Top navigation disappears after upgrading to OSX 27.2

Since I upgrated to OSX 27.2 the top navigation frequently disappears regardless of which application I am using.


Is this a bug in 27.2?

Is there fix or correction for this issue?

A randomly disappearing menu bar is a known issue that has been reported by users of 3rd party Menu Bar utilities (Bartender, BetterTouchTool, etc.).


How to fix it:


Ensure your settings show the Menu Bar at all times

  • Open System Settings
  • Click on Menu Bar
  • Set the option to Automatically hide and show the menu bar to Never


Disable or Update Third-Party Menu Bar Apps:

  • If you use apps like Bartender or Ice, update them to a Golden Gate-compatible version.
  • Try quitting your menu bar utility apps entirely to see if the random disappearing stops.
  • Since these apps install system extensions, you may need to completely uninstall the app and all components to fix the issue.


Restart the MenuBarAgent or Your Mac:

  • If the menu bar vanishes mid-session, you can restart the background process via Activity Monitor by searching for MenuBarAgent and forcing it to quit (it will automatically relaunch).
  • A standard system reboot or booting into Safe Mode can also clear out corrupted interface caches


If the above do not work, then see if the problem is present when you boot in safe mode. That process performs some system cleanup and clears caches, and also disables 3rd party extensions that may cause problems.

 

Start up your Mac in safe mode - Apple Support


If that does not correct the issue, test in a new user account. A newly-created user account will have all settings at default, and if the issue does not occur in that new account then it provides guidance on what may need to be changed to correct the issue.

 

Add a user or group on Mac - Apple Support

 

Once the testing is complete, the new account can easily be deleted.


It might help to download and run EtreCheck, written by a long-time forum member. The free version is fine. Post the full report using the Additional Text button. No personal information is revealed. 



I cannot replicate this issue, but you are not the only one to report it. For example, see:

Hi Neuroanatomist,


Thanks for the instructions to try to fix disappearing act of the top navigation.

Unfortunately, the disappearing act is still occurring. I followed all of the options,

and the navigation still disappears.


Please note, for me, this issue only started happening after I updated my Mac with OSX 27.2.

I did not have this issue with previous versions of OSX.
