I just bought a new iMac and I can not use it.
When I turned it on, the brightness was set to 0%, so I can not see anything on the screen even if the computer is running normally.
I can talk about it, and it will read me the displayed text, so I know I’m in the setup menu where I have to select my country. I can find my country on the list by clicking the down arrow button and listening to Voice Over, but idk how can I move past this point because it does not matter to click Enter after selecting my country.
I tried using the F1 / F2 buttons to light up the screen, but they do not work. I read that these buttons do not work until you are past the login screen. Any help?
