Which devices work ?

So…you want to install Gentoo Linux on MacBook Pro 2015 ? Here’s what I got:

Wifi

The official broadcom-sta-6.30.223.248-r3 driver doesnt seem to like BCM43602 which is used in MBPR 12,1, so we should use a kernel provided driver brcfmac.

Use the brcmfmac driver shipped with the linux kernel to enable wifi, you also need to install sys-kernel/linux-firmware for /lib/firmware/brcm/brcmfmac43602-pcie.bin.

I use /etc/portage/savedconfig/sys-kernel/linux-firmware to control which firmware I need to install, and the firmware we need to make wifi work is

brcm/brcmfmac43602-pcie.bin

Add the savedconfig file, and enable savedconfig USE to emerge linux-firmware

USE="savedconfig" emerge sys-kernel/linux-firmware

TouchPad

Works great! two finger scrolling and left/right button can work.

Suspend

Appears to work, I use the suspend to RAM method

SD Card Reader

SD card reader has been not worked for a long time, after I upgraded to macOS Sierra version 10.12.6 , it works now :P.

You should have the following lsusb info:

Bus 002 Device 002: ID 05ac:8406 Apple, Inc.
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 05ac:0273 Apple, Inc. Internal Keyboard/Trackpad (ISO)
Bus 001 Device 002: ID 05ac:8290 Apple, Inc. Bluetooth Host Controller
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

The device 05ac:8406 is the sdcard reader, make sure it exists or not.

QA

Users with id (501) not shown in GDM ?

NOTE: I think I am wrong, cant’ make this work yet.

To make compatible with my Mac, I changed the Linux user to uid:gid 501:20, and found there’s no user listed in GDM, this may be due to /etc/login.defs having values like

UID_MIN                  1000

change it to following, and the user will show up (maybe ?)

UID_MIN                   500

How to add “Mac OSX” to grub menu

Just add the following entry to /etc/grub.d/40_custom

menuentry "Mac OSX" {
    insmod hfsplus
    search --set=root --file /System/Library/CoreServices/boot.efi
    chainloader /System/Library/CoreServices/boot.efi
}

Then use these commands to rebuild grub menu.

grub-mkconfig -o /boot/grub/grub.cfg
