Instructions for installing Arch Linux side-by-side with OS X on a Macbook Air 2013.
Most of this information was taken from these two sources:
The following example assumes Arch will sit on a single partition; adjust according to preference.
It may also be possible to create a data partition that can be accessed from both OS X and GNU/Linux systems: how to do that properly is left as an exercise to the reader.
mkfs.ext4 /dev/sda5 mkfs.ext4 /dev/sda6 mount /dev/sda6 /mnt mkdir /mnt/boot && mount /dev/sda5 /mnt/boot
If you plan to use any memory-heavy applications (which includes most web browsers), it's a good idea to create either a swap partition or a swapfile for system stability. Swapfiles are easier to resize or remove if you change your mind, so we'll create a 512M one:
dd if=/dev/zero of=/mnt/swapfile bs=1M count=512 chmod 600 /mnt/swapfile mkswap /mnt/swapfile
This requires an internet connection. Options:
Wired (with some Apple proprietary ethernet thing ($$$?
Wireless (requires b43 wireless firmware (AUR))
pacstrap /mnt base base-devel genfstab -U -p /mnt >> /mnt/etc/fstab
/dev/sda6 / ext4 defaults,noatime,discard,data=writeback 0 1 /dev/sda5 /boot ext4 defaults,relatime,stripe=4 0 2 /swapfile none swap defaults 0 0
arch-chroot /mnt /bin/bash passwd echo myhostname > /etc/hostname ln -s /usr/share/zoneinfo/America/Sao_Paulo /etc/localtime hwclock --systohc --utc useradd -m -g users -G wheel -s /bin/bash myusername passwd myusername pacman -S sudo
echo "%wheel ALL=(ALL) ALL" > /etc/sudoers.d/10-grant-wheel-group
locale-gen echo LANG=en_US.UTF-8 > /etc/locale.conf export LANG=en_US.UTF-8
Insert "keyboard" after "autodetect" if it's not already there.
Then run it:
mkinitcpio -p linux
To boot up the computer we will continue to use Apple's EFI bootloader, so we need GRUB-EFI:
pacman -S grub-efi-x86_64
Aside from setting the quiet and rootflags kernel parameters, a special parameter must be set to avoid system (CPU/IO) hangs related to ATA, as per this thread:
GRUB_CMDLINE_LINUX_DEFAULT="quiet rootflags=data=writeback libata.force=1:noncq"
Additionally, the grub template is broken and requires this adjustment:
# fix broken grub.cfg gen GRUB_DISABLE_SUBMENU=y
grub-mkconfig -o boot/grub/grub.cfg grub-mkstandalone -o boot.efi -d usr/lib/grub/x86_64-efi -O x86_64-efi --compress=xz boot/grub/grub.cfg
Copy boot.efi (generated in the command above) to a USB stick for use later in OS X.
Exit everything and reboot into OS X (by holding alt/option) and then choosing it.
exit # exit chroot reboot
Format ("Erase") /dev/sda4 using Mac journaled filesystem
This procedure allows the Apple bootloader to see our Arch Linux system and present it as the default boot option.
cd /Volumes/disk0s4 mkdir System mach_kernel cd System mkdir Library cd Library mkdir CoreServices cd CoreServices touch SystemVersion.plist
ProductBuildVersion ProductName Linux ProductVersion Arch Linux
Copy boot.efi from your USB stick to this CoreServices directory. The tree should look like this:
|___mach_kernel |___System | |___Library | |___CoreServices | |___SystemVersion.plist |___boot.efi
sudo bless --device /dev/disk0s4 --setBoot
You may need to disable the System Integrity Projection of OS X:
Restart the computer, while booting hold down Command-R to boot into recovery mode.
Once booted, navigate to the “Utilities > Terminal” in the top menu bar.
Enter "csrutil disable" in the terminal window and hit the return key.
Restart the machine and System Integrity Protection will now be disabled.
Voila, Arch Linux is installed.
Reboot the computer and hold the alt/option key to select which operating system to boot.
(Make sure that b43 and ssb modules are not present in the output from `lsmod`)
…so that kernel updates don't leave you without wifi. DKMS is a service that recompiles external modules after every kernel upgrade.
sudo pacman -S dkms sudo systemctl enable dkms.service
sudo pacman -S dialog sudo wifi-menu -o
The tilde key does not work on the keyboard out of the box. There are several solutions listed here but this one worked for me:
sudo nano /etc/modprobe.d/hid_apple.conf
options hid_apple iso_layout=0
The <insert> key can be reproduced with fn+<Enter>. So to paste in an xterm window for instance, use S-fn-<Enter>.
F1-F12 require fn+<F1>, etc.
Out-of-the-box battery performance on Arch Linux should be good and at least comparable to OS X.
If you want to try to improve battery life, there are two recommended packages documented in the ArchWiki:
There are other folks who have blogged about this process since I started this:
