Fog

Archlinux on a macbook. Named after Dean Fog. He's a great magician, but he's also kind of useless.

Install

# MacBook
- macbook, start bootcamp (preinstalled)
  - drag slider for size (deletes apfs snapshots?)

- disk utility
  - create a partition (any format) for your linux install

- restart, holding cmd+r
  - Utilities > Startup Security Utility:
    - [x] No Security
    - [x] Allow booting from external media

- restart, holding opt
  - you don't need to connect to wifi in bootloader
  - boot from EFI

Some strange notes

- you can't modify your HDD's partition scheme outside of macos's diskutil (ex: fdisk/cfdisk)

Wired Install

NOTE:

If issues with outdated archlinux keyring on host,
and host filesystem not writable,
you can copy /etc/pacman.conf to /mnt/pacman.conf,
create an alternate gpgdir or modify SigLevel,
and invoke pacstrap -C /mnt/pacman.conf ....

Wireless Install

NOTE:

despite archiso built yesterday, issues with gpg keys. maybe try the wired iso?

Now follow the official archlinux install instructions, except:

timedatectl set-ntp true

iwctl
 device list
 station wlan0 scan
 station wlan0 get-networks
 station wlan0 connect ${SSID}

ping google.com
pacman -Syy
pacman-key --refresh-keys

mount /dev/nvme1n1p3 /mnt
mkdir -p /mnt/boot/efi
mount /dev/nvme1n1p1 /mnt/boot/efi

pacstrap /mnt base linux-t2 linux-t2-headers linux-t2-docs apple-bcm-wifi-firmware dkms linux-firmware iwd
