Some technicians prefer to completely desolder the existing EFI chip using a hot-air rework station. They then solder a brand-new, pre-programmed EFI chip onto the logic board. This completely wipes the old settings, including the password lock. 5. Software Tools and Firmware Dumps If the device is Activation Locked and you

For modern Macs built with (M1, M2, M3, M4 families) or the Intel T2 Security Chip (2018–2020 models), a secondary Mac can be leveraged to wipe the device and clear security restrictions.
