Asahi Linux is NOT an option and may never be one due to: The A18 Pro (and M4) introduced SPTM — Secure Page Table Monitor — which runs at a higher privilege level (GXF EL2) than the OS kernel. Unlike M1/M2/M3 where m1n1 can directly chainload Linux, on A18 Pro/M4 the page table infrastructure is owned by SPTM and must be initialized by XNU before anything else can run. You cannot bypass it. (source: https://github.com/rusch95/asahi_neo)
