These notes are a supplement to the official manual on the Arch Wiki: Mac. Overall I am very happy with the setup and currently use it as my primary system.
Partitioning from Mac OS X
recover mode (
CMD+R when rebooting your
mac) to partition the disk. If you use
Filevault, make sure
off before partitioning..
Reboot and press
cmd + R to enter recover mode. Select
and find your SSD. I had to first run
first aid on the disk as there
were some minor corruptions. Next partition the disk by pressing
create a new partition.
For my first experiment I created a single 46GB partition. This worked
fine, but for a good setup you need to seperate the
OS from the
folder and have a seperate
swap partition for
my second go I create 3 partitions.
swap: 16GB (same as mem) /dev/sda6 root: 15GB /dev/sda5 home: 100GB /dev/sda4
Note from the 1st experiment: the manual says to skip partitioning in
the installer and only do the formatting from there. This means, I
guess, that if you want to have a seperate home partition you need to
create it now and not dusing installation. As I created only 1
partition this also means I will not use a swap partition and I ended
up using a
Boot from USB
Use the ISO to create your own bootable medium, boot from it. I used Etcher to create the bootable USB disk.
View disk partitioning
lsblk command to see the layout of the disks on the machine.
In my case
/dev/sdb is th USB drive and
/dev/sda is the main SSD.
On the main SSD the
/dev/sda1 is the
ESP used to hold the
Apple Cinema LED
My 27" monitor is working nicely with the console, it just doesn't show all the lines at the bottom. So much space, but still it fails. At least it immediately mirrored the display using the thunderbolt cable, that makes me happy.
Reading reddit I found a reference to a larger font for high res screens.
For me the
US keyboard layout as well as the console font are good,
could do with a bigger font, but I did not figure out how to do this
from the bootable medium. It seems you will need to download a seperate
console font for this to work.
I booted using a wired conncetion, it just works out of the box. To start from a wireless you need to do some additional work, it is explained on the wiki.
timedatectl to connect to the
NTP service went without a
hitch, the timezone is set incorrectly though. I used
set the timezone to CET.
timedatectl set-timezone CET
The partitions I already created from macOS now need to be formatted.
mkds.ext4 /dev/sda4 mkds.ext4 /dev/sda5 mkswap /dev/sda6 swapon /dev/sda6
The I mounted the disk to
/mnt and the ESP boot partition to
mount /dev/sda5 /mnt mkdir /mnt/boot mount /dev/sda1 /mnt/boot mkdir /mnt/home mount /dev/sda4 /mnt/home
rankmirrors, lets find the top 6 mirrors that I can use for
installation. This takes a little while.
/etc/pacman.d/mirrorlist /etc/pacman.d/mirrorlist.backup rankmirrors -n 6 /etc/pacman.d/mirrorlist.backup > /etc/pacman.d/mirrorlist
Remember to update the pacman database using
pacman -Syyu after
selecting new mirrors. Select
n if pacman wants to update stuff. I am
unsure if this is actually required for the bootstrap/pacstrap stage.
Install the base system
pacstrap to install the basic operating system.
pacstrap /mnt base
I choose to only do the base system for now, to get up and running.
chroot or the actual reboot into the live system I will add
the packages I require such as
Generate a new
fstab from the mounts.
genfstab -U /mnt >> /mnt/etc/fstab
It will find the root partition and the boot partition.
arch-chroot we will activate our installed base system for
ln -sf /usr/share/zoneinfo/Europe/Amsterdam /etc/localtime
And sync the hardware clock to our new zone
en_US.UTF-8 UTF-8 in
/etc/locale.gen and rand
/etc/locale.conf set this to the default
Create the file
/etc/hostname and put your hostname in it. I chose
archman as a play on
ant-man, to go with my superhero themed
Currently (april 2017) there is a bug in the kernel that makes the system not suspend/hibernate well. There is a custom kernel we can use (its like it is 1999 all over again!).
yaourt, by adding the repo to
[archlinuxfr] SigLevel = Never Server = http://repo.archlinux.fr/$arch
Yaout to perform AUR package management.
pacman -Sy pacman -S yaourt
Install the build utils and the custom kernel.
pacman -S base-devel yaourt -S linux-macbook
This will take some time as it will download and compile the patched kernel.
I tried both rEFInd and Grub, they did not work nicely.
pacman -S refind-efi efibootmgr
I installed refind-efi and ran
refind-installto get a proper bootmanager instead of having to press
altat every boot.
Grub is not useful
This is the truly exciting part, my first EFI bootmanager thingy. First install the packages
pacman -S grub efibootmgr
Now we need to install GRUB to
grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=grub
pacman -S intel-ucode
Enable the microcode by regenrating the GRUB config file.
grub-mkconfig -o /boot/grub/grub.cfg
Second attempt systemd
bootctl you can easily use the systemd bootmanager.
bootctl --path=/boot install
/boot/loader/loader.conf to automatically load our
#timeout 3 default arch timeout 4 editor 0
Next, create a file called
/boot/loader/entries/arch.conf to hold the
Arch boot configuration. Note that I did install the
package as suggested in the manual.
title Arch Linux linux /vmlinuz-linux-macbook initrd /intel-ucode.img initrd /initramfs-linux-macbook.img options root=/dev/sda5 rw elevator=deadline quiet splash resume=/dev/sda6 nmi_watchdog=0 i915.semaphores=1 intel_idle.max_cstate=1
exit the shell and return to the USB boot shell.
unmount -R /mnt to
unmount all disks. Then
reboot and pray.
Verify MAC still works
First boot, directly into linux, this was somewhat unexpected. Where did mac go?
ALT during boot showed th eboot disk and allows booting into
Mac again. The setup still works, but GRUB has become the main
bootloader and boots into Arch.
Verify we can boot into linux
Restart and just let it run will now boot into linux. I would want a choice between the 2, this is somewhat unexexpected.
Use an unprivileged user
sudo to allow unprivileged users to perform administrative
pacman -S sudo
Create unprivileged user in users en wheel group.
useradd -g users -G wheel,input -s /bin/bash arjenw
Lock the root account.
passwd -l root
A graphical user interface
To get the graphics card working the manual suggests to use the xf86-video-intel driver. I found that it causes a lot of tearing/flickering when recording with OBS (Open Broadcast Studio) and my system would freeze up completely from time to time.
The alternative is to ditch the xf86-video-intel driver. Apparently
the driver is buggy and it has not been updated in a long time. If you
do not set install a driver it will default to the
DDX driver, which is quite high performant already. So I went with
Install Xorg as a base
pacman -S xorg-server
Install gdm gnome gnome-extra
pacman -S gdm gnome gnome-extra
I disabled WayLand in
/etc/gdm/custom.conf in order to use OBS
Start GDM by default
systemctl enable gdm
systemctl start gdm
Install and enable NetworkManager to manage the network connections.
pacman -S networkmanager systemctl enable NetworkManager systemctl start NetworkManager
Enable bluetooth, start it. My apple mouse now works in Gnome.
systemctl enable bluetooth systemctl start bluetooth
Apple Mouse scrolling
Note: with kernel 4.10.10-1-macbook I experienced a lot of lock-ups,
these seem to be due to the apple mouse. If it happens to you check the
last journal with
journalctl --boot -1 to check the last boot logs.
Some of the times it will list the crash for
hid_magicmouse. I just
switched to a plain old wired mouse instead.
I use a bluetooth based
Apple Magic Mouse. I quite like it, but the
scrolling needs to be fast. By default there is little in the means of
setting up scrolling in the GUIs.
The mouse is driven by the
hid_magicmouse kernel module which takes
several parameters. You can view the parameters by looking at the
parameters set in
emulate_3button N emulate_scroll_wheel Y report_undeciphered N scroll_acceleration Y scroll_speed 55
I created a modprobe config in =/etc/modprobe.d/magicmouse.conf with the following contents:
options hid_magicmouse scroll-speed=55 scroll-acceleration=1 emulate_3button=0
USB Mouse disconnects/freeze
With the wired mouse I experience a lot of choppy movement, freezing of
the cursor. This is due to the rigid powersaving settings that I have
tlp. Basically it toggles the
auto-suspend on the USB ports to be as fast as possible to conserve
energy. Very good on its own, but it results in choppy behaviour.
For now I have just toggled the setting using the powertop tool. Run
sudo powertop, press TAB to go to the tunables and press enter on the
Autosuspend for USB device USB Optical Mouse [USB MOUSE].
For instructions to automatically fix this on boot see this wiki page. When I implement it myself I will update this section further.
tlp to manage the performance of the laptop when on power
and on battery. So far it seems to pull quite a time from a single
charge, so I am happy with that.
yaourt -S tlp sudo systemctl enable tlp sudo systemctl enable tlp-sleep sudo tlp start
When you upgrade your software, there's a certain way you need to do it! Primarily you need to use yaourt to do it:
To refetch and recompile all git software, you need to do:
yaourt -Syua --devel
But beware! If you reinstall your kernel, you need to rebuild it:
sudo mkinitcpio -p linux
