Overview

• The on-device workflow installs calibration data and re-pairs secure modules so replacement parts meet Apple's reliability and security standards.
• Users will find a Parts & Service prompt in System Settings > General > About that guides a Restart & Finish Repair process.
• Touch ID and Lid Angle sensors can be reused after certain display or logic board repairs, with Touch ID protected by Activation Lock.
• The utility requires macOS Tahoe 26 on an Apple silicon Mac, keeps biometric features disabled until calibration completes, and needs adequate power and connectivity.
• Apple plans to expand access to genuine Mac parts later in 2025 via Genuine Parts Distributors with ordering through MobileSentrix in the U.S. and Europe and Mobileparts.shop in Europe, while some advanced repairs may still require official tools or accounts.
