The EndeavourOS ARM team is quite small. Currently it is just myself and I don’t know anything about Apple silicon.
So if someone wants to create an image for Mac M3, they would be the lead developer for that project. I would help as much as I can. Perhaps other users interested in this could join in and form a MAC M3 team.
Here is the best Topic we have on M1 & M2. I don’t know if this applies to M3 or not.
