This is a freshly installed current/arm64 on a MAcBook Air, model 2337 (M1, 2020); full dmesg below.
After doing the Avahi Linux dance, it booted into the installer. Choosing [whole] disk in fact preserves the existing macOS paritions, which makes the disk partitioning steptoe nicely around the macOS. OTOH, the disklabel letter-names quickly run out, as many are already occupied by the partitions macOS uses. I didn't touch those to make sure I don't overwrite anything during the install - is there any point keeping them also _after_ the install? So that e.g. upgrades do not overwrite anything either? If not, I would just drop them from the disklabel to have names for more bsd partitions. When setting up ifaces, the installer complained that bwfm0: failed loadfirmware of file apple-bwfm/brcmfmac4378b1-pcie.apple,shikoku.bin so I don't have any network connection. Is that known? (I had the install sets on the USB stick.) Similarly, the booted kernel after the install cannot use bwfm, see dmesg below. Where is the firmware file supposed to be found? There is no such firmware at firmware.openbsd.org; the Avahi install created a partition (sd0m in my case) that has a firmware.tar file with all kinds of stuff, but none named *bwfm*; is that where it was supposed to be? Or is there somewhere else I can get the bwfm firmware? There is no audio at aplaudio0. X works nicely. Thank to all who make this possible!
