• Went to upgrade from Catalina to Big Sur.

    Big Sur install fails due to full disk - still allowed installer to run. Sigh.

    Big Sur got far enough to nuke Catalina so no going back (I think)
    Cannot unlock drives with known passwords.
    Recovery keys not working either.
    Suspect Big Sur has caused mismatch in expected auth path.

    New M1 MacBook Pro arrives Monday and I’ve now lost all of my data.

    Fuck Apple updates. This is my second bricked device is as many updates. Last time it was a iMac and it took 2 weeks to figure out recovery.

  • Skimmed through it. What a shitshow.

    Backup kids. Then backup your backups.

  • Spoke to Apple support yesterday. They told me to install Mavericks on a USB drive and boot into that. 🤦🏻‍♂️
    Mavericks doesn’t even support APFS. Ffs.

    Thanks for this article. Sounds like I need to buy a thunderbolt cable in a last ditched attempt to get anywhere.

  • Chris, I love you.

    Great success! Used my old iMac to install a fresh High Sierra install on a USB. Booted from that on my MacBook and we’re away.

    I’d literally been tearing my hair out for days trawling the deepest darkest parts of the web. On the plus side I’m now proficient in diskutil via terminal and also navigation.

    Everything is backing up right now...

    M1 MacBook Pro 16GB lands in the morning too. Ahead of the initial delivery date. I’m not sure I want anything to do with it now tbh.... 😬
