finke Posted August 19, 2014 Share Posted August 19, 2014 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 ). 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 finke Link to comment https://www.insanelymac.com/forum/topic/300363-getting-radeon-hd-7730m-working/ Share on other sites More sharing options...
falanx Posted August 19, 2014 Share Posted August 19, 2014 You can't. It's not supported by OS X AFAIK. You should focus on disabling it with DSDT edits.

finke Posted August 19, 2014 Author Share Posted August 19, 2014 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?

falanx Posted August 20, 2014 Share Posted August 20, 2014 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.

finke Posted August 23, 2014 Author Share Posted August 23, 2014 I think I need to flash another bios then since the dell one does not offer any additional features to the boring usual ones. :/ Link to comment https://www.insanelymac.com/forum/topic/300363-getting-radeon-hd-7730m-working/#findComment-2054701 Share on other sites More sharing options...
finke Posted August 25, 2014 Author Share Posted August 25, 2014 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?
