Dock disappears randomly on macOS Tahoe 26.0

I've reported this bug as well. It's related to the screen saver. I've tried to understand what makes it trigger. Because sometimes when you try to enter computer when screen saver is active, it shows desktop then pops right back into screen saver... now that's one bug, and the other is that it "wakes up" twice.. real quick, the display goes black two times and the dock disappears, and you have to turn on / off dock auto-hide in the system pref to restore it.

One **** of an annoying bug that needs to be fixed asap because it's also effecting my Studio Display because I think it turns itself on/off real fast when this happens.

Happening to me as well...quick solution that works for me is to lock/unlock my Mac.

You will probably have to wait for the first Tahoe .1 update for a fix. It’s apparent now that that many of us are seeing the same thing.

I have the same issue; after the screen saver runs, the dock is hidden. Sometimes it flashes back into screen saver mode for a half second too, then shows the desktop, it's kind of strange. However, turning the auto-hide on in settings, then back off, seems to force the dock to show again.

I have the same issue on my Mac Mini M4. My solution is to toggle Settings/Desktop & Dock/Automatically hide and show the Dock

It does not fix the issue, but it may be a quicker way to make the Dock visible again: press Command-Option-D.

This is a toggle, i.e. it switches between autohide and no autohide.

(Personal rant: why do people want the Dock always visible, anyway?)

One of many issues with Tahoe. What a piece of junk this release is, from bugs to aesthetics. Anyhoo, I had to create an Apple Script and put it on my desktop, next to my dock, so every time this happens I just double click the script.

tell application "System Events" to set the autohide of the dock preferences to true
delay 1
tell application "System Events" to set the autohide of the dock preferences to false

Okay, here's an odd thing. I like the dock on the right side of my screen with the folders. That's where it keeps disappearing. I moved the dock to the bottom, for 1 program, and the dock stays open.

Mine came back when I logged out and back in.

Dock disappears ever since upgrade to Tahoe 26.0. I can bring it back with putting computeer to sleep.

Hi,

Same here since upgrading to Tahoe, after the iMac gos into screensaver, dock disappears, the only way to get it back, is to go into system preferences, click on desktop & dock, click on hide then unhide to fix this.

Maybe some underlying bugs remaining.

It doesn't stick. Tried that several times, restarted my Mac Mini. HOWEVER, moving my dock from the side to the bottom seems to be holding.

Still having issues on and off, I can’t even get the dock to pop up, when I drag the mouse to the bottom of the screen, got go on the left side hit systems preferences and click hide then unhide. .

Maybe Apple is reading all these comments and make changes for the next update.

The Problem is, if you Enable and Disable Auto-Hide via Settings or Option+Command+D to make the Dock reappear, the Dock will not disappear in Full Windowed Mode Apps or games which is annoying like heck. You have to disable it every time while gaming for example or the Dock will overlay the Game window in any case. The only working fixes are a reboot or simple using terminal and rund "killall Dock". If you are plagued too often by this bug, just create a shell script that you can double click on your desktop to make this solution a bit more comfortable.

It is a failure of Mac Os in changing randomly the behavior of the Dock !!!

I know full well that you experience a problem - the Dock disappears even though it wasn't supposed to.

Don't you understand the meaning of WORKAROUND?

Only Apple can fix a bug. Nothing us users can do except report it.

While the problem persists, there is a QUICK and EASY way to show the Dock again: Command-Option-D.

If this is not helpful, perhaps you prefer to go to System Settings every time you need to show the Dock again.
