Just to clarify: MacBook laptops do not have a touch screen — none of the MacBook Air or MacBook Pro models, even the latest ones, come with touch-enabled displays.
If you’re referring to the Touch Bar (the thin touch strip above the keyboard on some MacBook Pro models), and it’s not working, here’s how you can troubleshoot that:
✅ Fix 1: Restart the Touch Bar process
- Open Terminal (Applications → Utilities → Terminal).
- Run this command:
sudo pkill TouchBarServer - Then run:
sudo killall ControlStrip
The Touch Bar should restart automatically.
✅ Fix 2: Reset the SMC (System Management Controller)
- Shut down your Mac.
- Hold Shift + Control + Option on the left side + Power button for 10 seconds.
- Release all keys and turn on the Mac.
✅ Fix 3: Reset the NVRAM
- Shut down the Mac.
- Turn it on and immediately hold:
Option + Command + P + R - Keep holding for ~20 seconds, then release.
✅ Fix 4: Update macOS
- Go to Apple menu → System Preferences → Software Update
- Install any available macOS updates.
❗ If you mean touch screen support in general (like on Windows laptops):
Unfortunately, MacBooks do not support touch screen. If you need touch input, consider using:
- An iPad + Sidecar (turns iPad into a second screen with touch/Apple Pencil).
- A third-party touch screen monitor compatible with macOS.
If you tell me exactly what model you have and what you mean by “touch screen,” I can help you more precisely — want to describe the issue a bit more?
