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.

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)

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.

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.

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?

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

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
