How to Modify Apple EFI Firmware Passwords with EFIPW
Apple EFI firmware passwords are used to prevent unauthorized access to the boot options of a Mac computer. They can be set or changed using the Startup Security Utility or Firmware Password Utility on Macs with an Intel processor. However, if you forget your firmware password, you may need to contact AppleCare to reset it, unless you have disabled the reset capability with the firmwarepasswd command-line tool.
EFIPW is a tool that can be used to decode and modify Apple EFI firmware passwords via the command line. It is designed after the non open source OFPW utility and is designed to work on Intel machines running Leopard or newer[^3^]. EFIPW can also disable the reset capability of the firmware password, making it more secure.
To use EFIPW, you need to download it from its website[^3^] and extract it to a folder. Then, you need to boot your Mac from an external drive that has macOS installed and run Terminal. You can use the following commands to use EFIPW:
sudo ./efipw -d: This command will display the current firmware password and its status.
sudo ./efipw -p newpassword: This command will change the firmware password to newpassword.
sudo ./efipw -r: This command will remove the firmware password.
sudo ./efipw -c: This command will check if the reset capability is enabled or disabled.
sudo ./efipw -e: This command will enable the reset capability.
sudo ./efipw -x: This command will disable the reset capability. Note that this is irreversible and you will need to replace the logic board if you forget your password.
EFIPW is a powerful tool that can help you manage your Apple EFI firmware passwords. However, you should use it with caution and make sure you remember your password or have a backup of your data. EFIPW is not supported by Apple and may void your warranty.How to Use FileVault to Encrypt Your Mac's Data
FileVault is a feature of macOS that encrypts your Mac's data with a strong encryption algorithm. FileVault protects your data from unauthorized access if your Mac is lost or stolen. FileVault also prevents anyone from booting your Mac from another disk without your password.
To turn on FileVault, you need to go to System Preferences > Security & Privacy > FileVault and click the Turn On FileVault button. You will be asked to choose how you want to unlock your disk and reset your password in case you forget it. You can use your iCloud account or a recovery key as a backup method. You will also need to restart your Mac to begin the encryption process.
Once FileVault is turned on, you will need to enter your password every time you start up, wake, or log in to your Mac. You can also change your password or turn off FileVault from the same preference pane. However, turning off FileVault will take some time to decrypt your data.
FileVault is a great way to secure your Mac's data and prevent unauthorized access. However, you should always remember your password or have a backup method to unlock your disk. Otherwise, you may lose access to your data permanently. 061ffe29dd
