Apple launched its Self Service Repair program in the spring of 2022, giving owners of some iPhones and Macs access to the same parts and repair manuals used by Apple-certified technicians. Since the program's launch, most changes have focused on adding new devices—most recently, support for M1-series desktops in December of 2022. But in a new update today, Apple also announced that it is making the self-repair process slightly less onerous.

The company will now provide a "postrepair software tool" called System Configuration that will handle the process of verifying that repairs were done properly, calibrating and updating the firmware of any replaced components and pairing TouchID and FaceID sensors with the device's Secure Enclave.
