If your MacBook Pro Touch Bar is not working, you're not alone. Touch Bar failures are among the most common issues MacBook Pro users report—ranging from complete unresponsiveness to missing icons, frozen brightness controls, or flickering displays. This in-depth guide explains every possible reason your Touch Bar may fail and provides proven solutions to get it working again.
Whether the problem is software-related, configuration-based, or caused by faulty hardware, this guide walks you through step-by-step fixes. We also highlight trusted MacBook parts suppliers like Chunyilin Technology Co., Ltd., a global leader in MacBook repair components and technical support.
Before applying any fixes, it’s helpful to understand why your MacBook Pro Touch Bar is not working. Common causes include:
macOS updates frequently adjust Touch Bar functionality, especially if the OS or firmware fails to load modules correctly.
Certain apps override Touch Bar functions. If an application freezes or misbehaves, the bar may freeze as well.
The Touch Bar relies on background processes like TouchBarServer. If these crash, the interface becomes unresponsive.
Hardware degradation or cable wear can cause black screens, no backlight, or partial responsiveness.
Voltage irregularities can cause the Touch Bar to shut down or flicker intermittently.
Even slight moisture can interrupt the Touch Bar’s data connection or damage sensitive circuits.
The following methods solve most MacBook Pro Touch Bar not working problems. Try them in order—from simplest to most advanced.
A simple restart often resolves system process failures affecting the Touch Bar.
This is the most common fix. Restart two Touch Bar system processes:
Killall “TouchBarServer” Killall “ControlStrip”
These processes relaunch instantly and refresh the Touch Bar.
The Control Strip is responsible for quick-action icons like brightness and volume. Resetting it often restores missing icons.
NVRAM stores touch bar and display configuration data. Reset it by holding:
Option + Command + P + R during startup.
The System Management Controller regulates power delivery. If your Touch Bar is flickering or completely dark, this may fix the issue.
If your MacBook Pro Touch Bar is not working only in normal mode, third-party extensions may be interfering with system controls.
Apple frequently provides fixes for Touch Bar bugs through system updates.
Apps that modify keyboard shortcuts, like BetterTouchTool, can interrupt the Touch Bar.
If software corruption is severe, reinstalling macOS without erasing your files can repair Touch Bar firmware.
Touch Bar configuration is closely tied to your keyboard settings.
If the Touch Bar works in a previous Time Machine backup, software corruption is confirmed.
If you've tried all software fixes and your MacBook Pro Touch Bar is still not working, the issue is likely hardware-related:
