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.

If you want to disable Activation Lock on Catalina, you should turn off Find My Mac by entering the correct Apple ID and password.
