1. Create a file called chromebook-usbc.service file in /etc/systemd/system/

2. Paste the following contents into the file:

   [Unit]
   Description=Enable USB-C on chromebook
   
   [Service]
   Type=oneshot
   RemainAfterExit=yes
   ExecStartPre=/sbin/modprobe -r -a cros-ec-typec intel-pmc-mux
   ExecStart=/sbin/modprobe -a intel-pmc-mux cros-ec-typec

CELES Post Install Workaround

If you experience issues in applications such as Parsec, or encounter disruptive freezes, adding the kernel parameters clocksource=hpet hpet=force may fix your problem. The following instructions assume you're using GRUB, and will be different for other bootloaders. Do your own research on how to set kernel parameters in your bootloader if these do not apply.

1. Edit /etc/default/grub with your preferred text editor (e.g. nano).
2. Add clocksource=hpet hpet=force inside of GRUB_CMDLINE_LINUX_DEFAULT and save your changes. If you exclude either parameter, this will not work. Use sudo, su, or doas if necessary.
3. Type grub-mkconfig -o /boot/grub/grub.cfg or update-grub into a terminal and press Enter. Use sudo, su, or doas if necessary.
4. Reboot

macOS

• Remove Verbose
• OpenCore GUI Setup
• Disable DevirtualiseMmio if you're on CometLake (10th gen)
