At this point it seems M1 Macs have better Linux/other unixes support than Intel Macs with a T2 chip. At least from my experience and what I’m seeing with Asahi Linux.
The forthcoming GPU and sound support are all I'm waiting for to move my daily OpenBSD workstation to my M1 mini. I tested Asahi Linux on it earlier this morning and it was mind-bogglingly fast. My fastest AMD64 based system is a Ryzen 5 3600 with a NVMe main storage drive, and Linux on the M1 makes it feel like a 10 year old i3 with a spinning drive in comparison. Everything is just instant, file transfers are faster than they are on macOS on the same machine, and even without GPU acceleration, KDE Plasma is quick and fluid. I ran out of time to try OpenBSD today but I'll jump on that this week and see if the performance carries over to it.
Hope to see a write up on it somewhere! I bought my M1 air specifically to run a powerful arm computer with Linux/BSD once it is decent enough! I am in my last semester and don't want to tamper with my machine until that is over, so once I graduate in a month, I have plans to look into doing this. If OpenBSD is in a usable state, that'll be what gets loaded on sometime in may.
Definitely! I don't have much of an online presence beyond here, OSNews, Ars Technica, and Reddit, but I have been wanting to start a blog about my tech hobbies (OpenBSD primarily) and this would be a good start for it. I'll be sure to add it to my profile here once I've started it.
