h0hmj / 0 Linux-On-MBP-Late-2016.md
This is about documenting getting Linux running on the late 2016 and mid 2017 MPB’s; the focus is mostly on the MacBookPro13,3 and MacBookPro14,3 (15inch models), but I try to make it relevant and provide information for MacBookPro13,1, MacBookPro13,2, MacBookPro14,1, and MacBookPro14,2 (13inch models) too. I’m currently using Fedora 27, but most the things should be valid for other recent distros even if the details differ. The kernel version is 4.14.x (after latest update).
The state of linux on the MBP (with particular focus on MacBookPro13,2) is also being tracked on https://github.com/Dunedan/mbp-2016-linux . And for Ubuntu users there are a couple tutorials (here and here) focused on that distro and the MacBook.
Note: For those who have followed these instructions ealier, and in particular for those who have had problems with the custom DSDT, modifying the DSDT is not necessary anymore — see the updated instructions below and make sure to update your clone of the roadrunner2/macbook12-spi-driver repo to get the latest drivers.
- Booting (i.e Grub etc)
- Recognizes disk on all models (older kernels may need patch for some models, though)
- Keyboard, touchpad, and basic touchbar functionality
- HiDPI detection
- Accelerated video
- Screen brightness control
- Keyboard backlight
- USB
- Sensors (install lm_sensors package)
- Camera
- Bluetooth (older kernels need patches)
- WiFi on MBP13,1 and MBP14,1
- WiFi on ,2 and ,3 models (though some folks have had success with some of the workarounds)
- Suspend/Resume
- Audio (two cards show up, and intel driver is loaded, but no sound)
If you want to keep your MacOS installation (generally a good idea if you can afford the disk space, because that’s the only way to get/install firmware updates), then first boot into MacOS and resize the partition there, creating a new partition for the Linux installation. If you also want to have a Windows partition, see this comment below.
Warning: If you’re not going to keep MacOS, either back up the EFI System Partition (and restore its contents to the new ESP after installation) or leave it intact (i.e. don’t do a full disk install, but just use the space after the ESP). This partition (it’s the first one) contains drivers/firmware/etc needed by Apple’s EFI loader during boot, in particular to initialize the Touchbar.
Since the internal keyboard and touchpad won’t work until you have built and loaded the drivers, you’ll need to plug in an external USB keyboard to do the initial setup and installation.
If you’re booting a 4.11 or later kernel, no special params or patches are needed.
echo 'install nvme /sbin/modprobe --ignore-install nvme $CMDLINE_OPTS; echo 106b 2003 > /sys/bus/pci/drivers/nvme/new_id' | sudo tee /etc/modprobe.d/nvme.conf echo 'force_drivers+="nvme"' | sudo tee /etc/dracut.conf.d/disk.conf sudo dracut --force --kver
sudo sed -i 's/\(GRUB_CMDLINE_LINUX=.*\)"/\1 intremap=nosid"/' /etc/default/grub sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg For this we need the drivers from https://github.com/roadrunner2/macbook12-spi-driver.git (a clone of https://github.com/cb22/macbook12-spi-driver which includes a preliminary touchbar driver and keyboard fixes). The following commands set this up.
First some extra packages:
sudo dnf install git kernel-devel dkms Next we need to prepare for the modules to be included in the ramdisk (so they are loaded early during boot):
On distros using mkinitramfs instead of dracut you’ll want to do the following instead:
Now get and build the drivers:
git clone https://github.com/roadrunner2/macbook12-spi-driver.git pushd macbook12-spi-driver git checkout touchbar-driver-hid-driver sudo ln -s `pwd` /usr/src/applespi-0.1 sudo dkms install applespi/0.1 popd Next we need to set the proper dpi for the touchpad and adjust the sensitivity (download the 61-evdev-local.hwdb and 61-libinput-local.hwdb from this gist):
sudo cp . the-downloaded-61-evdev-local.hwdb. /etc/udev/hwdb.d/61-evdev-local.hwdb sudo cp . the-downloaded-61-libinput-local.hwdb. /etc/udev/hwdb.d/61-libinput-local.hwdb sudo systemd-hwdb update You can test the drivers by loading them and their dependencies:
sudo modprobe intel_lpss_pci spi_pxa2xx_platform applespi appletb Finally, reboot to make sure it all works correctly:
Screen Brightness Control
Screen brightness control works out of the box on MacBookPro13,1 and MacBookPro13,2 (all kernels), and MacBookPro13,3 with recent kernels, but requires a kernel patch on MacBookPro13,3 with older kernels (see also Dunedan/mbp-2016-linux#2). Specifically, if you have any of these kernels you need to patch: < 4.14, 4.14 - 4.14.21, 4.15 - v4.15.5 (i.e. the issue was fixed in 4.14.21, 4.15.5, and 4.16). The following will create and install the patched apple-gmux :
mkdir apple-gmux pushd apple-gmux curl -o apple-gmux.patch 'https://bugzilla.kernel.org/attachment.cgi?id=192601' curl -o apple-gmux.c 'https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/plain/drivers/platform/x86/apple-gmux.c?id=refs/tags/v4.9.11' patch < apple-gmux.patch echo -e ' obj-m += apple-gmux.o all: \tmake -C /lib/modules/`uname -r`/build M=`pwd` modules ' >Makefile make mod=$(ls /lib/modules/`uname -r`/kernel/drivers/platform/x86/apple-gmux.ko*) sudo mv $mod sudo cp apple-gmux.ko /lib/modules/`uname -r`/kernel/drivers/platform/x86/ sudo depmod popd sudo reboot The touchpad defaults to using the bottom-left corner for right-clicks — to get 2-finger right click, install the Gnome tweak tool and change it in there.
WiFi works fine on MBP13,1 and MBP14,1. But the other models use a different chipset, and while on those the brcmfmac driver is automatically loaded, there are a number of issues with it, making it for all practical purposes unusable:
- it only does 2.4GHz — no 5GHz channels are visible
- it has an extremely low sensitivity — you must be within a few feet of the base station, and even at 5 feet distance it shows a weak signal.
- it stops working after 10 or 15 or so minutes; turning WiFi off, waiting a several minutes, and then turning it back on generally gets it working again. Maybe a thermal issue?
In the mean time some folks have that one or both of the following hacks make the WiFi work well enough them (personally, while they do improve the situation, I have not found them to be sufficient enough for actual work, i.e. I still see many packet drops and connection failures — YMMV):
- reduce the transmit power: sudo iwconfig wlp3s0 txpower 10
- edit the firmware blob ( /lib/firmware/brcm/brcmfmac43602-pcie.bin ) and modify the regrev and ccode values (see the above bugreport for details)
The amdgpu driver works well and is automatically loaded on MacBookPro13,3. On the 13 inch models the use of the intel needs to be forced (see first comment below).
MacBookPro13,3/14,3: works out of the box on kernels 4.13 and later; on earlier kernels you need the following:
echo "options uvcvideo quirks=0x100" > /etc/modprobe.d/uvcvideo.conf For MacBookPro[13,14],[12] you need the bcwc_pcie driver (mainline branch) — see also Dunedan/mbp-2016-linux#15.
As of kernel 4.16 bluetooth works out of the box; older kernels need patches — see Dunedan/mbp-2016-linux#29 (comment) and following discussion for details. But in short you’ll need to:
- Ensure your kernel is configured with CONFIG_BT_HCIUART_BCM=y
- apply the patches from hci_bcm-4.13, hci_bcm-4.14, or hci_bcm-4.15, depending on whether you have a 4.13 or earlier, 4.14, or 4.15 kernel.
- build and reboot
- on 4.14 and earlier apply the service patch from the above comment and start the service as described there (not necessary on 4.15 and later).
Note that as of 4.16 there are still issues on MacBookPro13,1 and MacBookPro14,1 — see the above bug for details on what additional patches are needed.
