What's the situation with Broadcom wifi on your intel macs?
We've run into instability issues with the newer Linux kernels (starting with 6.x, I think) and have had to stop upgrading.
Ah, we have all connected via Ethernet. Side-stepped the WiFi issue. ;-) But have read of others successfully navigating it.
I've just setup a new ThinkPad with openbsd. You just need to put the firmware needed on a usb stick, mount it and run one command, fw_update -p ./ It wasn't hard.
