Hey guys,
im running on a mid-2012 macbook pro retina (os catalina) and i want to make a downgrade (to high sierra) but the bootable pendrive wont appears on Startup Disk options.
to get more complicated, since i bought this mac i never set a firmware password but the lock appears. so, when i make some command (like the recovery mode - cmmd + R) asks for the firmware password.
is there a way to set the startup disk to bootable pendrive on terminal without needs the efi pass?
(choose downgrade to high sierra for the video editing apps and the cuda driver support)
