ax0n, Is that a model with both integrated Intel gpu and dedicated Radeon gpu? Maybe look at drm(4) and try removing the radeon driver since the intel one should work fine.
The intel drivers work great on my early-2015 MBP (i5 Broadwell), but then again it doesn't have any dedicated graphics. -Dave On Thu, Sep 21, 2017 at 6:19 PM, Ax0n <a...@h-i-r.net> wrote: > I have a Mid-2015 MacBook Pro that I'm trying to get OpenBSD on.
