cactus5552 Posted August 11, 2015 Share Posted August 11, 2015 I have a clevo P375SM (Sager NP9390). I use clover with OSX yosemite 10.10.4. Sometimes when my laptop boots up It shows a black screen. Other times it works fine (I have a 3 monitor setup, and OSX detects and uses all 3). They are my laptop display, a Displayport to DVI adapter for one monitor, and HDMI for another. If the system boots to a black screen, I have to hard restart the system, and go into clover's boot options and go to graphics patching options and checkmark the "Inject Nvidia" checkbox, IT will load and boot then, but HDMI does not work. It's kind of random when it works and when it doesn't. I've tried PCIRootUID=0 and =1, and GraphicsEnabler=Yes and No. Has anyone else had this problem? It seemed when i ran the installer to install OSX, all 3 monitors worked fine.

cactus5552 Posted August 11, 2015 Author Share Posted August 11, 2015 Where would I find those? Nvidia's web site? Link to comment https://www.insanelymac.com/forum/topic/307535-clevo-nvidia-geforce-gtx-780m-4gb-issues/#findComment-2159492 Share on other sites More sharing options...
Allan Posted August 11, 2015 Share Posted August 11, 2015 Nvidia Web Driver updates for Yosemite Nvidia Web Driver updates for El Capitan Note: The optimus feature is not supported in OS X. So, you only can use the Intel HD graphics card.

cactus5552 Posted August 11, 2015 Author Share Posted August 11, 2015 I got it. Thx. Note: my CPU GFX does NOT show up anywhere (even when i modded the BIOS). So the only GPU i have to work with is the 780. Another question, On real Mac's they have 2 gfx cards.. Is it a different way they do that ?

JahStories Posted August 11, 2015 Share Posted August 11, 2015 ohhh i haven't noticed Optimus, sadly as Allan said, it's totally incompatible with OS X... you can only use integrated GPU. Apple is using a totally different way to use it's dual Gpu switching. 1 Link to comment https://www.insanelymac.com/forum/topic/307535-clevo-nvidia-geforce-gtx-780m-4gb-issues/#findComment-2159505 Share on other sites More sharing options...
