How to Manually Refresh the MacBook Touch Bar

If your MacBook’s Touch Bar is frozen, unresponsive, or showing the wrong controls, you can manually refresh it by killing the Touch Bar system process. In most cases, running a single command in Terminal—pkill TouchBarServer—will restart the Touch Bar and restore normal function within a few seconds. This article explains why the Touch Bar freezes, how to refresh it safely, and what to do if the basic fix doesn’t work.

Why the Touch Bar Freezes

The Touch Bar is controlled by a background process called TouchBarServer, which runs on all MacBook Pro models with a Touch Bar (2016–2023). It handles the dynamic controls, the Esc key, and the system buttons. Like any software, it can occasionally crash or hang, especially after macOS updates, when the system is under heavy load, or after waking from sleep. When this happens, the Touch Bar may show a blank strip, unresponsive buttons, or the wrong app-specific controls.

Refreshing the Touch Bar simply restarts this server process. It does not delete any files, change settings, or affect your Mac’s performance. It is a safe, non-destructive troubleshooting step that Apple support forums commonly recommend.

How to Refresh the Touch Bar (Terminal Method)

The most reliable way to manually refresh the Touch Bar is to use the Terminal app. Here are the exact steps:

Open Terminal (found in Applications → Utilities, or use Spotlight with Cmd+Space and type “Terminal”).
Type or paste the following command and press Return:
pkill TouchBarServer
Wait 3–5 seconds. The Touch Bar will go blank and then reload with the default controls (usually the Esc key, brightness, volume, and Siri).

If the Touch Bar does not return after 10 seconds, try the command again. You can also restart the related process with:

pkill ControlStrip

This resets the Control Strip (the right side of the Touch Bar) independently.

Alternative: Refresh via Activity Monitor

If you prefer a graphical interface, you can use Activity Monitor to quit the Touch Bar process:

Open Activity Monitor (in Applications → Utilities).
Search for TouchBarServer in the search box (top-right).
Select the process and click the X button in the toolbar, then choose Force Quit.
The system will automatically restart the process within a few seconds.

This method achieves the same result as the Terminal command and is useful if you’re already in Activity Monitor for other troubleshooting.

When the Basic Refresh Doesn’t Work

If the Touch Bar is still unresponsive after the refresh, try these steps in order:

Restart your Mac – A full restart clears all system processes and often resolves persistent Touch Bar issues.
Reset the NVRAM (non-volatile random-access memory) – On Intel Macs, shut down, then press and hold Option+Cmd+P+R for 20 seconds during startup. On Apple Silicon Macs, NVRAM reset is not available; instead, update macOS.
Check for macOS updates – Go to System Settings → General → Software Update and install any pending updates. Apple has fixed several Touch Bar bugs in macOS updates.
Check for third-party conflicts – Apps that customize the Touch Bar (like BetterTouchTool) can sometimes interfere. Try quitting them temporarily.

If none of these work, the issue may be hardware-related. Contact Apple Support or visit an Apple Authorized Service Provider for diagnostics.

What the Touch Bar Refresh Does (and Doesn’t Do)

Refreshing the Touch Bar only restarts the software that renders the controls. It does not:

Erase your settings or preferences
Affect your files or apps
Update the Touch Bar firmware (that happens automatically with macOS updates)
Fix physical damage (e.g., a cracked or unresponsive strip)

The Touch Bar hardware itself is not rebooted; only the server process is restarted. This is analogous to quitting and reopening a frozen app.

Preventing Future Touch Bar Freezes

While occasional freezes are normal, you can reduce their frequency:

Keep macOS up to date – Apple regularly patches Touch Bar bugs.
Avoid overloading the system – Running too many resource-heavy apps can cause the Touch Bar to lag.
Quit apps that heavily modify the Touch Bar – These are more likely to cause conflicts.
Restart your Mac periodically – A weekly restart clears cached processes.

If the Touch Bar freezes frequently (e.g., daily), it may indicate a deeper system issue. In that case, consider reinstalling macOS or contacting Apple Support.

Frequently Asked Questions

Will refreshing the Touch Bar delete my custom settings?

No. The refresh only restarts the process; your Touch Bar settings (like which buttons appear in the Control Strip) are stored in system preferences and remain unchanged.

Can I refresh the Touch Bar without Terminal?

Yes. You can use Activity Monitor as described above, or simply restart your Mac. However, the Terminal command is the fastest and most targeted method.

Why is my Touch Bar not showing the Esc key?

If the Esc key is missing, it may be because the current app has replaced it with app-specific controls. Swipe left on the Touch Bar to see the Esc key, or press and hold the Fn key to temporarily show function keys. If the Esc key is still missing after a refresh, check your keyboard settings in System Settings → Keyboard.

Does the Touch Bar work on all MacBooks?

No. The Touch Bar was available on MacBook Pro models from 2016 to 2023. The 13-inch MacBook Pro (2020–2023) and 14/16-inch models (2021–2023) all have it. The MacBook Air never had a Touch Bar.

Is there a way to force the Touch Bar to restart from the keyboard?

There is no built-in keyboard shortcut to restart the Touch Bar. The Terminal command is the standard manual method. If you want a one-click solution, you can create a simple Automator app that runs pkill TouchBarServer, but that requires a bit of setup.

What if my Touch Bar is physically unresponsive?

If the Touch Bar doesn’t respond to touch at all, even after a refresh and restart, it may be a hardware issue. Try resetting the SMC (System Management Controller) on Intel Macs – shut down, then press and hold Shift+Control+Option on the left side and the power button for 10 seconds. On Apple Silicon, the SMC reset is not applicable; contact Apple Support.
