On rare occasions, I encounter a frozen menu bar on my Mac. Perhaps you too have encountered a scenario where the beach ball appears when hovering over the menu bar. A lot of time, this can be resolved by killing the single app that’s causing problems. In other situations, you may need to completely kill and restart the menu bar to do the job.
The menu bar, more specifically the menu bar extras located on the right side of the screen, is controlled by the SystemUIServer process on macOS. Therefore, killing SystemUIServer will result in the menu bar restarting.
Restart the Menu Bar using Activity Monitor
Since there’s no way to restart the menu bar from the menu bar interface itself, you can use one of the following two methods to kill SystemUIServer and give it a friendly push.
Step 1: open Activity Monitor from /Applications/Utilities
Step 2: while on the Memory tab, search for SystemUIServer
Step 3: highlight the SystemUIServer process, click the ‘x’ button in the upper left-hand corner, and click Force Quit
Your menu bar should then quick and restart.
Restart the Menu Bar using Terminal
You can also kill and restart the menu bar from the Terminal.
Step 1: open Terminal
Step 2: type the following command and press Return on the keyboard
killall -KILL SystemUIServer
Although it should be rare, in times of need, this command is good to have in your back pocket. It will thus allow you to get back to work without an overly long interruption (restarting your Mac).
