Allan Posted April 8, 2015 Share Posted April 8, 2015 I think yes, try this: http://www.hackintoshosx.com/files/file/3711-amd-radeon-r9-270-series/ Follow this guide: [Guia] Habilitando QE/CI AMD Radeon R9 270 If you have an OS X operating normally, I advise create another partition to this new version, and follow the guide above. If all goes well, you'll help us a lot. But if it does not work, we'll wait for the developer to create another method for us. Link to comment Share on other sites More sharing options...
Maniac10 Posted April 9, 2015 Share Posted April 9, 2015 Mine has been working fine since 10.10 with Clover by setting the framebuffer and ports amount manually ("Radeon" and "4" respectively). I'm running today's 10.10.3 release btw. 1 Link to comment Share on other sites More sharing options...
UnDeaDAmP Posted April 9, 2015 Author Share Posted April 9, 2015 Mine has been working fine since 10.10 with Clover by setting the framebuffer and ports amount manually ("Radeon" and "4" respectively). I'm running today's 10.10.3 release btw. Ohhh... I asked over on r/Hackintosh on reddit and they told me, the 270X works out of the box, but the 270 needs a framebuffer edit and such. Is this true? (2GB Model from Gigabyte) I think yes, try this: http://www.hackintoshosx.com/files/file/3711-amd-radeon-r9-270-series/ Follow this guide: [Guia] Habilitando QE/CI AMD Radeon R9 270 If you have an OS X operating normally, I advise create another partition to this new version, and follow the guide above.

Yes, I've been asking because I'm trying to decide whether to pull the trigger on buying the card or not. Its a great price to performance card for its performance in gaming i've seen and heard. Considering the 2GB Gigabyte Model. Link to comment Share on other sites More sharing options...
Allan Posted April 9, 2015 Share Posted April 9, 2015 For framebuffer editing, see this: http://www.insanelymac.com/forum/topic/294315-radeon-r9-270x-framebuffer-issue/ Link to comment Share on other sites More sharing options...

Maniac10 Posted April 10, 2015 Share Posted April 10, 2015 Depends on the exact model. As I said before, mine works OOB with graphics injection turned off but it works better with the Radeon FB and I need to specify the ports amount, else it will be set to 2 or 3. Other models with different ports have problems booting OS X OOB but that can be solved thanks to Clover's on-the-fly binary patcher. Just add the patches on the config and you're ready to go. 1 Link to comment Share on other sites More sharing options...

Ahh... okay, thank you. Much appreciated. Just to clarify, it will work, but the graphics card will be much better utilized if i inject graphics with it. And do you mind if i ask what card you have specifically? A reference unit or a Gigabyte one or an ASUS one, or what? Link to comment Share on other sites More sharing options...
Maniac10 Posted April 11, 2015 Share Posted April 11, 2015 Yes, in my case it works fine without graphics injection but it performs better by enabling it and specifying the Radeon FB (just enabling it is not enough, you've got to override the default FB). Of course the results may differ depending on whether you've got graphics power management working properly and the SMBIOS profile selected. For the 270/270X the ideal Mac model would be the MacPro6,1 as it comes with a similar model. Still this is just a performance adjustment and it should work fine with any other modern Mac model with an AMD card. This is my graphics card: Sapphire Radeon R9 270X 2GB Link to comment Share on other sites More sharing options...
Pavo Posted April 11, 2015 Share Posted April 11, 2015 SMBIOS is not meant for gfx selection, it for chipset and CPU selection mostly Link to comment Share on other sites More sharing options...

VirusX Posted April 18, 2015 Share Posted April 18, 2015 most 270X will work OOB with one monitor. But as soon as you want multi-monitors, the aforementioned edits in clover (injection yes/no, framebuffer patches etc) probably have to be applied. My MSI R9 270X 2GB works with DVI and HDMI after I injected Radeon Framebuffer Link to comment Share on other sites More sharing options...
Pluskat5000Schiffe Posted November 2, 2015 Share Posted November 2, 2015 SMBIOS is not meant for gfx selection, it for chipset and CPU selection mostly Sure however AGPM.kext is depending of the SYSdef set in SMBIOS. So not gfx selection but surely it has impact on graphics power management. Link to comment Share on other sites More sharing options...
Slice Posted November 6, 2015 Share Posted November 6, 2015 No, OSX can't perform power managements on PC Radeons. Link to comment Share on other sites More sharing options...
Pano_78 Posted November 11, 2015 Share Posted November 11, 2015 No, OSX can't perform power managements on PC Radeons. So the card will run at full power all the time? I´m torn between a Used Sahphire 7970 and a new 270x. Link to comment Share on other sites More sharing options...
