I got my hands on MackBook and tried to put GhostBSD on it but run into a hold/freeze after

kldunload cant find file nvidia-modeset

kernel: Failed to add WC MTRR for [0xa0000000-0xafffffff]: -22; performance may suffer

Any suggestions as to how to proceed are welcome.

In your photograph, the most relevant line is probably:

Starting Desktop (Intel DRM).. Please wait..

Does your model have Intel HD Graphics 3000?

Hi,
wouldn't say so
lspci -v | grep -r vga gives
VGA compatible controller : Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) (prog-if 00 [VGA controller])

Thanks, 2nd Generation Core Processor Family Integrated Graphics Controller also appears for a MacBookPro8,3 and according to EveryMac.com, all four models include Intel HD Graphics 3000.

Of the six models at https://everymac.com/ultimate-mac-lookup/?search_keywords=MacBookPro8,2, which one matches yours?

Hi,
@grahamperrin
Thanks again for your guidance.
When I try to boot in single user mode in step when I should enter pathname of shell weather i stick with /rescue/sh or type /bin/sh i get the following
cannot read termcap database;
using dumb terminal settings.

After that I tried to use kldload radeonkms but i get:
kldload: can't load radeonkms: No such file or directory

I stumbled upon https://bugs.freebsd.org/bugzilla/show_ ... ?id=247112

Sorry, my mistake. (I thought I tested the steps with an ISO, in retrospect it seems that I tested the steps with an installation.)
