How to Fix Touch Bar Not Working in macOS Tahoe 26

The Touch Bar on MacBook Pro gives quick access to shortcuts, media controls, and function keys, making daily tasks faster. After updating to macOS Tahoe 26, some users notice the Touch Bar becomes unresponsive, flickers, or disappears.

Most of the time, this is software-related—temporary glitches, stuck system processes, or conflicting apps. Below are five practical solutions, each explained in detail so you can restore your Touch Bar quickly.

How to Restart Your Mac

It might seem simple, but restarting your Mac often resolves Touch Bar freezes. This clears temporary caches and restarts the system processes that control the Touch Bar.

Tip: If the Touch Bar still doesn’t respond, try a forced restart. Hold the Power button until the Mac shuts off, then press it again to turn it back on. This clears deeper memory conflicts

1. Relaunch Touch Bar Processes

Sometimes the Touch Bar stops working because the background processes that power it—TouchBarServer and ControlStrip—have crashed or stalled. Restarting these processes can reload the Touch Bar without restarting your whole Mac.

1. Open Terminal (Applications → Utilities).
2. Type the following commands, pressing Enter after each:

sudo pkill TouchBarServer
sudo killall ControlStrip

3. The Touch Bar will disappear briefly and then reload automatically.

Alternative: Open Activity Monitor, find TouchBarServer and ControlStrip, and quit them manually. The system will restart them automatically.

2. Boot in Safe Mode

Safe Mode prevents non-essential apps and processes from running, clearing cached system data that can interfere with the Touch Bar. This method is useful if a software conflict is causing repeated issues.

Apple Silicon Macs:

1. Shut down your Mac.
2. Hold the Power button until startup options appear.
3. Select your startup disk while holding Shift.
4. Click Continue in Safe Mode.

Intel Macs:

1. Power on your Mac.
2. Immediately hold Shift until the login screen appears.
3. Use your Mac normally in Safe Mode for a few minutes, then restart it normally to exit Safe Mode.

3. Reset SMC and NVRAM (Intel Macs Only)

The System Management Controller (SMC) and NVRAM manage low-level hardware functions, including the Touch Bar. Resetting them can resolve unresponsive or flickering Touch Bar issues.

1. Shut down your Mac completely.
2. Press Option + Command + P + R simultaneously and hold for ~20 seconds.
3. Release the keys after the Apple logo appears twice.
4. Allow your Mac to finish booting and check the Touch Bar.

Tip: Resetting NVRAM and SMC does not delete personal files—it only refreshes system-level settings like volume, display, and Touch Bar behavior.

4. Reinstall macOS Tahoe

If all else fails, corrupted system files might be preventing the Touch Bar from working. Reinstalling macOS Tahoe can restore these files without erasing your data.

1. Back up your Mac to Time Machine or another backup method.
2. Open System Settings → General → Software Update → Reinstall macOS Tahoe.
3. Follow the on-screen instructions to reinstall macOS.

Alternative Methods

• Check Keyboard & Touch Bar Settings: System Settings → Keyboard → Touch Bar → Ensure “Expanded Control Strip” or “App Controls” is selected.
• Remove Conflicting Apps: Uninstall or update apps installed recently that might modify macOS interface.
• Re-add Email Accounts: If apps like Mail are affected, remove and re-add accounts using guides like iPad Email Setup or Mac Email Setup.
