The MacBook Touch Bar offers a blend of aesthetics and functionality, giving users quick access to tools and shortcuts tailored to their needs. However, when the Touch Bar malfunctions or stops working, it can be a frustrating experience for users. This article dives deep into the nuances of a non-functioning MacBook Touch Bar, outlining the most common causes of this issue and providing comprehensive troubleshooting steps to restore its functionality.
Understanding the MacBook Touch Bar
The MacBook Touch Bar is a multi-touch enabled strip located above the keyboard, replacing the traditional function keys. It adapts to different applications, presenting relevant controls like volume, brightness adjustments, and app-specific shortcuts.
Features of the Touch Bar
Some notable features of the Touch Bar include:
- Dynamic Controls: The Touch Bar offers a seamless experience with tools and options that change depending on the application in use.
- Custom Shortcuts: Users can customize the Touch Bar to add their most-used functions, enhancing efficiency.
Common Symptoms of a Malfunctioning Touch Bar
Users may encounter several symptoms indicating the Touch Bar is not functioning correctly. These include:
- The Touch Bar remains completely blank.
- The Touch Bar does not respond to touch.
- Some functions work sporadically, while others do not.
Potential Causes for Touch Bar Malfunctions
Identifying the cause of a non-functioning Touch Bar is crucial in determining the right course of action. Here are several potential reasons for the issue.
Software Glitches
Often, the cause of a malfunctioning Touch Bar can be traced back to software issues, whether from outdated macOS or app-related glitches.
Corrupt System Preferences
Corrupted system preferences or settings can lead to problems with the Touch Bar. This corruption might occur after system updates or app installations.
Hardware Issues
In some cases, hardware malfunctions can lead to problems. These issues might differ from minor connection concerns to deeper internal problems.
Effective Troubleshooting Steps
If you find that your MacBook Touch Bar is not operating as intended, there are several troubleshooting steps you can take to remedy the situation.
1. Restart Your MacBook
The first step you should try is to restart your MacBook. This simple step can resolve many minor software glitches.
2. Force Quit Touch Bar Application
If the Touch Bar is still unresponsive after a restart, forcing the Touch Bar application to quit may help. Here’s how:
- Open the Terminal app.
- Type the command sudo pkill TouchBarServer and press Enter. This action will restart the Touch Bar server.
3. Update macOS
Keeping your macOS updated ensures that all functions, including the Touch Bar, operate effectively.
- Navigate to the Apple menu.
- Click on System Preferences.
- Select Software Update and follow any prompts to download and install updates.
4. Reset System Management Controller (SMC)
Another method for troubleshooting is resetting the SMC. The SMC is responsible for low-level system management functions on Intel-based MacBooks. To reset the SMC:
- Shut down your MacBook.
- Press and hold the Shift + Control + Option keys and the Power button for ten seconds.
- Release all keys and then turn on your MacBook.
5. Reset NVRAM/PRAM
NVRAM (non-volatile random-access memory) and PRAM (parameter random-access memory) hold system settings. Resetting them may resolve the issues with the Touch Bar:
- Shut down your MacBook.
- Turn on your Mac and immediately hold down the Option + Command + P + R keys for about twenty seconds.
- Release the keys, and your Mac should reboot.
6. Check for Conflicting Applications
If you are running software that may be conflicting with the Touch Bar, consider closing or uninstalling those applications to see if functionality improves.
When to Seek Professional Help
If none of the above steps yield results, you may need to consider the possibility of a hardware issue.
Identifying Hardware Issues
Signs that you could be facing a hardware malfunction include:
- Physical damage to the keyboard or Touch Bar.
- Overheating during use.

What should I do if my Touch Bar is not responding at all?
If your Touch Bar is completely unresponsive, the first step is to restart your MacBook. This can often resolve temporary glitches that may be affecting the Touch Bar. Click on the Apple logo in the upper left corner of the screen and select “Restart.” After the MacBook restarts, check if the Touch Bar is functioning properly. If it still doesn’t respond, consider resetting the Touch Bar.
Another option to reset the Touch Bar is to use Terminal. Open Terminal from the Utilities folder in Applications and type the command: sudo pkill TouchBarServer. Press Enter, and then enter your password when prompted. This process will restart the Touch Bar and may restore its functionality.
How can I reset the Touch Bar settings?
To reset the Touch Bar settings, you can go to the System Preferences. Click on the Apple logo, select “System Preferences,” and then choose “Keyboard.” Here, you will find the option to customize the Touch Bar settings. Making changes here can help if the Touch Bar is not displaying the expected controls or is behaving erratically.
If you want to fully reset the Touch Bar controls to default, you can remove any custom settings and restore it to factory defaults. In the same Keyboard preferences menu, locate the option labeled “Touch Bar shows.” Choose your preferred default setting, and this should recalibrate the Touch Bar to ensure it works as intended.
What should I do if certain Touch Bar features are not working?
If specific features of the Touch Bar are malfunctioning, you can first check if the application using those features is up to date. Sometimes, outdated applications may not be fully compatible with the Touch Bar. Ensure that both macOS and the offending app are running the latest versions. You can update your apps through the App Store or the app developer’s website.
If the issue persists, try checking the Touch Bar settings again in System Preferences. Some features may not be enabled by default or could be disabled inadvertently. You can also try running a macOS diagnostic by restarting your Mac while holding down the “D” key, which can help identify any underlying hardware issues affecting the Touch Bar features.
Is there a way to restore the Touch Bar to its default settings?
Yes, you can restore the Touch Bar to its default settings through System Preferences. Open System Preferences and navigate to “Keyboard.” Here, look for the “Touch Bar shows” dropdown menu, and select an option that suits your preferences, usually set to “App Controls” or “Expanded Control Strip.” This action will help reset any customized settings back to default.
In addition, if you have made extensive customizations, you may also want to reset the entire MacBook’s settings. This can be done by removing any custom input methods and returning other settings related to the keyboard and input devices to their factory defaults. This comprehensive approach can fix persistent issues affecting the Touch Bar’s functionality.
How can I troubleshoot if the Touch Bar keeps flickering or glitching?
If the Touch Bar is flickering or glitching, the first approach is to check for software updates. Apple often releases patches and updates that can resolve known bugs or glitches within macOS. Go to the Apple menu and select “About This Mac,” followed by “Software Update.” Download and install any available updates, as they might contain vital fixes for Touch Bar issues.
If software updates do not resolve the problem, try resetting the SMC (System Management Controller). To do this, shut down your MacBook, then press and hold the Shift + Control + Option keys and the power button simultaneously for about 10 seconds. Release all keys, and then press the power button to turn your MacBook back on. This reset may help with hardware-related flickering or irregular behavior of the Touch Bar.
What can I do if my Touch Bar settings are not saving after a restart?
If changes to your Touch Bar settings do not save after restarting your MacBook, the issue may be related to system preferences corruption. You can try deleting your preference files. Go to Finder, select “Go” in the menu, then “Go to Folder,” and type in ~/Library/Preferences/. Look for files that include “com.apple.touchbar” and move them to the Trash. Restart your Mac to create new preference files.
Another potential solution is to check if your Mac account has sufficient privileges to make changes. Sometimes, administrative permissions may be required for certain settings to save correctly. Ensure that you are signed in to an account with admin rights. If the issue continues, consider reinstalling macOS to restore original settings and functionality.
