Catalina and macOS Activation Lock Problem

If a Mac computer user forgot his or her Apple ID or Password and entered incorrect credentials to Catalina macOS login, their computer becomes Activation Locked and can’t be used until the correct Apple ID and password are entered. Some users may think that Mac’s erase or reactivation will help them to unlock their computers. The truth is they are wrong. These actions won’t solve the Activation Lock issue on macOS 10.15 Catalina. Entering the correct Apple ID and password are required to unlock a Mac computer.

The other reason when Activation Lock won’t let you use your Mac on Catalina is when you buy a used computer with Find My Mac on. If a previous owner didn’t disable Activation Lock by turning Find My Mac Off, your computer will display an Activation Lock Screen requiring you to enter the correct Apple ID and password.

macOS 10.15 Catalina and Mac T2 security chip

iCloud Activation Lock works on macOS 10.15 Catalina only on Mac computers with T2 security chips and Find My Mac enabled. The main task of the T2 security chip is securing the following essential features: Activation Lock, Touch ID, secure boot, encrypted data storage and others.

T2 security chip has control over the Catalina booting process by making sure that drivers approved by Apple are installed on a Mac computer. T2 starts its work once you push a power button and finishes it when Catalina desktop is displayed. As a summary, the work T2 chip does is verification to confirm that Apple signed your Catalina OS and bootloader.

Once the verification is complete, you’ll be asked to enter Apple ID and password to unlock the Activation Lock Screen and start using your Mac computer on macOS 10.15 Catalina. If you want to disable Activation Lock on Catalina, you should turn off Find My Mac by entering the correct Apple ID and password.
