For some reason, the Dock with all the app icons has disappeared from my Mac. How do I get it to display again?

  • Welcome to Ask Different :) Invoke the keyboard shortcut Command + Option + D and see if the Dock shows up. – Nimesh Neema May 13 at 21:54

Apparently you have accidentally set the Dock to automatically hide by invoking the keyboard shortcut Command + Option + D. Re-invoke the same keyboard shortcut to toggle the setting and turn off auto hide.

You can also effect the same change by going to Apple Menu → System Preferences → Dock and uncheck Automatically hide and show the Dock setting.

If you wish to keep the Dock hidden, the same can also be shown as desired by moving the cursor to the edge of screen (by default Bottom) where the Dock is positioned (as seen in the Position on screen setting in the screenshot above).

  • Conversely you can move your mouse pointer to each side of the screen until it pops out. I'd start with the bottom as that is the default location, but it might have accidentally been moved to the left or right side of the screen. – Steve Chambers May 13 at 23:50

Go to System Preferences > Dock > Toggle on and off the "Automatically hide and show the Dock".

If the issue is still there, you may encountered a bug related to Dock(like I do everyday). Launch Terminal, input:

killall Dock

Then press enter. Most issue related to Dock can be solved this way.
