Introdução
Use this guide to replace the Touch ID sensor/power button in your MacBook Air 15" 2024.
You may need to replace the Touch ID sensor/power button if it's unresponsive, inconsistent, or physically damaged.
To maintain Touch ID functionality, you must also replace your logic board with a new one that's paired to the replacement Touch ID sensor. The MacBook Air's original Touch ID sensor is uniquely paired to the logic board at the factory. Without Apple’s proprietary calibration process, even a genuine replacement logic board from another MacBook Air won’t work.
