Fix MacBook Pro touch bar freezing or not responding to application issues.
Recently, I came across an issue where I end up reaching out to Apple support team.
In a normal scenario, Apple touch bar updates it’s screen toward an application that you are using.
For examples, in Safari
Or in the Apple Mail.
Some odd reason this was completely frozen to the default button menu state and restarting “TouchBarServer” did not solve my issue.
The buttons were working and customizable but it was just not changing toward the application that I was using.
Here are the steps that you can follow to fix the possible issue.
Using finder. Go to Go tab and go to Library by holding on to Option key in your keyboard.
The file path to the file should be.
/Users/(yourUserName)/Library/Preferences/Look for the file com.apple.touchbar.agent.plist and move the trash can.
Make sure you only delete the filename above.
Do not empty out trash can for the backup purpose for now.
Next, go to the Caches folder
/Users/(yourUserName)/Library/Caches/Move everything inside Caches folder into the trash can.
Make sure you only delete the content inside Caches folders.
(Caches folder temporary stores application stuff for the loading speed. It will repopulate them as you use the application again.)
Reboot your system.
Your touch bar should be working correctly and changing to the application you are using.
I hope this helps and saves some time for the power users not having to call Apple or go through their tier cycles.
Ps. If something goes wrong. You can always restore whatever you deleted to the trash can and reboot the system to bring back to normal.
Also for other weird frozen state issues. You can simply refresh them by using this command in terminal.
