Question: “Alt option” won’t work?
Hi so I own an iMac and everytime I switched ignore On I will always see the “no bootable device” screen. I’m well aware that if you press the “alt option” key it’ll be fine and I’ve been doing this for months. But the problem is, three days ago I tried turning it on and press the Alt option and it didn’t work ? I’m quite worried and I can’t find any solutions to this. Any help?
