I would get acquainted with vmware. OS X is then a giant hardware abstraction
layer.

you forgot skylake video, too.

The keyboard and trackpad appear to be connected over SPI:

https://bugzilla.kernel.org/show_bug.cgi?id=99891

While there may be some short path to keeping the keyboard in a
legacy mode, I'm sure the trackpad will require an entirely new
driver to be usable at all.

Some commits went into Linux to support it, but it still looks buggy
there:

https://bugzilla.kernel.org/show_bug.cgi?id=105621

So with no easy path to a working keyboard or trackpad, practically
no chance of wireless support nor even the ability to plug in a
small USB adapter due to the single USB-C port, I doubt this laptop
will be usable at all under OpenBSD.  And the keyboard sucks.

New 12" Retina Macbook (Macbook9,1)

[Bryan C. Everly]

Hello tech@

I just received my 12" Retina Macbook (the Macbook9,1) which is the
latest Skylake version.  I would really like to get OpenBSD running on
this and am happy to trace any code, build patches, stand on my head,
etc. if I could get someone interested in working with me to figure
this thing out.

Here is where things stand with the latest 6.0 snapshot:

1.  It will boot the install60.fs ramdisk image and successfully get
to the Install/Upgrade/Shell prompt

2.  The keyboard works at the boot prompt, but does not work once the
install/upgrade/shell prompt comes up

3.  My USB-C to USB 3.0 hub that I purchased works just fine to boot
USB thumb drives

4.  A USB keyboard plugged into the hub allows me to have a working
keyboard once the installer hits the prompt

5.  The internal solid state hard drive is not recognized. This is one
of the NVM Express (or some people call them NVMe) drives.  I think I
saw a patch floating around on the list to enable the controller to be
recognized.  Once I update sources I'll see if I can build a kernel
with that patch applied to see if I can get farther.

6.  The Broadcom 0x43a3 (I think it is the Broadcom 4350 chipset) WiFi
adapter is not working.  Not surprising given... well... Broadcom.

I was able to get a dmesg out of the thing by ripping out my boot USB
stick and jamming in a MSDOS formatted USB stick.  I've cut and pasted
it below.

Again, anyone willing to help me see if I can get this farther along?
