Thank you for your help. I really appreciate it. I will give a try this night when I will come back from my work. As soon as possible I will give you a feedback

Hey, I just managed to get my HD5970 working by using posted kexts and AtiConfig: Zonalis. Got my 2 monitors hooked up and working. The only problem is that my HWMonitor is reporting ~50*C on first core (with is ok), and up to 80*C on the second. Any idea who could be the cause of this?

No idea. On my board, there is only one fan for both gpu with one heat sink. The second gpu is usualy hotter than the first one when both are running.


Your second GPU should not be hot as it's not used with that kext. Maybe you managed to activate both ? lol ?!


5970 is a real heater by the way... On summer it's the hell in the room. But it runs good.¥†


That said, I would check for dust in it. If you do so, get some thermal paste and pads before to achieve that.


FYI it's quite cold in here (like 15ºC) and my temps are GPU1 75ºC/GPU2 62ºC while stressing the card with Unigine Heaven Benchmark 4.0. I just cleaned my board few weeks ago.

No news, good news ? :lol:

I suppose cleaning is long overdue, but I just went through a basic mode of UH Benchmark 4.0 and while maintaining ~50fps temp stayed at no more than 80*C. 

Normally I wouldn't worry with those results, but while idle GPU goes down to 40-50*C on Windows, on OSX it stays at about 70, as if it was still under stress.

Is your card cooling down while idle? And is there a way to check if 2nd core is active (as much as I doubt it), or maybe a way to under-clock my GPU on OSX?

I agree with you. I did not check temp after stress. I will.


For the second gpu, if you did no edit to the provided kext, the second gpu is inactive for sure.


To underclock your gpu, you will have to go through bios edit and flashing. I don't know software way to achieve that on osx. I would not recommend to flash you gpu bios.


I noticed that some windows settings for hardware remains even if you boot to osx. The temp you report are after reboot from windows or cold boot ?

I guess the difference is fan control.


You can flash your BIOS to enhance it but still risky...


My 5970 runs usualy hot, that does not worry me more than that.

Romaincs, I've tried your kext and my system could not finish the booting process. Ran with -v and found out that the system stops after it recognizes there is a AMD cypress card on slot 1.


My motherboard is GA EP45-UD3P, installed ##### with ##### option.


Could you shed some light on this? Thanks.

Thanks for reading,


Yes, I forgot to mention that I edited "AMD5000Controller.kext" as "ATI5000Controller.kext" and "AMDRadeonX3000.kext" as "AMDRadeonAccelerator.kext".


I'm not realy familiar with FB things. In ML, when I used AtiConfig=Uakari and added ID under cypress, which FB does it used ? I'm asking myself if they did not moved the FB in another kext like X4000 one.... ?


Hun what? 


Could you be a bit more precise please?

Do you mean renamed AMD5000Controller.kext" to "ATI5000Controller.kext" and "AMDRadeonX3000.kext" to "AMDRadeonAccelerator.kext"? 


If that is the case you also added/created an info.plist and version.plist for each? I ask because in 10.9 those 2 files do not exist in AMD5000Controller.kext. 

Where did you get the Info.plist from?



And what is FB, FaceBook?

I should've read through the entire thread before wasting 4 hrs on the kext modification on my own. Thanks romaincs for your great effort!

      I have browsed thru all forums and all threads for this card but apparently my system is still something special. With some cumbersome effort (none of the simple one-click ##### and other USB-Installers methods ever worked for me) I managed to install Sierra 10.12.5. However when booting is nearly finsihed I get the famous black screen which can be recovered by quickly unplug/plug the DP monitor cable leading finally to a proper initialisation of my 290X. 

      1.) RadeoDeInit is on, without this patch the screens stays dark forever
      2.) Booting with iGFX never works for me, I always get memory allocation errors during boot until I disable the Intel graphics completely.
      3.) I am on Clover 4318, newer version do not make any differences.
      4.) I am using a System Configuration for an Imac 14,2. Most other configs do not make difference either.

      I have not started again the nightmare of Framebuffer patching (as I remember from Yosemite) and I think it will not help as the card is recognised by Sierra but just not initialised.

      Hi all
      I currently use an NVidia 760 with four displays: 1 x 4K; 2 x 1920x1200; 1 x 1920x1080.   This mostly works, but I am considering replacing it with an AMD GPU - likely a Radeon 7970 - for two reasons:
      I would like to add a fifth monitor, maybe even a sixth; I get small stutters and slowdowns with my NVidia, using both Native and NVidiaWeb drivers.  It is a lot better than it was with my NVidia 980Ti, but it's still not perfectly smooth as it should be, especially when I have a full screen video playing while also doing UI movements like Swipe Left A Space or Mission Control.  
      I have just been told that it should be possible to access all display outputs on an AMD 79XX GPU, possibly requiring a custom SSDT and/or radeonDeInit?  I've only ever had one AMD GPU and that was 8 years ago so I am not experienced with them.  My NVidia 980Ti has five outputs, but can only use four at once.  But I believe AMD's EyeFinity does allow it to use them all as separate displays.
      Before I buy the GPU, I'd be most grateful if anyone could confirm that it should be possible to run five or six simultaneous displays on a card such as the ASUS HD 7970 DirectCU II (6 x DP outputs) or XFX AMD Radeon HD 7970 (2 x mini-DP; 1 x HDMI; 2 x DVI).  With one display being 4K @ 60fps and the rest 1920x1200 or 1080P.
      I have Googled on this a while but haven't yet found anyone discussing connecting more than four monitors to an AMD Hack  I did see that the late-2013 Mac Pro (which uses 2 x AMD FirePro GPUs) states it can support "up to 6 Thunderbolt displays".  So I know the OS can do it, it's just a question of whether a particular GPU can, and in a Hack setup.
      Thanks very much

      Hi Insanlymac’ers.
      I have a super deal on a WX9100 Radeon Pro Vega, but I only have 12 hours to repond, or it’s gone.
      Is this card able to run in High Sierra and take advantage of all 16GB ram?
      Thanks in advance!

      Hi guys, i'm trying to help a friend of mine trying to install osx(possibly high sierra) on his pc with the following specs: 
      Amd fx8350 
      Asrock 990fx extreme 3
      8gb of fury Kingston ddr3 ram(2x4)
      Radeon hd 7950
      128gb ssd( crucial m550)
      A couple of hdds I don't remember the brand(maybe a seagate barracuda and a dumb old disk for data)
      We tried to install it using the regular clover+high showers installer but we couldn't get it to reach the installer, then we tried osx-amd(don't know if i can talk about it there, sorry if i can't) and we still couldn't get to the installer.
      Is there a guide i can use to install osx in that machin, i tried to search in the forum but i couldn't find it.
