    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...

    I recently bought a PowerBook G4 15“ to fix it. After boot it first shows an icon with a world globe. Then it turns into a folder that is switching between MacOs face and a question mark. See pics attached. Can you tell what it is and how to fix that? Is OS missing maybe the drive is broken?

    MP 1,1-5,1 OCLP 1.4.2 MP 5,1. Issues at boot picker and keyboard issues e.g. CAPS LOCK and repeat

    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...

    What does it mean when the installer said, “The sampled color is not equal to the first color, this isn't an Apple logo boot image” during install?

    MP 1,1-5,1 SLED positions left to right — 1, 2, 3, 4

    Curious as to whether the position of HD/SSD sleds makes any difference between slots one, two, three or four? The presence of a non-bootable—and also unrecognised 8TB HD—in the left-most position, on start-up appeared to prevent the machine from advancing beyond the chime, despite the presence...

    Boot issue

    While I guess I’m not completely computer illiterate, as I get older it feels like I’m not far from it. Always before, when I’ve had problems I’ve been able to come here and, after some searching, find the answer to my problem. This time, maybe because I got frustrated, I didn’t think to come...

    MP 7,1 Slow boot when adding more drives?

    I tried Googling this but only get generic answers or solutions to different problems. I recently reacquired a Mac Pro (7,1) and it worked well initially. When I added 2x spinning disks and a SATA ssd using a sonnet J3i, it takes a long time to boot. The spinning indicator spins for 3-4...
