"Enter your system lock PIN code to unlock this Mac" error

Post by Paul Pritsis » Tue Jul 25, 2017 4:40 pm

Stumbled acrss an easy way to remove the system lock pin code off of any Macbook, Macbook Pro, Macbook Air, iMac or any other Apple computer. I had a machine that insisted that I enter the 6 digit pin code to unlock it before I could install an OS to it, even if I swapped out the hard drive for a new one. It turns out that the pin code was related to a iCloud lock.

1. You will need a OSX86 (Lion or Snow Leopard) disk aka.
2. Insert the OSX86 disk into your Apple computer.
3. Reboot
4. Hold down the Command + C keys on the Apple keyboard.
5. OSX86 will automatically load Mac OS X setup
6. Click on Utility and select Firmware Password Utility
7. Create a Pin Code then click enable, then save.
8. Go back to Firmware Password Utility enter current pin code
then disable.
9. Reboot Apple Computer
10. No PIN CODE will be present
11. Install MAC OS X as usual

If that doesn't work, also try the following:
