With the new generation Macbook’s, which comes with a T2 Security Chip, each part of the Macbook is matched to work only with the customer’s Macbook. This is a firmware implementation within parts of the Mac such as Keyboards, Screens, Batteries even some of the chips.
During our repair and diagnostic process, we need to cross-test different parts of the customer’s Macbook into our test Macbooks and vice versa to locate the faulty part. Unfortunately, we cannot do this with Macbook’s which are linked to the customer’s iCloud account. As the system sometimes does not detect the replacement part.
We need to ensure that the device is unlocked and removed from your iCloud account, so we can use it’s parts to test across equipment or if the customer want’s us to recycle the equipment securely.
Unlinking the device from the iCloud Account DOES NOT remove its User Password NEITHER allows us to access Customer’s Data.
All Macbooks with a Catalina or above operating system, have their drive encrypted which does not allow anyone to access customer data without their User Account/iCloud Password.
Once the repair is complete, customer can log in to the user account with the original password and sign in to their iCloud Account, which links back the Macbook into their iCloud.
Official Apple procedure is here. We also described it in a step by step details below.
