my mac book air will not allow me to enter a firmware password
I am trying to return my macbook air and am having trouble following the directions to put the computer in the box. After I removed my mac from Find my, I was unable to turn off my firmware password. When I went to Utilities in the menu bar, then choose Startup Security Utility. When I selected the start up security utility, it told me I would have to change my settings with directions. My computer did not respond with the option button and command R as directed. Now, I am stuck
