I noticed that many things may brick the 2018 MacBook Pro because of the T2 chip, and because of lack of information from Apple and proper restore image. I created this wiki post so that people can be informed about what may "brick" the 2018 MacBook Pro. Erasing the hard drive without disabling Secure Boot and allowing External Boot in the Recovery HD first Using the xartutil --erase-all command in the terminal to try and reset Touch ID/Apple Pay. This will delete the contents of the Secure Enclave which includes the decryption keys of your hard drive, rendering it unusable Trying to downgrade from Mojave to High Sierra You did something else that bricked your 2018 MacBook? Add it to the list!
