Hello you guys,

 

I am currently running OSX 10.9 perfectly on my Dell 7520 laptop (Will set up Yosemite on another partition these days  :wub: ). 

 

The problem that still exists is that I am unable to use either the HDMI or VGA port because the switchable graphics (Radeon HD 7730m & HD4000) are not supported. That means that the system is currently running on HD4000, but the Radeon would probably do much better. So now to my question: 

By setting the discrete 7730m as primary graphics card in BIOS (no clue how to get to that function, maybe modded BIOS?), could I get it running? This would provide me the feature to use a second monitor. The 7xxx-series should all be supported by OSX, but I have not really heard anything about the 7730.

 

My system specs:

Core i5 3rd Gen

HD4000 / Radeon HD 7730m(?)

OSX 10.9

 

Thanks in advance :)

You can't. It's not supported by OS X AFAIK. You should focus on disabling it with DSDT edits.

Hm okay, thank you. :)
What I wanted to achieve is a second monitor and/or the ability to use a beamer at school. A workaround would be a USB to HDMI/VGA/DVI adapter, but the video quality is not that good I think. Does anyone have experience on this with OSX?

I don't know, but hopefully if you disable your gpu than you can use your intel hd for hdmi. I use my HD 4000 for power a second monitor and as far as I can tell, man, works like a charm on very high resolutions. I am very satisfied with it.

I think I need to flash another bios then since the dell one does not offer any additional features to the boring usual ones. :/

I installed a modded BIOS, so now I can choose to use either switchable graphics, the dedicated gpu or the internal HD4000. setting the gpu as primary card will probably brick the laptop, so I keep my fingers of it. now, that only the IGFX is set as primary, I should be able to edit the AppleIntelFramebufferCapri kext and get hdmi/dvi working, right?
