User:Elinux/MacBook Pro 12,1
On MacBook Pro models from 2015 (i.e. 12,x) most of the installation methods are the same as 11,1, with a few variations.
Preparing for the Installation
Preparing the hard drive
Dual booting with OS X may be desirable if you wish to update firmware. If this is the case, in order to carry out the installation you will need to shrink the main OS X HFS+ partition from within OS X's Disk Utility program, this will also move the OS X Recovery partition to the end of the OS X partition.
Installation
Booting the live image
To begin your installation, download the current ISO and write it to your USB drive according to the USB flash installation media instructions. Boot from the created USB drive by selecting it in the Apple boot manager which is accessible by holding Alt
on power on.
rEFIt and REFInd depending on how they are configured can also allow you to boot from the media.
If the install media you are using has a kernel version earlier than 3.13 you will need to edit the boot entry in the syslinux boot loader. This can be accomplished by pressing Tab
to edit the entry and append nomodeset
this will prevent visible screen corruption.
If the install media you are using has a kernel version later than 3.13 do not use nomodeset
as it is not needed and will break VA-API.
Console
As this model of notebook has a high DPI display, the console font displayed will be extremely small and depending on your preferences is likely to be uncomfortable to use. You may wish to change this for a more legible font, an example of which is;
$ setfont sun12x22
Internet
Wired
Thunderbolt Ethernet adapters and USB-to-Ethernet adapters should be picked up automatically.
Wireless
As mentioned below, broadcom-wl
is sufficient if you are using the Linux mainline kernel. For custom kernels, you need to use broadcom-wl-dkms
. Both are available from the AUR. The easiest way to get Wi-Fi connectivity during install is to build the package driver on a separate system. Note that it does have to be built against the exact same kernel version as used by the installer, and this may differ from the latest version. If built against the wrong kernel you may encounter an error (ERROR: could not insert 'wl': Invalid argument) upon modprobe. Build the package as follows:
$ curl -O https://aur.archlinux.org/cgit/aur.git/snapshot/broadcom-wl-dkms.tar.gz $ tar -zxvf broadcom-wl-dkms.tar.gz $ cd broadcom-wl-dkms $ makepkg -s
This will give you a package (broadcom-wl-*.pkg.tar.xz
) which can be installed using pacman. Put this package on a USB drive, mount it, and install the package using:
# pacman -U broadcom-wl-*.pkg.tar.xz # modprobe wl # modprobe brcmfmac
You may now use wifi-menu
to connect to your network of choice.
these allow you to build the broadcom driver again and connect (provided you put the AUR tarball for the driver on USB drive too):
dkms,wpa_supplicant, dhcpcd (dialog and netctl are needed if you want to usewifi-menu
again after you boot)Bootloader
Using the MacBook's native EFI bootloader (recommended)
Method 1: creating an extra apple-format bootable partition with GRUB
This method uses the MacBook's native EFI bootloader, i.e. the one the can be reached when holding the alt-key during boot. For additional info, see GRUB EFI Examples#Apple Mac EFI systems.
At the end of the Arch Linux install process we would normally install GRUB (or a variation) to a partition on the drive. For this method we will place a boot.efi
file on an extra partition used by the MacBook's native bootloader.
First, install the grub package from the official repositories. Make sure to follow the steps for setting up grub on a partition using the grub-install
and grub-mkconfig
commands, like normal. We will use the config file that grub-mkconfig
creates to generate a standalone boot.efi
file using the grub-mkstandalone
command, then we will wipe your just-created grub partition and set it up for Mac's native bootloader (or you can simply create a new partition and leave the grub partition alone, it is up to you).
When generating a grub config file, GRUB looks to /etc/default/grub
for its configuration. Edit the parameter GRUB_CMDLINE_LINUX_DEFAULT
to look something like this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet rootflags=data=writeback libata.force=noncq"
The libata.force=noncq
parameter will prevent SSD lockups and the rootflags
option is used for SSD-performance.
rootflags
option on Btrfs. It is not supported.Now we generate the boot.efi
file (in our current working directory):
# grub-mkconfig -o /boot/grub/grub.cfg # grub-mkstandalone -o boot.efi -d /usr/lib/grub/x86_64-efi -O x86_64-efi /boot/grub/grub.cfg
Put this file on a USB (or other OS X accessible media) and reboot into OS X.
Launch DiskUtility.app
and reformat the extra partition (or just make a new one) as HFS+ (in the "Erase" tab of Disk Utility), mount it, then create the following directory structure and file:
$ mount -t hfs /dev/diskXsY <Path to root of extra partition> $ mkdir -p <Path to root of extra partition>/System/Library/CoreServices $ touch <Path to root of extra partition>/mach_kernel
where diskXsy
is the disk your partition is on (e.g. disk0s1). You can use diskutil list
to list your disks and partitions.
Copy the boot.efi
file to the <Path to extra partition>/System/Library/CoreServices/
directory. Using your editor of choice, create a SystemVersion.plist
file in the CoreServices directory, which is located here:
<path to extra partition>/System/Library/CoreServices/SystemVersion.plist
Edit that file to look like this:
<?xml version="1.0" encoding="utf-8"?> <plist version="1.0"> <dict> <key>ProductBuildVersion</key> <string></string> <key>ProductName</key> <string>Linux</string> <key>ProductVersion</key> <string>Arch Linux</string> </dict> </plist>
The last step is then to bless (make bootable) the extra partition (as root):
# bless --folder=<Path to root of extra partition> --file=<Path to root of extra partition>/System/Library/CoreServices/boot.efi --setBoot # bless --mount=<Path to root of extra partition> --file=<Path to root of extra partition>/System/Library/CoreServices/boot.efi --setBoot
grub.cfg
and boot.efi
will have to be generated. This can be done from in Linux, without booting OS X.Generate grub.cfg
and boot.efi
from Arch Linux:
# grub-mkconfig -o /boot/grub/grub.cfg # mount -t hfsplus -o force,rw /dev/sdXY /mnt # mount the HFS+ partition # grub-mkstandalone -o /mnt/System/Library/CoreServices/boot.efi -d /usr/lib/grub/x86_64-efi -O x86_64-efi /boot/grub/grub.cfg
Method 2: Using the default EFI System Partition with Grub
Direct EFI booting (rEFInd)
See: UEFI_Bootloaders
As of August 2013, refind can automatically detect the Arch kernel, removing the need for copying the kernel into the EFI partition. Simply install refind without the EFI file system drivers [1] using the --nodrivers
option [2], and enable the scan_all_linux_kernels
and also_scan_dirs
options in refind.conf
(see link above for instructions.).
An alternative way is to omit all the scans and put the following bootentry at the end of your "refind.conf":
menuentry "Arch" { icon EFI/refind/icons/os_arch.icns volume <Volume label> ostype Linux loader /boot/vmlinuz-linux initrd /boot/initramfs-linux.img options "rw root=/dev/<arch partition> rootfstype=<filesystem type> libata.force=noncq" }
Do not forget to replace the angle brackets with your data.
Direct EFI booting (systemd-boot)
See systemd-boot.
GRUB (with OS X)
Another solution is to install GRUB. Edit /tmp/install/boot/grub/grub.cfg
and edit the boot entry to load Linux mainline instead of the normal one.
libata.force=noncq
helps with hangs due to SSD speed.Now cd into /tmp/install/
and create the GRUB image by running:
grub-mkstandalone -o bootx64.efi -d usr/lib/grub/x86_64-efi -O x86_64-efi -C xz boot/grub/grub.cfg
This will create file called boot64.efi
which contains GRUB and the configuration file incorporated inside. It is important to cd
into the right directory to make it pick up the configuration file and put it into the right place within the image.
Copy this file to the MacBook's EFI partition. The downside of this method is that you need to repeat this step whenever you want to change the GRUB config. Reboot the machine and you should be able to select your installed Arch Linux by keeping the Alt
button pressed. It should appear as EFI boot
.
To generate a nicer config use: grub-mkconfig
, remove quiet
if you like the text, then to update your GRUB post-installation, do this to make the GRUB EFI file and put it in the EFI partition:
cd / grub-mkstandalone -o bootx64.efi -d usr/lib/grub/x86_64-efi -O x86_64-efi -C xz boot/grub/grub.cfg sudo mount /dev/sda1 /mnt sudo cp bootx64.efi /mnt/EFI/boot/bootx64.efi

Console
Largest console font (although ugly) achieved by adding FONT=sun12x22
to /etc/vconsole.conf
It is still tiny but is at least readable.
Graphics
MacBook Pro 11,1
- Intel works on 3.12 with nomodeset
- Intel works from 3.13.4-1-ARCH
MacBook Pro 11,2
- Intel works from 3.13.4-1-ARCH
MacBook Pro 11,3
- Nvidia works (both 319.60 and 331.17 drivers)
- Intel works after patching grub, see below
MacBook Pro 11,5
- The xf86-video-nouveau package seems to be stable. Switching to VTs and back works fine from MATE and GNOME. SOmetimes Chromium causes a "kernele rejected pixbuf" error which freezes the desktop.
- The nvidia-dkmsAUR driver has been crashing a lot.
- The nvidia driver seems to be super stable, but GNOME desktop won't like to start, showing you a "Oh no! Something has gone wrong" message. Cinnamon Desktop is buttery smooth with the nvidia driver, and if you want your GNOME desktop, you can run `gnome-shell --relace &` while in cinnamon desktop to switch to Gnome Shell as a workaround.
Microcode
You may need to install intel-ucode, especially if you have Nvidia drivers. Read the wiki page to learn more about Microcode.
HiDPI
Gnome works out of box. See HiDPI for information on how to tweak the system for a Retina screen.
Xfce
If you are using Xfce, you will probably experience tearing in Firefox, VLC, etc. Until newer versions of xfwm support OpenGL rendering, use another compositing window manager like compton with backend = "glx"
.
lightdm
Lightdm has some compatibility issues. If you are using lightdm on HiDPI/Retina screens you may experience a small login box , to use the native resolution of 2560x1600 on the login screen create a script
#!/bin/sh xrandr --output eDP1 --primary --mode 2560x1600
and set it as display-setup-script in /etc/lightdm/lightdm.conf
MATE
MATE's Marco seems to have problems. Replace it with GNOME's Mutter for nice animated effects. This works best with the nouveau driver.
# mutter --replace &&
Or configure MATE to use Mutter in dconf...
GNOME
It all works great out of the box with the nouveau driver.
Getting the integrated intel card to work on 11,3
By default the integrated card is powered off. To fix this we need a grub function called "apple_set_os". This function has not officially been merged yet, so we need to build grub ourselves. Download the grub-gitAUR package from the AUR. Using something like:
$ packer -G grub-git $ cd grub-git
Get the patch from here: http://lists.gnu.org/archive/html/grub-devel/2013-12/msg00442.html
Put the patch contents into a file labeled something like "apple.patch"
Add this patch to your PKGBUILD and run:
$ makepkg -si
Reboot into OS X and download gfxCardStatus v2.2.1 (newer versions do not work properly) run the app and specify the integrated card.
Reboot and at the grub prompt type 'c' to get into console, followed by "apple_set_os" at the prompt.
You should now be able to install xf86-video-intel and get your card running.
Note that the HDMI port and MiniDP are soldered to the nvidia card meaning that to run external displays you need to use the dedicated card.
Alternative method to disable NVIDIA card
While the above method for switching graphics works, there is a more effective method that does not require the use of gfxCardStatus or a patched GRUB installation (but it can be used if desired).
First, the Intel GPU will not function without a patch called apple_set_os. You can either use a patched GRUB (as seen above) or use the apple_set_os.efi patch via rEFInd or chainload it via GRUB, the EFI patch can be download here, https://github.com/0xbb/apple_set_os.efi, this tricks the machine into thinking that it is booting a Mac OS X installation, making the hardware behave as such, allowing the Intel GPU to be used. rEFInd should automatically detect the patch as described on the application page. This will need to be loaded before each boot of Arch or else the Intel GPU will not function, to load it automatically it can be chainloaded via GRUB. Also, download and install the Intel drivers as described above.
Then you will need to download an application called gpu-switch for switching the GPU on dual MacBook Pros, it is fairly easy to use as well. It can be downloaded from here, https://github.com/0xbb/gpu-switch.
Secondly, once you have downloaded gpu-switch, extract the application to your home directory and open up a terminal emulator and cd to that directory. To switch to the Intel graphics, run gpu-switch -i
as sudo, and the card will be active on reboot. Conversely, to enable the dedicated card instead, run gpu-switch -d
as sudo. You must have booted with the aforementioned patch for this to work.
Next, gpu-switch will not completely power down the dedicated card. To do that, you will have to create a custom grub menuentry and compile a program that will power off the dedicated card.
To do that, please refer to the following article, MacBookPro10,x#Graphics_2.
You should now have working integrated graphics and the dedicated GPU should now power down. If you get a blank screen after doing this, wait and see what happens, if it stays blank for a prolonged period of time, try resetting the SMC, and then booting back into Arch.
I noticed that afterwards VGA switcheroo disabled the nouveau driver, if this workaround still does not work, try installing a cronjob package, and adding the following:
@reboot echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
@reboot echo IGD > /sys/kernel/debug/vgaswitcheroo/switch
I'm not sure if the vgaswitcheroo commands actually do anything, I need somebody to test this workaround and let me know how it works for them.
To see if you dedicated GPU is actually disabled, run:
sudo cat /sys/kernel/debug/vgaswitcheroo/switch
NOTICE: gpu-switch has been tested only on a select few models, those being MacBookPro9,1, MacBookPro10,1, and MacBookPro11,3. Use at your own risk.
Sound
- Headphones work
- Speakers work from kernel 3.13 and 3.12.2. 3.12.1 only with patch
- Patch: https://bugzilla.kernel.org/attachment.cgi?id=114081.
- See discussion here: https://bugzilla.kernel.org/show_bug.cgi?id=64401
- Optical audio can be turned off and on with above sound patch.
If you do not want to hear the annoying sound at system start-up, one way to get rid of it is to turn sound off while under Mac OS.
Volume keys can be made to work with xfce4-volumed
(if you are using Xfce).
Also, if you are using PulseAudio, sometimes it thinks HDMI is the default sound card; to solve this problem, install pavucontrol and set Analog Stereo as the fallback device.
Touchpad
One method is to install xf86-input-synaptics and configure to your liking in /etc/X11/xorg.conf.d/50-synaptics.conf
:
Section "InputClass" MatchIsTouchpad "on" Identifier "touchpad catchall" Driver "synaptics" # 1 = left, 2 = right, 3 = middle Option "TapButton1" "1" Option "TapButton2" "3" Option "TapButton3" "2" # Palm detection Option "PalmDetect" "1" # Horizontal scrolling Option "HorizTwoFingerScroll" "1" # Natural Scrolling (and speed) Option "VertScrollDelta" "-100" Option "HorizScrollDelta" "-100" EndSection
Ctrl-Click as Right-Click
Using this SuperUser receipt [3] I got Ctrl-click working as right-click. I had to increase the sleep time to 0.1 though.
input-mtrack
Another method is to use xf86-input-mtrack-git [4]. If you like to have a thumb resting on the touchpad, this driver is the right choice, because it has an option for IgnoreThumb.
With this config the touchpad behavior becomes more osx-like.
/etc/X11/xorg.conf.d/00-touchpad.conf
Section "InputClass" MatchIsTouchpad "on" Identifier "Touchpads" Driver "mtrack" Option "Sensitivity" "0.64" Option "FingerHigh" "5" Option "FingerLow" "1" Option "IgnoreThumb" "true" Option "IgnorePalm" "true" Option "DisableOnPalm" "true" Option "TapButton1" "1" Option "TapButton2" "3" Option "TapButton3" "2" Option "TapButton4" "0" Option "ClickFinger1" "1" Option "ClickFinger2" "2" Option "ClickFinger3" "3" Option "ButtonMoveEmulate" "false" Option "ButtonIntegrated" "true" Option "ClickTime" "25" Option "BottomEdge" "30" Option "SwipeLeftButton" "8" Option "SwipeRightButton" "9" Option "SwipeUpButton" "0" Option "SwipeDownButton" "0" Option "ScrollDistance" "75" Option "VertScrollDelta" "-111" Option "HorizScrollDelta" "-111" EndSection
Keyboard backlight
- Works, see MacBook#Keyboard_Backlight
- On KDE controlling the backlight with the increase or decrease brightness keys work fine, but they need upower to start before the desktop. To do this create the file
/etc/systemd/system/kdm.service.d/kbd_backlight.conf
with this content (you might need to create the directory as well)
[Unit] Requires=upower.service After=upower.service
Screen backlight
- Intel, works on Linux 3.13
- Framebuffer, works for MacBook Pro 11,1 and 11,3 via
/sys/class/backlight/gmux_backlight/brightness
. - Brightness in
/sys/class/backlight/gmux_backlight/brightness
can be modified comfortably via the gmux_backlightAUR utility without root privileges. Requires thesetpci
setting below. - Nvidia, does not work using default settings. Try adding
setpci -v -H1 -s 00:01.00 BRIDGE_CONTROL=0
to/etc/rc.local
.
i915.invert_brightness=1
to the kernel. Suspend
- Works from Linux 3.13
- It may be necessary to disable USB's wakeup ability by by echoing 'XHC1' to '/proc/acpi/wakeup' in order to prevent immediate wakeup on suspend.
- No backlight after suspend with Linux 3.12
- Use hibernate instead
Powersave
Disabling the internal cardreader and bluetooth controller may save battery life. When not using them, create the following udev rules:
/etc/udev/rules.d/99-apple_cardreader.rules
SUBSYSTEMS=="usb", ATTRS{idVendor}=="05ac", ATTRS{idProduct}=="8406", RUN+="/usr/local/sbin/remove_ignore_usb-device.sh 05ac 8406"
/etc/udev/rules.d/99-apple_broadcom_bcm2046_bluetooth.rules
SUBSYSTEMS=="usb", ATTRS{idVendor}=="05ac", ATTRS{idProduct}=="8289", RUN+="/usr/local/sbin/remove_ignore_usb-device.sh 05ac 8289" SUBSYSTEMS=="usb", ATTRS{idVendor}=="0a5c", ATTRS{idProduct}=="4500", RUN+="/usr/local/sbin/remove_ignore_usb-device.sh 0a5c 4500"
As udev's OPTIONS=="ignore_device"
may not work reliably, the above rules use a script to manually remove the usb device from /sys/bus/usb/devices/
.
If battery life is not satisfactory, it may help to use power saving utilities, such as tlp, and/or powertop from the official repositories. To better optimize battery life, TLP also has a configuration file located at /etc/default/tlp
that you can edit to suit your machine. For more information, visit the wiki pages for these tools, TLP and Powertop, respectively.
SD Card Reader
- Disappears sporadically after suspend as of Linux 3.18. Workaround is to create
/etc/modprobe.d/xhci-reset-on-suspend.conf
with:
# Reset XHCI USB devices on suspend/resume, fixes SD Card reader vanishing after suspend options xhci_hcd quirks=0x80
Note: As of Linux 3.18.6-1 (and possibly earlier versions post-3.18), this fix may not be needed and might cause issues ranging from failed suspend to the SD card not being recognized at all. Test with and without the fix to determine which works best for you.
Repurpose the power key
By default systemd handles the rMBPs power key as defined in /etc/systemd/logind.conf. By setting
HandlePowerKey=ignore
systemd ignores power key events.
Now the power key can be repurposed as keycode 124. For example in i3 conf:
bindcode 124 ...
