mbp-fedora | Fedora ISO with Apple T2 patches

Turn off secure boot and allow booting from external media - https://support.apple.com/en-us/HT208330. Download .iso from releases section - https://github.com/mikeeq/mbp-fedora/releases/latest. Next you can check the SHA256 checksum of extracted .ISO to verify if your extraction process went well.

Download .iso from releases section - https://github.com/mikeeq/mbp-fedora/releases/latest If it's split into multiple zip parts, i.e.: livecd.zip and livecd.z01 you need to download all zip parts and then join split files into one and then extract it via unzip https://unix.stackexchange.com/questions/40480/how-to-unzip-a-multipart-spanned-zip-on-linux or extract downloaded zip parts directly using: on Windows winrar or other supported tool like 7zip on Linux you can use p7zip, dnf install p7zip and then to extract 7za x livecd.zip on MacOS you can use the unarchiver from AppStore: https://apps.apple.com/us/app/the-unarchiver/id425424353?mt=12 or you can install p7zip via brew brew install p7zip and use 7za x livecd.zip command mentioned above to install brew follow this tutorial: https://brew.sh/
Next you can check the SHA256 checksum of extracted .ISO to verify if your extraction process went well MacOS: shasum -a 256 livecd-fedora-mbp.iso Linux sha256sum livecd-fedora-mbp.iso please compare it with a value in sha256 file available in github releases
Burn the image on USB stick >=8GB via: Fedora Media Writer Download: https://getfedora.org/en/workstation/download/ MacOS https://getfedora.org/fmw/FedoraMediaWriter-osx-latest.dmg if you're prompted that application is insecure/from unknown developer, check https://support.apple.com/en-us/HT202491 Windows https://getfedora.org/fmw/FedoraMediaWriter-win32-latest.exe Please use Custom Image option when burning the downloaded and extracted ISO to USB drive dd Linux sudo dd bs=4M if=/home/user/Downloads/livecd-fedora-mbp-201908181858.iso of=/dev/sdc conv=fdatasync status=progress MacOS try to find under which /dev/ your USB stick is available sudo diskutil list check if any partitions from it are mounted df -h, if they are please unmount sudo diskutil unmount /dev/disk2s1 exec sudo dd if=/Users/user/Downloads/livecd-fedora-mbp-201908181858.iso of=/dev/disk2 bs=4m if dd is not working for you for some reason you can try to install gdd via brew and use GNU dd command instead sudo gdd bs=4M if=/Users/user/Downloads/livecd-fedora-mbp-201908181858.iso of=/dev/disk2 conv=fdatasync status=progress # To install gdd via brew, execute brew install coreutils don't worry if dd command execution is slow on MacOS, it can take a while due to XNU's poor I/O performance Rufus (GPT)- https://rufus.ie/, if prompted use DD mode Please don't use livecd-iso-to-disk as it's overwriting ISO default grub settings and Fedora will not boot correctly!
Install Fedora First of all I recommend to shrink (resize) macOS APFS partition and not removing macOS installation entirely from your MacBook, because it's the only way to keep your device up-to-date. macOS OS updates also contains security patches to EFI/Apple T2 HowTo: https://www.anyrecover.com/hard-drive-recovery-data/resize-partition-mac/ # Steps to Resize Mac Partition Boot Fedora Installer from USB drive directly from macOS boot manager. (You can boot into it by pressing and holding Option key (ALT key) after clicking the power-on button when your computer was turned off or on restart/reboot when Apple logo is shown on the screen). There will be two/three boot options available, usually the last one works for me. (There are multiple boot options, because there are three different partitions in the ISO to make the ISO bootable on different set of computers: 1) ISO9660: with installer data, 2) fat32, 3) hfs+) I recommend using standard partition layout during partitioning your Disk in anaconda (Fedora Installer) as I haven't tested other scenarios yet. https://github.com/mikeeq/mbp-fedora/issues/2 /boot/efi - 1024MB Linux HFS+ ESP /boot - 1024MB EXT4 / - xxxGB EXT4 There will be an error on Installing bootloader... step, click Yes - It's related to efi=noruntime kernel arg # /tmp/anaconda.log 13:39:49,173 INF bootloader.grub2: bootloader.py: used boot args: resume=UUID=8a64abbd-b1a3-4d4a-85c3-b73800e46a1e rd.lvm.lv=fedora_localhost-live/root rd.lvm.lv=fedora_localhost-live/swap rhgb quiet 13:39:54,649 ERR bootloader.installation: bootloader.write failed: Failed to set new efi boot target.

To install additional languages, install appropriate langpack via dnf dnf search langpack
After login you can update kernel by running sudo update_kernel_mbp, more info here: https://github.com/mikeeq/mbp-fedora-kernel#how-to-update-kernel-mbp
You can change mappings of ctrl, 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 sudo -i # Refresh grub and dracut config by executing update_kernel_mbp script update_kernel_mbp
To change function key mappings for models with touchbar see modinfo apple_ib_tb and use echo 2 > /sys/class/input/*/device/fnmode instead of the hid_apple options. See this issue
