Dock sometimes doesn't.

If the Dock comes back but behaves oddly every time, its preferences file may be the problem. Resetting it puts the Dock back to Apple's defaults, which also removes every icon and spacer you added. The Dock reset steps are in our Dock customisation guide's FAQ; make a note of your apps before you run them.

Getting the Dock back, in order

  1. Press Option-Command-D and move the pointer to the edge where the Dock lives.
  2. Leave full screen with Control-Command-F or the green window button.
  3. Check every display. Push the pointer to the bottom edge of each screen and hold it.
  4. Quit any Dock replacement app, then run killall Dock in Terminal.
  5. Update macOS and restart. Reset the Dock only if it misbehaves every time.

Something to put back in it

Once the Dock is back, you may as well make it nice. Spellbin is our small paid Mac app that adds a pixel-art cauldron beside the Bin. Drop a file on it and a green flame carries the thumbnail up and dissolves it, and the file goes to the real Bin underneath. You unlock new skins as you go.

It lives in the Dock, so it vanishes when the Dock does. Since version 1.0.1 there is also a small cauldron in the menu bar, which doesn't. Download Spellbin if a hidden Dock seems like a waste of a good shelf.

The Dock is almost never gone. Something is hiding it, and it is usually you.

Frequently Asked Questions

How do I get my Dock back on my Mac?

To get the Mac Dock back, press Option-Command-D to turn off auto-hide, then move the pointer to the screen edge where the Dock sits. If an app is in full screen, press Control-Command-F to leave it. If the Dock still won't appear, type killall Dock in Terminal to restart it.

Why does my Mac Dock disappear in full screen?

The Mac Dock disappears in full screen because full screen gives the app the whole display. Apple's full screen guide says the Dock shows when you move the pointer to its location. To keep the Dock visible all the time, maximise the window instead of using full screen.

Why is my Mac Dock on the wrong monitor?

The Mac Dock moves to whichever display you push the pointer against at its bottom edge, so it can follow you to another monitor. Hold the pointer at the bottom of the screen you want to bring it back. With "Displays have separate Spaces" off, it stays on the main display.

Is it safe to use killall Dock on a Mac?

The killall Dock command is safe on a Mac. It quits the Dock process, and macOS starts it again within seconds with the same icons, size and position. It does not delete settings or files. It is also the standard way to apply Dock changes made with Terminal's defaults command.

Why does my Dock keep disappearing after an update?

A Dock that keeps disappearing after a macOS update is often a bug in that release. In 2025, users of macOS Tahoe 26.0 reported the Dock vanishing after the screensaver, and later said 26.1 fixed it. Install the latest update, and use killall Dock as a stopgap.

Final Takeaways

  • Try Option-Command-D first. Auto-hide switched on by accident is the most common cause.
  • Full screen hides the Dock by design. Move the pointer to the edge, or leave full screen.
  • On two screens, check both. The Dock follows the pointer to the bottom of the other display.
  • killall Dock is safe. It restarts the Dock with every setting intact.
  • Reset the Dock last. It wipes your layout, so save it for a Dock that misbehaves every time.
