my dad gave me a macBook pro model a1425 … so long ago he did not use the macbook so he forgot his firmware password (EFI) so I can open the macbook I need the password. Someone helps me to overcome this password please

There’s no way to overcome an Efi password lock without getting into low level Efi programming and you’ll need appropriate hardware and knowledge. You would need investing money and unless you’re skilled in firmware coding quite some time and study to understand what needs to be done. Chances to brick your Mac would be present in any case. It’s not a simple job, Apple invests valuable resources into protecting safety & security.

apple not gonna help unless you have proof of purchase and then even so they will try to get you to trade it in to buy a new one and give you pennies in return. as far as fixing it yourself I don’t recommend unless you really have knowledge of electrical engineering and experience with removing and soldering ic chips. the easiest thing to do for a basic DIY do it yourself with some skill is to just swap out the motherboard with a clean unlocked one might cost you a few hundred but thats way better than ending up with a expensive doorstop i would estimate 300-400 tops with good local guy. don’t even bother with apple all their boards seem to be 900-1000 when you ask them. Just another ploy to get you to buy a new one.
