OS X Catalina - Dock has disappeared

Opt+cmd+D is working without resetting the dock

I have experienced this same issue after upgrading my MacBook Air 13" 2017 to macOS 10.15 Catalina. Rebooting the Mac caused Dock to disappear.

Running command defaults delete com.apple.dock; killall Dock in Terminal resolved the issue, but Dock disappears again after reboot.

I have no idea what is triggering the initial disappearance BUT

• Preferences -> Dock -> Size
• Click on the slider to change the size. This also makes the Dock disappear.
• You then have to click on the slider again to turn it back on in order for it to be visible

PLEASE FIX THIS APPLE IT IS REALLY REALLY ANNOYING

I have the same issue with the dock plus the "do not disturb" is reset to "on" every time after a reboot. I tried all the fixes described here in addition to spending several hours on the phone with Apple support to no avail. I am kind of responsible for my issues because for the first time ever I updated MACOS the easy way instead of erasing the hard drive, installing MACOS from a USB and then using time machine or a clone to copy the apps. I learned my lesson and I reinstalled it. Everything is working just fine now.

Yes, I'm having the same issue after upgrading to Catalina on my 2017 MacBook. The only way I can get the dock back is to "Restart". Then it appears. However after "Shut down", the next time I boot up the dock is again gone and won't appear until I "Restart". Seems like a bug.

I have this problem too. To me it happens just after booting up. Logging out and logging in solves the problem until next boot.

Well, here’s what fixed it for me.

I had a widget of Juice app ( The missing Bluetooth manager for macOS) on the Notification Centre. After I removed it, everything works as it should.

search for deleting the dock .plist string and you’ll find the solution.

Yes I have that update and I'm still missing the dock when I restarted. I just log out then log back in instead of restarting. The quality assurance team at apple screwed this one up.

One way to "fix it" until there is a fix from Apple is to create a new account. This worked for me.

I now have managed to get the dock to appear, but it will not “hide.” Candidly, not sure which maneuver caused it to open. I used the size slider in System Pref to get it to show up.

Try restart with Option+Command+D. It worked for my Mac Air.

Update 10.15.1 is out, this might fix the bug.

Hmmm. I just opened Mission Control on SysPref .... and it showed the upswipe.

I did that .... and went back to Dock .. and now it opens the way it used to..

again .. hmmm.

not sure what's different.

But Dock is now hiding and revealing...

THANKS ... for something. : )
