Yes the language was a bit colourful but the point remains.
M1/M2 and A18 Pro are not the same and Asahi, which is available for M1 and M2 cannot just run on an A18 Pro: https://github.com/rusch95/asahi_neo
I thought you'd also need adaptations of your drivers for an A18 Pro compared to an M4 but maybe I was mistaken there. Certainly M1 and M2 compatibility does not suffice.
