T2-Ubuntu

The ISOs from this repo should allow you to install Ubuntu without using an external keyboard or mouse on a T2 Mac. It works in my MacBook Pro 16 inch, 2019.

If this repo helped you in any way, consider inviting a coffee to the people in the credits, link.

UBUNTU ISO with Apple T2 patches built-in.

Apple T2 drivers are integrated with this iso.

This repo is a rework of the great work done by @mikeeq and @marcosfad

I'm using the Kernel from - https://github.com/t2linux/T2-Ubuntu-Kernel

Using additional drivers:

• Apple T2 (apple-bce) (audio, keyboard, touchpad)
• Touchbar (apple-ibridge, apple-ib-tb, apple-ib-als)

Bootloader is configure correctly out of the box. No workaround needed.

Installation

1. Reduce the size of the mac partition in MacOS
2. Download ISO file from releases.
3. Copy it to a USB using dd (or gdd if installed over brew):

diskutil list # found which number has the USB
diskutil umountDisk /dev/diskX
sudo gdd bs=4M if=ubuntu-20.04-5.6.10-mbp.iso of=/dev/diskX conv=fdatasync status=progress

4. Boot in Recovery mode and allow booting unknown OS
5. Restart and immediately press the option key until the Logo come up
6. Select "EFI Boot" (the third option was the one that worked for me)
7. Launch Ubuntu Live
8. Use Ubiquity to install (just click on it)
9. Select the options that work for you and use for the partition the following setup:
   • Leave the efi boot as preselected by the installer, unless you require a separate efi partition.
   • Add a ext4 partition and monted as /.
   • Swap and other partitions are optional.
10. Run the installer.
11. Shutdown and remove the USB Drive.
12. Start again using the option key. Select the new efi boot.
13. Enjoy.

Configuration

• See https://wiki.t2linux.org/guides/wifi/
• To install additional languages, install appropriate langpack via apt sudo apt-get install language-pack-[cod] language-pack-gnome-[cod] language-pack-[cod]-base language-pack-gnome-[cod]-base
  • see https://askubuntu.com/questions/149876/how-can-i-install-one-language-by-command-line
• You can change mappings of ctrl, fn, option keys (PC keyboard mappings) by creating /etc/modprobe.d/hid_apple.conf file and recreating grub config. All available modifications could be found here: https://github.com/free5lot/hid-apple-patched

# /etc/modprobe.d/hid_apple.conf
options hid_apple swap_fn_leftctrl=1
options hid_apple swap_opt_cmd=1

MISC

GRUB_TIMEOUT_STYLE=menu
GRUB_TIMEOUT=10

and then: sudo update-grub

Update to newer kernels

Follow this guide.

Know issues

• Checksum is failing for 2 files: md5sum.txt and /boot/grub/bios.img

Not working (Following the mikeeq/mbp-fedora)

• Dynamic audio input/output change (on connecting/disconnecting headphones jack)
• TouchID
• Thunderbolt (is disabled, because driver was causing kernel panics (not tested with 5.5 kernel))
• Microphone (it's recognised with new apple t2 sound driver, but there is a low mic volume amp)

Known issues

• ctrl+x is not working in GRUB, so if you are trying to change kernel parameters - start your OS by pressing F10 on external keyboard
