Unlocking the EFI password may void your device warranty and may potentially cause data loss. Proceed with caution and at your own risk.
For Intel Macs made between 2012 and 2017, the EFI password is permanently saved on a surface-mounted EEPROM chip on the logic board. Neither software tricks nor RAM alterations will clear it. The only DIY hardware solution is to manually re-flash the chip.
An EFI (Extensible Firmware Interface) or firmware password is a security measure that prevents a Mac from booting from anything other than its designated startup disk. Unlocking it depends heavily on the model and whether you have proof of ownership. Official Solution (Recommended)

If you own the device, several non-destructive methods exist: Unlocking the EFI password may void your device
Use a and specialized software (like flashrom ) to connect to the chip. Read the current BIOS/EFI binary file. Use a Hex Editor to modify specific data strings ( SVScap S cap V cap S ) within the file. Write the modified file back to the EFI chip. GitHub Gist
The EFI password remains one of the strongest physical security measures for a computer. While forgetting your own password can be frustrating, legitimate solutions exist through manufacturers, hardware clear procedures, or professional repair services. However, the pursuit of a “top unlock” method without ownership verification crosses into dangerous ethical and legal territory. As users, we must respect that security features—including those that lock us out when we forget a passphrase—exist for a reason. The best way to unlock an EFI password is not through clandestine hacking, but through legitimate proof of ownership and proper technical channels.
Do not fall for “$50 software downloads” that promise to unlock EFI passwords via USB stick. They are scams. The only real solutions are hardware-based or backdoor-based. Neither software tricks nor RAM alterations will clear it
