Software tools
Apple Diagnostics can check your Mac for hardware issues.
A System Configuration step may be required at the end of your repair. System Configuration is a postrepair software tool that completes the repair for genuine Apple parts. Running System Configuration has a number of purposes that vary based on the part replaced.
What System Configuration does | Why it's important |
|---|---|
Updates replacement logic board with device serial number | Replacement logic boards must be updated with your device’s serial number to ensure that Apple Pay, FaceTime, iMessage, and iCloud services, such as Find My, can communicate safely and securely with your device. |
Transfers factory calibration values | Certain parts like displays, cameras, and ambient light sensors have calibration values that are customized to each individual part during manufacturing. Transferring these values ensures maximum performance and quality after a repair. |
Links Secure Enclave and biometric authentication parts | After repair of a logic board or a biometric authentication part (Touch ID), linking the biometric sensors to the Secure Enclave on the logic board is required to ensure device security. |
Ensures repair integrity | After a hardware repair, software checks are performed to ensure repair integrity. Repair integrity means that a genuine Apple part has been correctly installed. |
Assigns wireless region | To comply with regional communications regulations, a wireless region must be assigned to your logic board. |
Updates firmware | Keeping firmware up to date ensures that the device has all the latest security and performance features. |
System Configuration requires a strong Wi-Fi network capable of 1.0 Mbps download and upload speeds, with less than 400 ms latency and less than 2% packet loss. Estimated data usage to run System Configuration is 6–22 MB.
The device must be running the latest version of macOS and not a beta version.
