Macbook Pro 2014 firmware password HELP

Sure. Take you MBPro to an Apple-authorized service provider - one that can do warranty work with Apple products that they sell. They can't clear the password, either, but will call Apple tech support, who CAN clear your password.

If you had an older MBPro (older than a 2011 model, for example), then there is some easy steps to clear a firmware password.
Apple prevents that now, to make the systems more secure. You can't clear an EFI firmware password on your own.

Oh, don't forget that you have to show proof of ownership. Don't know if something from a pawn shop will be good enough for that proof, but all you can do is ask, eh?

 

The pawnshop probably sold it "cheap" because they realized that they'd bought stolen property and wanted to get rid of it.

"Proof of ownership" from a pawn shop ain't gonna help you with Apple.

The way I see it, you have 4 choices:
1. Take it to an Apple genius bar and see if they'll help
2. If they won't, try an "ebay solution"
3. Put it in the closet and forget about it.
4. Sell it "for parts".

 

Apple will only unlock a FW PW if you are the original purchaser of the machine. I do not trust those bay solutions because you will likely need to send the machine off or trust a guy (somewhere) with your machine information. You have a very pretty paper weight. Replace the logic board, part it out, or return the machine.
