OS X Catalina - Dock has disappeared

Worked for me too, this is the only workaround that has actually worked out of 3 different methods. So thanks to BobbyDav.

This is getting absurd. I've tried every suggestion on here and while the doc will appear and function normally it suddenly disappears after a reboot.

Just click to resize, adjust and click again. It will show!

this solution solves my issue. Thanks for a quick one

Well, it brought back the dock BUT ALL THE NON-STANDARD DOCK APPS/ITEMS ARE NOW MISSING .. IT WILL TAKE A LONG TIME TO REBUILD IT .. DON'T DO THIS 'SOLUTION' !!

This is the most fundamental function for getting started. Apple really needs to send a fix. My dock showed up again. Too much time taken up repairing this. Thanks all for the help.

It looks like this issue was fixed in the software update that was pushed to me last night. The dock was there when I first booted up my Mac tonight. Hopefully it continues to work!

Agree!

Had the same issue, testing back and forth and came to the conclusion that every time I use my Logitech mouse the dock disappears. Running only track pad for now and the dock hasn't disappeared yet again at least.

The latest update seems to have resolved the issue. I think it is linked to peripheral devices, I saw several people mention having a second screen (which I do not) and another speaking about a Logitech mouse (which I have). Either way, glad it's fixed.

EASIEST & FASTEST FIX!!!

Okay, straight to the point.

Go to the search icon at the top right of the screen, search for "system preferences".

Go to "Dock"

Once on the Dock settings, simple click on the top slider for the Dock Size. You don't need to adjust the size, just simply click on the slider and your dock will re-appear.

No need to reboot your machine every time.

I actually found this totally by accident whilst messing around trying to figure out how to get my dock back. Hopefully this helps some of you until Apple decide to fix this obvious bug.

Judging by the few emails received lately on this subject, the bug may well be fixed, however the problems I had once Catalina was installed I'm staying with Mojave till absolutely sure the disappearing dock and other bugs are fixed.

Had the same problems with the missing dock in catalina. Tried all the mentioned solutions... nothing worked! Got angry and went on line to download a dock alternative. Found uBar. Downloaded and installed easy with 14 day trial... worked very well. Note this is not an ad, I have no affiliation with uBar. I put it where I always kept the dock. When I went to use the new dock, the old dock reappeared. Went to preferences and mage sure I unchecked auto hide again on the mac dock It now works fine. Guess I scared it. I’ll decide in 13 days if I want to buy uBar.

Here's how I fixed the problem on my particular configuration — macOS Catalina (version 10.v5) on an iMac (Retina 5K, 27-inch, 2017) with a single, built-in monitor:

First, I rebooted the machine. Then I opened Disk Utility, selected the First Aid button and followed the prompts until it finished its work. Finally, in System Preferences, in Dock, I once again unchecked the "Automatically hide and show the Dock" checkbox. This time, the change persisted; Everything is back to normal.

Thanks to everyone who suggested possible solutions.

I have same issues described. I have a MacBook Pro (Retina, 13-inch, Late 2012). I re-installed Catalina last night -- this fixed issue temporarily, but now my Dock has again disappeared. I can get the dock to appear briefly when I open System Preferences, click on DOCK, and adjust the "size" with the slider,,, but it disappears the moment I remove my curser from the slider "size" control.
