    iPhone 16 Pro max 'bricked'

    Why is rebooting to a different partition so difficult on M1 macs?

    I don't get it. Why can't I just hold Option like I used to? Now I can't even hit restart, no, I need to hold down the power button until it shuts off, hold it down until it turns back on again, keep holding it forever, until finally it gives me the menu. Then of course we can't just be done...

    In my MP 5,1 has 3 boot drives with: Ventura, Monterey, Linux/Ubuntu. I chose this setup so if I somehow "ruined" one of the disk I would still have a bootable system. Also it should allow me to upgrade the Monterey to Sonoma and if that turns out to be a disaster I should be able to fall back...
