Accessing start up manager on iMac 2021
Good morning all! I'm trying to get into the startup manager in my iMac (24-inch, M1, 2021). I've hooked up the apple keyboard with the cable, and am pressing the OPTION-key at various moments in the startup process. From the moment I see any activity, during the chime, everyting. But the startup manager is nog firing up. Any ideas how I can remedy this?
Many thanks,
Willem
