I just fixed my problem with integrated graphics, and now everything is working, but I cant help to want to get my 7790 working with this. What is so special about the 7790 that every other ATI card works except for this one? Is there any possible way of enabling this? Thanks!

Dont know if this will really help, but it is (sort of) directly related. I do hope you find it useful.

Also did you try doing a search for your card in the search bar (upper right hand corner above your name)? You might want to try that if you havent already, there might be threads dedicated to your topic already which you could read up on.

I hope these two suggestions help. Sorry I cant be of more assistance, Im a newbie and not technically minded, still in the learning process (very much so).

Thanks. I've looked at all of those threads and searched everything I could, but none of those threads really have answers. Anyone else?

I did a google search also - nothing came up

https://www.google.com/search?q=ati...fficial&client=firefox-a&channel=np&source=hp

googled: ati 7790 kext

there were a few webpages in foreign languages which seemed to mention the card, but I couldnt find anything related to any kexts when looking at their webpage(s). it does seem to me that the 7790 most likely isnt supported by OSX nor are there any kexts available. if that card was supported it would be in the list here at TMx86 (http://www.tonymacx86.com/graphics/92952-list-confirmed-radeon-hd-7xxx-series-10-8-3-a-21.html)

maybe there are kexts available and I didnt find them. wanted to let you know my findings

I hope everything works out for you SOON!

hopefully someone who really knows will reply to your post :thumbup:

Thanks for your help! Sadly, it seems that even though this card is so similar to other 7xxx series, it isn't supported for some reason. :(
 
me too :(.
Waiting for new 7xxx kext.

How did you get it to even recognize that it was a 7790? Mine just says unknown and 3mb of graphics on a PCIE slot. Nothing about the 7790. At least that's something. So your's isn't accelerated either. It should show 1gb.

Anyone else have any ideas since these cards are so similar?

What Mine says:

Code: 
Chipset Model:	Unknown  Type:	GPU
  Bus:	PCIe
  PCIe Lane Width:	x16
  Vendor:	ATI (0x1002)
  Device ID:	0x665c
  Revision ID:	0x0000
  Kernel Extension Info:	No Kext Loaded
 
Same problem here man did alot of research can't find for HD7790 :(
 
I have exactly the same problem with this card but I've been digging around the kexts and inside the Personalities section of the X4000.kext the device id for the 7790 is actually in there (665C1002), which is very strange.

All I get when booting is Unsupported device!, then at the end of the boot the message "Couldn't load AMDBonaireAccelerator" message. I've tried adding the id to the AMD7000Controller.kext to no avail.

It would be good if someone would help us guys out with this issue and I would be willing to help however I can as this is a fantastic card.

ANY help would be appreciated.

I'm in the same boat, have done the same and ended up with similar errors.

Here's my research in hope of someone can find it useful.

From AMDRadeonX4000.kext we can see that AMD cards are categorized into 4 groups and the group that HD7790 is in is called "AMDBonaireGraphicsAccelerator". While cards in other 3 groups are supported, cards in this group are NOT supported (yet).

The group of AMDBonaireGraphicsAccelerator has these device id: 6640, 6641, 6650, 6651, 665C, 665D.

The other 3 categories are:
AMDPitcairnGraphicsAccelerator with device id (6800, 6801, 6806, 6808, 6810, 6819)
AMDTahitiGraphicsAccelerator with device id (6790,6798,679A,679E,6780)
AMDVerdeGraphicsAccelerator with device id (6820,6821,6825,6827,682D,682F,6839,683B,683D,683F)

For more reading about these AMD's codenames (Bonaire, Pitcairn, Tahiti and Verde), see http://en.wikipedia.org/wiki/Radeon_HD_7000_Series.

"
  • HD 7790 model is designed more like the 7800/7900 models rather than the 7700 featuring 2x primitive rate instead of 1x which is found in the other 7700 cards[SUP][11][/SUP]
  • Bonaire is in the Caribbean Sea, Malta is in the Mediterranean Sea these parts are reverse rebranded out of the Sea Island Series to appear in the 7000 Series this year
"

First thought:
The device ID for 7790 (665C1002) is present in the original AMDRadeonx400.kext in the group of AMDBonaireGraphicsAccelerator, but not in the original AMD7000Controller.kext.

If 665C1002 is added to AMD7000Controller.kext's Info.plist, then Mavericks will stall at start up with error message: Couldn't allow class "AMDBonaireGraphicsAccelerator".

I tried moving 665C1002 in AMDRadeonx400.kext from the group of AMDBonaireGraphicsAccelerator to the group of AMDVerdeGraphicsAccelerator, Mavericks still stalls, but the error message about "AMDBonaireGraphicsAccelerator " is gone.

Maybe we can try moving 665C1002 into the other two groups to see if it works.

Second thought:
The reason that 7850 can be made supported by injecting device id is because 7850 is in a group that is supported (AMDPitcairnGraphicsAccelerator).
If the group that 7790 belong to is not supported, it just wont work by simply injecting device ID of 7790 into those kext.

So the ultimate question is, does Mavericks support the group of AMDBonaireGraphicsAccelerator / Bonaire at all?
