I know that the question can sound suspicius but let me explain. I've installed in end 2015 a frash mac osx. I setted up the firmware password and never used again. Until today. The problem is: I forgot that. I know that I can go to an Apple Store or a certified shop and have it restored, but this requires me a lot of time (I'm far away from Apple Store and the neares shop told me they have to keep it for 10 days beacuse they have other pc to repair first..).
My goal is to reinstall a fresh Mac OSX (I do every year). Is this possible without having the firmware password? I usually do the
Command+R and the proceed from there, but I can't beacuse I don't remember the password.
I was wondering: if I download sierra installation can I run a fresh installation and erase all data?
PS: With the find my phone I can reset pc, but can I also reset the firmware password (I dubpt so)
