How can I fix my Mac if I've forgotten the firmware password?
My Macbook Pro went on a kernel panic after failing to install OS X El Capitan. When I try to restore it, the login screen requires a firmware password which I have no memory of setting. Now my device is useless. I know the solution is to go to an Apple Store and have them do their magic. But I live in the Philippines, and the authorized Apple store is clueless on what to do.

Welcome to iMore!
This requires booting into Recovery Mode:
- Reboot your Mac and hold down Command+R to enter recovery mode
- At the Utilities screen, go to the Utilities menu bar item and choose “Firmware Password Utility”
- Select to turn the Firmware Password OFF
If that does not work you can try this:
- Add or remove a stick of RAM. If you have one stick in, add one and if you have two in remove one.
- Power on the Mac and immediately press and hold command-option-P-R.
- The system will restart with the ‘bong' noise; allow it to do this 3 times. After the third one you can let go of the keys.
- Your machine will boot with a cleared password and reset PRAM/NVRAM.
- You can then shut down the machine and reconfigure the RAM as you want it.
If either of these fail I suggest calling Apple and seeing if you can send it in to have them clear it for you as you do not have a store or reseller capable of doing it for you.
