 I retested my mac and I can confirm that the problem can be reproduced
 if booted without ACPI support (-2 option) on any NetBSD version.
 However, normal boot (with ACPI support) from official 9.0 amd64 UEFI
 image works fine, same applies to the latest i386/amd64 9.0 images
 from https://nycdn.netbsd.org/pub/NetBSD-daily/netbsd-9/latest/
 (latest versions combined UEFI/BIOS boot into one image) or latest
 current (HEAD) images. So, it seems there is no point to boot with the
 -2 option since it causes some hardware initialization to fail.
 Nevertheless,  I believe the initial issue on a blank screen is
 unrelated and probably caused by the framebuffer driver(?). Likely the
 system boots properly though under the hood. It can be verified by
 adding dmesg=YES to rc.conf and checking /var/run/dmesg.boot messages
 after (by mounting partition in different system). Still, I would
 recommend trying the latest builds from nycdn first, since I had a
 similar issue in previous releases too. Also, I don't have NVIDIA
 graphics, only Intel graphics.  Maybe disabling nouveau (or even
 i915drmkms) can help here, but I am not sure if that can be done
 without recompiling the kernel manually.
