One significant improvement is that customers no longer need to contact Apple to complete their repairs. The System Configuration tool, responsible for verifying and authenticating fixes with official parts, can now be accessed by putting the device into Diagnostics mode and following the provided instructions. While Apple staff will still be available if assistance is required, their involvement is now optional. The System Configuration tool plays a crucial role in ensuring a fully functional device as it not only calibrates components but also connects biometrics like Face ID and Touch ID to the Secure Enclave.
