how to reset the mbp firmware password?
hi, i have my mbp mid 2012 model purchase quite many years back. i am now required to key in firmware password, which i had forgotten. i sent to apple service centre, which informed that in order to get the password reset, i need to have the purchased receipt for ref only than can the password be reset. but unfortunately i have lost the receipt as this is quite many years back. any idea how to get this resolved?
