A few people suggest I try current. I tried it and the ports show up again, this time as XHCI. They are unreliable, as others have noted: http://marc.info/?l=openbsd-misc&m=141614729913281&w=2
I use this laptop as my main workstation, so I'm going to retreat back to 5.5-stable for now, but I'll see if I can get a kernel built with the XHCI debugging on so I can help gather info on the XHCI issues. Excerpts from Scott Bonds's message of 2014-11-15 01:35:32 -0800: > I've been running 5.5 on my MacbookAir5,1 for some time.
