So with that as a road map maybe we can get some of this patch working on 10.12 with dual monitors or 3 monitors

Just look here.

I have explained here, how to get framebuffers from 10.x running under macOS 10.12 aka SIERRA. Hope, that helps.

the 290x is a bit harder than other amd cards to get working that's why i made the thread

Thanks so much for posting this! I was trying to fix dual monitor issue on el capitan for days..

I followed Mork's instructions and patched the AMD800Controller but had no luck.

 

Anyone else has any other idea?

 

Saphire R9 390X

can you give me that patch you made so i can test it 

I will post tomorrow what I did, not sure if it'll work for anyone though.
 

Edit: 

 

Here are the changes that I made, let me know if I messed up anywhere:

 

I originally had it working for El Capitan with the following patch (Clover):

<key>ATIConnectorsController</key>
  <string>8000</string>
  <key>ATIConnectorsData</key>
  <string>000400000403000000010300120403030004000004030000000101001102010100040000040300000001020021030202000400000403000000010400220504040004000004030000000105001000050500040000040300000001060020010606</string>
  <key>ATIConnectorsPatch</key>
  <string>000800000402000000010200220504030004000004030000000101001204010100040000040300000001020020010306040000001402000000010300110205040004000004030000000104001000020500040000040300000001050020010606</string>

Here is the Original Baladi framebuffer for AMD8000Controller (290X and 390X) in Sierra:

00040000 04030000 00010300 00000000 12040303 00000000
00040000 04030000 00010100 00000000 11020101 00000000
00040000 04030000 00010200 00000000 21030202 00000000
00040000 04030000 00010400 00000000 22050404 00000000
00040000 04030000 00010500 00000000 10000505 00000000
00040000 04030000 00010600 00000000 20010606 00000000

So the modified buffer string should be: 

000800000402000000010200000000002205040300000000000400000403000000010100000000001204010100000000000400000403000000010200000000002001030600000000040000001402000000010300000000001102050400000000000400000403000000010400000000001000020500000000000400000403000000010500000000002001060600000000

In all the new patch should look as follows:

<key>ATIConnectorsController</key>
  <string>8000</string>
  <key>ATIConnectorsData</key>
  <string>000400000403000000010300000000001204030300000000000400000403000000010100000000001102010100000000000400000403000000010200000000002103020200000000000400000403000000010400000000002205040400000000000400000403000000010500000000001000050500000000000400000403000000010600000000002001060600000000</string>
  <key>ATIConnectorsPatch</key>
  <string>000800000402000000010200000000002205040300000000000400000403000000010100000000001204010100000000000400000403000000010200000000002001030600000000040000001402000000010300000000001102050400000000000400000403000000010400000000001000020500000000000400000403000000010500000000002001060600000000</string>

But it didn't work for me, although I think we are on the right track. While testing with the new patch I noticed that one of the screens flashed white for less than a second every 3 minutes or so, but I haven't had more time to continue troubleshooting.

 

Hopefully someone can help us out.

Hi wardoc,

 

I tested your patch on my system with Yosemite (10.10.5) and had the same mixed results as we many other patches: it works with 2 DVI screens but I get random freezes with always the same error message in the log:

 

WindowsServer: Surface testing not allowed for .......

 

I patch with Clover, Card ID etc. is well recognised, graphic accelerations is working fine.

 

Can I expect an improvement with El Capitan for my card?

 

thanks, Haegar.
