I am considering getting a MacBook Air M1 to play around with Asahi Linux (or some Linux on M1 project) and I would like to try to run KaOS on my new MacBook. How do I get it to run? Will it work or will there be support for MacBooks in the future.

KaOS has generally run well on Macbooks, but only way to find out if such a model is supported is by testing in Live mode. If your hardware is not supported there, no use to install.

EDIT:
As noted below, no need to even try, ARM is not supported in KaOS.

Small clarification, M1 is ARM architecture, KaOS is compiled for x86-x64
