Hi, I'm using the snapshot install77.img to install because apparently the 7.6 had a bug which stopped the bwfm0 from showing up entirely on newer system firmware and there's an errata for this at https://ftp.openbsd.org/pub/OpenBSD/patches/7.6/common/004_aplsmc.patch.sig The MacOS I have is at 15.4.
When I boot into the installer it already complains about the firmware being missing for bwfm0. I mounted the EFI system partition with firmware.tar, extracted the brcmfmac4378b1-pcie.apple,shikoku.bin, put it in /etc/firmware/apple-bwfm. >From what I understand, this should be happening automatically. When I bring up the bwfm0 I get some output in dmesg about a crash and after a while the system reboots. I think the brcmfmac4378b1-pcie.apple,shikoku.bin should be the correct one for the M1 Air according to https://lore.kernel.org/all/20220104072658.69756-10-mar...@marcan.st Here's the dmesg output, with the crash starting with "RTKit crashed:" OpenBSD 7.7 (RAMDISK) #347: Wed Apr 9 14:37:26 MDT 2025 dera...@arm64.openbsd.org:/usr/src/sys/arch/arm64/compile/RAMDISK real mem = 8005144576 (7634MB)
