Is it possible to boot from Internal SSD? #18

After T2 patch, Is it possible to boot from Internal SSD?

Redecorating commented 2 years ago

It's possible on both normal linux kernels and T2 linux kernels.

To boot linux from the internal ssd you need to have secure boot turned off, and a kernel version greater than 5.4, which will include quirks for the T2 SSD controller. These quirks are already in upstream kernels, which is why it works with upstream kernels.

There was error to clean install ubuntu to mac mini 2018 (T2) unable to install grub-install /dev/nvme0n1 failed

Any workaround?

You are using an official Ubuntu ISO, which won't work. Try using https://github.com/AdityaGarg8/mbp-ubuntu/releases/tag/v20.04-5.17.1

I can execute grub-install with official 22.04 iso

sudo -s mount /dev/nvme0n1p2 /mnt mount /dev/nvme0n1p1 /mnt/boot/efi for i in /dev /dev/pts /proc /sys /run; do sudo mount -B $i /mnt$i; done sudo chroot /mnt grub-install --force /dev/nvme0n1 update-grub
