If you’re still in two minds about efi unlock and are thinking about choosing a similar product, AliExpress is a great place to compare prices and sellers.If you have the a 2011 Macbook, the PRAM / NVRAM wipe could work for you too, but you have to do it on your own risk. For security reasons I recommend to reset your password and activate two-factor authentication. The receipt proofs that you are the owner the device, so the Apple Store is able to unlock it.
