Bypass Mac Firmware Password

1) Shut down your computer

2) Remove the battery

3) Slide one of the levers (it doesnt matter which one) to the left. This will release the RAM

4) Gently wiggle the RAM card out and put it aside, you will put it back later

5) Boot up the computer while holding COMMAND+OPTION+P+R (this resets the parameter ram)

6) Wait for the startup chime to sound 3 times

7) Release the keys and shutdown the machine once you reach the login screen

Replace the RAM module and slide the lever back while pushing it in until it does not wiggle anymore

9) Now if you boot up the machine you should bypass the Mac firmware password.

You can now use the machine as usual, boot from an external drive, or whatever else.
