This guide outlines a more recent walkthrough to install and configure Arch on the more recent Macbook 9,x (Mid-2012) hardware alongside a pre-existing OSX operating system. This requires adequate free disk space, install media (such as a USB or CD), and a wired connection for the initial steps of the install procedure.

This article does not cover how to replace OSX with Arch, though there are not many extra steps necessary to do so.

For general help on the install preocedure see the Beginners' Guide

Note: Remember to back up your pre-existing OSX installation before proceeding!

Preparation

Recording UIDs

If you want to access your OSX user directories from Linux, write down the UID and GID for the users.

Note: OSX begins with the first user's UID at 501 while Arch defaults to 1000.
Warning: Never, ever change any file permissions in your OSX partition from Linux. Doing so can and will lead to serious repercussions.

Install Boot Manager

Optional. The easiest way to begin is by installing rEFInd on Mac OSX before moving on to Arch. This will place a boot menu on startup. The config will be in your OSX partition - if this is not desirable it is possible to install it later in Arch. For more information consult UEFI.

Shrinking Macintosh HD

Boot Camp now requires a Windows installation disc before altering partitions, but it is possible to do this using Mac OSX's disk utility. Create a new partition, calculate the amount of free space required for all new partitions and shrink Macintosh HD to match this amount. Leave the new partition as free space.

Installation

Preparing Installation Media

Download Arch and burn it to a USB, CD or DVD, and boot into the Arch install.

Running the Arch Installation

Proceed from the Installation section in either Beginners' Guide/Installation or Installation Guide#Installation. Note that you'll need a wired connection to continue for now.

The following differences will apply to MacBooks:

Sample partition layout

partition  mountpoint  size       type  label
/dev/sda1  /boot/efi   200MiB     vfat  EFI
/dev/sda2  -           ?          hfs+  Mac OS X
/dev/sda3  -           ?          hfs+  Recovery
/dev/sda4  -           100MiB     hfs+  Boot Arch Linux from the Apple boot loader (optional)
/dev/sda5  /boot       100MiB     boot  boot
/dev/sda6  -           ?          swap  swap (optional)
/dev/sda7  /           10GiB      ext4  root
/dev/sda8  /home       remaining  ext4  home

Install Bootloader

Use GRUB2#UEFI_systems_2 for more information.

After setting up the base system, do the following in your chrooted environment:

# pacman -S grub-efi-x86_64

# mkdir -p /boot/efi
# mount -t vfat /dev/sda1 /boot/efi

# modprobe dm-mod
# grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=arch_grub --recheck --debug
# mkdir -p /boot/grub/locale
# cp /usr/share/locale/en\@quot/LC_MESSAGES/grub.mo /boot/grub/locale/en.mo


Post Installation

Continue with Beginners' Guide/Post-installation or Installation Guide#Post-installation, noting the following modifications:

Users

If you wrote down your OSX uid's and gid's eariler, new users can be created by running:

# useradd -m -u [uid] -g [gid] -G [additional_groups] -s [login_shell] [username]

In order to be able to access a OSX user's directory, only id's need to match.

Wireless

Macbooks 8,1 to 9,2 (and possibly newer) use BCM4331 for Wifi. Linux Kernel 3.3 has led to a loss of most of the functionality - however, as of March 2013 bleeding-edge patches are available that improve the situation significantly. base-devel is required.

$ curl -O https://www.kernel.org/pub/linux/kernel/projects/backports/2013/03/28/compat-drivers-2013-03-28-5.tar.bz2
$ tar xjf compat-drivers-2013-03-28-5.tar.bz2
$ cd compat-drivers-2013-03-28-5

$ scripts/driver-select b43
$ make
$ sudo make install

Create /etc/modules-load.d/b43.conf and write b43 to load wireless at startup.

Install b43-firmwareAUR from AUR and reboot. From here on in, wifi configuration should proceed normally - once it's working the wired connection may be disconnected.

Note: Since this is a bleeding-edge fix, it's probably a good idea to keep a wired connection handy in case something goes horribly wrong.

Xorg

Main Page: Xorg

Install xf86-video-intel and setup Xorg as you normally would.

The built-in keyboard and most usb input devices will work out-of-the-box, but xf86-input-synaptics is needed in order to use the built-in touchpad.

Bells & Whistles

Emulating OSX Touchpad Gestures

With a little bit of work it's possible to tweak the multitouch options on the track.

Using synclient

synclient is included with the xf86-input-synaptics driver. It is useful for experimenting with settings as they take effect immediately and expire at the end of an X session. Many OSX options can be emulated without any additional software.

Run synclient -l to have a look at all the available options. Here are some OSX-like suggestions:

  • By default synaptics is configured to use a double-tap drag gesture found on older touchpads - one may argue that this is not necessary on a clickpad. synclient TapAndDragGesture will turn this off.
  • TapButtonX and ClickFingerX sets the mouse button triggered by tapping or clicking with X fingers. set TapButton2=3 and ClickFinger2=3 to assign two-finger click to the right mouse button.
  • Setting the bottom-right corner click to right mouse button can be done by subtracting about 500 from RightEdge and BottomEdge and plugging the new values into RightButtonAreaLeft and RightButtonAreaTop. If the last two options are not visible, set Clickpad=1.

To make settings permanent, just modify /etc/X11/xorg.conf.d/10-synaptics.conf.

Note: Right/Middle ButtonArea options are only recognized once the X fully loads the driver. To work around this, create a script file /usr/local/bin/synarea.sh, write the required synclient commands, and add the script to the X startup sequence.

Using Touchegg

toucheggAUR is an application that can recognize additional gestures. To use this you'll need to replace the synaptics driver with xf86-input-synaptics-mtpatchAUR.

$(HOME)/.config/touchegg/touchegg.conf
...
<application name="All">
        ...
        <gesture type="DRAG" fingers="3" direction="ALL">
                <action type="DRAG_AND_DROP"></action>
        </gesture>
        ...
</application>
