Refresh Touch Bar
When coping with issues like MacBook Touch Bar not working, one of the most effective fixes is to kill the Touch Bar process and restart it. By refreshing Touch Bar, macOS will clean the memory and resources used by it, then assign it new ones.
It's particularly helpful when dealing with Mac Touch Bar not lighting up. You can either refresh the Touch bar using the Activity Monitor or Terminal.
How to refresh Touch Bar on MacBook Pro with Activity Monitor:
- Launch Activity Monitor from Finder > Applications > Utilities.
- Locate a process called TouchBarServer.
The process is labeled Touch Bar Agent on MacBook Pros running macOS 10.12 Sierra and earlier.
- Select the process and click the x icon to force quit it.
- Click Force Quit to close the "TouchBarServer" process.
You will soon notice the Touch Bar going blank for a moment and then return to normal while macOS closes the Touch Bar, allocating new resources to it and restarting the TouchBarServer.
How to refresh Touch Bar on MacBook Pro with Terminal:
- Open Terminal from Finder > Applications > Utilities.
- Paste the following command and press Enter.
On MacBook Pros running macOS 10.13 High Sierra and later:sudo pkill TouchBarServer On MacBook Pros running macOS 10.12 Sierra and earlier:pkill Touch Bar agent
- Enter your password and hit Enter to proceed.
Refreshing Touch Bar is also proved to be useful for cases like MacBook Pro Touch Bar not showing up or Touch Bar working but no display.
Did this fix solve the "MacBook Pro Touch Bar disappeared" issue? If it fails, proceed to the other solutions down below.
Refresh Control Strip
The Control Strip refers to the right side of the Touch Bar, where you can adjust brightness, turn up/down the volume and ask Siri. If you find the right side of Touch Bar not working, refreshing the Control Strip is likely the fix. You should also give it a try if you are facing issues such as Touch Bar not showing up or stopping responding to the shortcuts.
How to refresh Control Strip on Mac:
- Go to Finder > Applications > Utilities > Terminal.
- Type in the following command and press Enter.killall ControlStrip
Refreshing Control Strip should have fixed issues regarding the right side of the Touch Bar (e.g., Mac Touch Bar brightness not working). But if it didn't work as expected, you should check the display settings.
Check Touch Bar display settings
- Go to the Apple menu > System Preferences > Keyboard.
- Select "App Controls" or "App Controls with Control Strip" into the "Touch Bar shows" field.
If the Touch bar is set to show "Expanded Control Strip" instead of "App Controls," you will find the Touch Bar not changing with apps.
Also, take a look at your keyboard setting (System Preferences > Accessibility > Keyboard > Hardware) and ensure that the "Enable slow keys" option is disabled. If enabled, it may render the Mac Touch Bar volume not working.
Clear the Touch Bar cache files
The temporary cache files generated and stored on Mac to speed up processes may get full or corrupted, causing Touch Bar to malfunction. Similarly, its preferences configuration may also cause trouble. Thus, it makes sense to reset the Touch Bar's cache files and preferences.
How to reset Touch Bar cache files and app preferences on MacBook Pro:
- Open Finder.
- Click on the Go menu and select Go to Folder.
- Enter this path to Touch Bar's app preferences: ~Library/Preferences/
- Find the file with the name apple.touchbar.agent.plist, then delete it.
- Head to this path to the Caches folder: ~Library/Caches/
- Delete all the contents in the folder.
Remember to delete what's in the folder but not the folder itself. Otherwise, some applications may fail to work.
- Restart your Mac.
Modify Sound Output
Is the Mac Touch Bar volume slider not working right after plugging in an external display? If it is, you need to go to the Apple menu > System Preferences > Sound and select the Output tab. Try to switch the Output device and see if the Touch Bar works. You can also try with headphones, then switch to your external speaker.
If you have no success yet, it's time to update macOS.
A new macOS update provides security patches and improves support for apps and other features like Touch Bar. If you are using an old version of macOS, consider updating to the latest available to your Mac model.
Go to the Apple menu > System Preferences > Software Update to update macOS, then install the available update.
Given that the initial update may contain bugs resulting in Touch Bar not working, you should install the latest combo update to see whether Touch Bar goes back to normal. The chances are that software compatibility and glitches are also why users experience Touch Bar not working after the update to Big Sur or Monterey.
If a recent update crashed Touch Bar and got the Touch Bar options disappeared in the Keyboard settings of your MacBook Pro, you need to run Disk Utility First Aid to repair the Mac disk. If First Aid reports no issues, try to reinstall macOS without erasing the hard drive.
If Touch Bar still won't respond or light up, move on to reset the SMC and NVRAM.
Reset SMC and NVRAM
The System Management Controller (SMC) is responsible for low-level functions related to physical parts like keyboard, LED indicator, battery, CPU, etc. If the Mac Touch Bar doesn't light up or the right side of Touch Bar disappeared, resetting the SMC may fix it. Note that the M1-powered Mac doesn't need an SMC reset.
If resetting the SMC doesn't fix the Touch Bar on MacBook Pro, try to reset the NVRAM.
Ask Apple Support for help
If none of these solutions solved the Touch Bar issues on your Intel or M1 Mac, your Mac likely has hardware problems like water damage, broken parts, or loose connections. Accordingly, you should seek help from Apple Support and have them run a thorough hardware test on your MacBook Pro.
If the "MacBook Touch Bar not working" problem happened after a keyboard replacement, you need to bring it back to the technician who replaced the keyboard and asks him to fix it.
Many users have also posted the MacBook Pro Touch Bar flickering issue - Touch Bar flashes with a bright white square when it's inactive. Unfortunately, this is a hardware problem too. Except for running Apple Diagnostics to determine which hardware component is at fault and go to professionals, there's not much you can do to handle the flickering Touch Bar.
