How to Restart the Touch Bar on a MacBook Pro

If your MacBook Pro Touch Bar is frozen, blank, or showing controls that no longer respond, you can often restart its background process without restarting the entire Mac. The quickest approach is to use Terminal; Activity Monitor offers a graphical alternative. These steps apply only to MacBook Pro models equipped with a Touch Bar.

Method 1: Restart the Touch Bar with Terminal

Terminal can stop the Touch Bar service so macOS can launch it again. You do not need to reinstall macOS or erase any files. Save any work in progress first, then follow these steps.

1. Open Terminal. Press Command-Space to open Spotlight, type Terminal, and press Return. You can also find it in Applications > Utilities.

2. Enter the following command and press Return:

   sudo pkill TouchBarServer

3. If Terminal asks for your Mac login password, enter the password for your administrator account and press Return. Terminal does not display characters as you type the password; that is normal.
4. Wait a few seconds. The Touch Bar may briefly go dark or flicker while macOS restarts the service. Try tapping a control or changing volume to check whether it responds.

The command stops a process by name; macOS is expected to start the service again as needed. If Terminal reports that no matching process was found, or the bar does not recover, move to Activity Monitor rather than repeatedly running commands. Process names and behavior can vary between macOS versions.

Method 2: Restart the Touch Bar in Activity Monitor

If you would rather avoid the command line, Activity Monitor lets you locate the related process and quit it from a window.

1. Open Finder and choose Applications > Utilities > Activity Monitor, or search for Activity Monitor with Spotlight.
2. Select the CPU tab and use the search field to look for TouchBarServer. Depending on your macOS version, a related Touch Bar process may have a slightly different name.
3. Select the matching process, click the Stop (X) button in the toolbar, and choose Quit. If it does not respond to a normal quit, you can choose Force Quit, but avoid terminating unrelated processes.
4. Wait a few seconds and test the Touch Bar again.

Quitting the Touch Bar process should not delete your data, but it may interrupt the controls currently displayed. Do not quit other system processes simply because their names look unfamiliar.

Check the Touch Bar settings

If the bar works but shows the wrong controls—or appears empty rather than frozen—check its configuration before doing more troubleshooting. On supported versions of macOS, open the Apple menu > System Settings > Keyboard, then open Touch Bar Settings. The wording and layout can differ on older macOS releases, where the app is called System Preferences.

Review the option for what the Touch Bar shows, such as app controls, the expanded Control Strip, or function keys. Also check whether the Control Strip is enabled. Available choices depend on your Mac and macOS version. Apple’s guide explains the available options in Change Touch Bar settings on Mac.

If restarting the process does not work

Restart your Mac

A full restart can clear a broader temporary macOS issue. Save your documents, close apps if possible, choose Apple menu > Restart, and test the Touch Bar after signing in again. If the screen is frozen and you cannot use the menu, try to save what you can first; forcing the Mac to shut down can cause unsaved work to be lost.

Install available macOS updates

If the problem returns repeatedly, check System Settings > General > Software Update for compatible updates. Back up important data before a major operating-system upgrade. Avoid deleting system files or following instructions to reinstall macOS as an early troubleshooting step; that is usually unnecessary for a single unresponsive Touch Bar.

Look for signs of a hardware problem

If the Touch Bar remains completely dark after restarting the process and the Mac, or if the issue occurs consistently across apps and user sessions, the cause may not be a temporary software glitch. A normal restart does not repair a failed display or other hardware fault. Arrange an assessment through Apple Support repair options or an Apple Authorized Service Provider, especially if the Mac has suffered a spill, impact, or other physical damage.

Quick troubleshooting checklist

• Try sudo pkill TouchBarServer in Terminal.
• If that does not help, look for the Touch Bar process in Activity Monitor and quit only the matching process.
• Check Touch Bar Settings if the bar is working but displaying unexpected controls.
• Restart the Mac and install compatible macOS updates if the issue persists.
• Seek professional service if the Touch Bar remains dark or repeatedly fails.
