[flashrom] Efi password lost iMac27

[mustapha.rafik]

Hello, 
I have lost the password of my imac27 looking a way to reset it. I found a link to a tutorial using a bus pirate and a flashrom. I am not sure I can do it by myself. I am far from being a specialist of computing and electronics. Do you have explanations on how to do it? Is it simple for a beginner?

Thank you in advance,
Regards
