    Question Internal Intel Graphics on MacBook Pro 11,3 (with Nvidia 750M)

    Hi,

    I would like to give it a last try. Was anybody able to get the Intel graphics card working on a Haswell MacBook Pro (11,3) that is also equipped with the Nvidia 750M? I am not even looking for a dual solution, just want to see if I can get the Intel graphics working at all. I tried various options but without any success.

    Thanks,
    Kjano

    Hi, see http://lists.gnu.org/archive/html/gr.../msg00442.html and http://forums.macrumors.com/showthre...3#post18576213.

    This enables the Intel GPU, but I haven't gotten the old outb commands in grub to switch the gmux to work yet, so you'll have to use GfxCardStatus in OS X to switch to the Intel card.

    I can switch to the Intel GPU -- but only see a black screen, no matter what. Any advise? Thanks!
