NOTE: This is for dual-booting OS X 10.11 with Ubuntu 16.04.
Resize OS X partition with Disk Utility.
In Recovery Mode (hold command-R on startup), disable SIP so as to be able to install rEFInd (updated fork of rEFIt).
csrutil disableDownload the Ubuntu 16.04 64-bit ISO from ubuntu.
I prefer using dd to create a LiveUSB.
Shut down. Hold the Option (Alt) key, and then press the power button to select the LiveUSB.
My memory of this step is a bit..fuzzy. Use at your own discretion.
Use gparted to create an ext2 partition of 512MB after the third partition, which is the OS X Recovery HD, and an ext4 partition with the remaining free space.

# Launch the installer with -b flag to skip bootloader installation
ubiquity -bChoose "Something else", and then mount the newly created ext2 as /boot, and /dev/mapper/vgcrypt as /. Keep FORMAT unchecked.
Choose to 'Continue testing', DO NOT reboot yet.
You then need to do some stuff with chroot.
# may need to remount
sudo -i
blkid | grep ^/dev/sda5 # copy the UUID value
for i in /dev /dev/pts /proc /sys /run; do sudo mount -B $i /mnt$i; done
chroot /mnt
# mount -t proc proc /proc
# mount -t sysfs sys /sysMy /etc/fstab looks something like this:
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

create /etc/crypttab:
NOTE I cannot remember whether this was actually necessary. I believe it may only be necessary when you need to mount an encrypted swap.

The UUID is determined from a previous step.
Back in chroot:
update-initramfs -u -k all
lsinitramfs /boot/initrd* | grep cryptsetupWhen you restart you'll boot back into OS X. Install rEFInd at this point. When you reboot, you should see the rEFInd screen.
The rEFInd entry that corresponded to Ubuntu for me was "Generic Linux /vmlinuz something something".
TODO use bootctl (formerly gummiboot) instead of rEFInd.
You don't need an internet connection to get WiFi to work. Just plug in the LiveUSB you used to install Ubuntu. Once it's mounted, you'll see a folder, /path/to/USB/pool. This is where you can get the drivers.
You'll need to copy pool/main/d/dkms-*.deb and pool/restricted/b/broadcom-*.deb to, say, ~/Desktop.
sudo dpkg -i /path/to/where/you/copied/the/debs/*.debThis should automatically load the WiFi module.

# sudo checkinstallNOTE It is not necessary to install the propriety nvidia drivers, unless you are doing some intensive graphics work that the open-source nouveau driver can't handle as well.
In Additional Drivers, enable nvidia-361. Then run
nvidia-xconfig
You'll then need to reboot.
- I would stick with text-only boot for Ubuntu (i.e. no splash screen) because it freezes at the prompt for the encrypted volume pass.
- The first time I rebooted after installing NVIDIA drivers, I had a black screen. Had to force shutdown (by pressing the power button for 8 seconds), since I could not switch to a TTY, either. But on the second boot, I was able to proceed.
My laptop ran really hot for the first few uses of Ubuntu 16.04, but cooled down over time. Really odd...It runs really hot.- Take a look at xorg.conf.
- rc.local is necessary to get brightness control to work.
This machine can run really hot when the discrete GPU, the NVIDIA card, is turned on, even if using the propriety drivers. Since I don't really do any intensive gaming or CUDA programming on this machine and need it to be portable, I keep the discrete GPU off and so use the integrated Intel card.
You do not have to install the nouveau or intel drivers manually, but for reference sake (or in case you need to reinstall them), the packages are xserver-xorg-video-intel and xserver-xorg-video-nouveau.
- systemd-vgaswitcheroo-units Set of scripts to turn off the discrete GPU at boot. NOTE This only works if you are using the open-source, Nouveau drivers rather than the NVIDIA ones.
- gpu-switch Script to switch between Intel and NVIDIA cards. However, requires that you restart your Macbook.
If you're using rEFInd as a bootloader, or bootctl (included in systemd), after installation you will need to copy the initrd and vmlinuz files to /boot/efi (where your actual EFI system partition is mounted in Ubuntu):
sudo cp {abi-4.4.8-040408-generic,config-4.4.8-040408-generic,initrd.img-4.4.8-040408-generic,vmlinuz-4.4.8-040408-generic} /boot/efi
