Noa Himesaka from t2linux created an EndeavourOS ISO in collaboration with @joekamprad, especially for Intel Macs and iMac Pros from 2018 and up, shipped with the T2 security chip.
According to the team, the Cassini T2 release features a revamped installer, Dracut instead of mkinitcpio and lots more.
