jayee Posted August 3, 2012 Share Posted August 3, 2012 aljazudovic: You need another card that work oob to init Desktop first ( I'm using HD 3000 ), then you can switch back to 6950 and it will work. Not by this kexts, the other one made by Oleg_Tr in netkas forum. Link to comment Share on other sites More sharing options...

If you need any help with 10.7.4 then just post your ioreg | grep ATY ( in terminal ), I probably will be able to help out. Link to comment Share on other sites More sharing options...

tbistone Posted August 8, 2012 Share Posted August 8, 2012 This is extremely interesting to me, would this work on just one 6950? I'm having troubles getting my Sapphire 6950 2GB Card to boot up with Mountain Lion, it just stays on a black screen after choosing from the Boot Menu..

Shameless1 Posted August 11, 2012 Share Posted August 11, 2012 Finally Work for me, i used the modified DSDT and patched kexts by Oleg_Tr. Can you please elaborate. Did you remove the existing ATY_init.kext? How did you installd the DSDT and kexts? I have a 6950 and ML in a VM under windows. I tried ###### but all I get is a kernal panic during boot. Shameless.

Nameless One Posted August 12, 2012 Share Posted August 12, 2012 Can you please elaborate. Did you remove the existing ATY_init.kext? How did you installd the DSDT and kexts? I have a 6950 and ML in a VM under windows. I tried ###### but all I get is a kernal panic during boot. Shameless. VMs don't allow direct access to the actual graphics hardware, they have a custom driver that converts graphics operations in the guest OS to something the underlying OS drivers can handle. What the real hardware happens to be is totally irellevant to the guest OS and it cannot find out what it is anyway. As far as I can remember ATY_init is for enabling recognition of ATI/AMD and Nvidia hardware and as such absolutely useless under a VM. Link to comment Share on other sites More sharing options...
Shameless1 Posted August 12, 2012 Share Posted August 12, 2012 VMs don't allow direct access to the actual graphics hardware, Sorry to be clear, I'm only using the VM to prep the USB installer (and it works great for that), I have another drive I'm using for OSX for and that is what I am having problems getting to work. Shameless. Link to comment Share on other sites More sharing options...

Jakweeze Posted September 7, 2012 Share Posted September 7, 2012 I'm sorry, I don't mean to be a jerk here, but is there any one that speaks english as a native language able to get it working? If so, could you write a step by step guide on how it was achieved with preferably say: A) 1x6950/6970 1xHD3000 (since a lot more people have this combo than the following) 2x6950/6970's I personally run option (A) but could potentially figure out the steps and rewrite it if someone gave clear cut instructions from start to finish instead of a semi jibberish post (again no offense as english isn't your primary language buddy!) Furthermore the downloads are very mismanaged and all over the place, it wouldn't take much effort to clean them up into two downloads only, one for 10.7 and one for 10.8 with appropriately labeled folders in them that say "Step 1" then "Step 2" with kexts or what have you for each step in that folder! 1 Link to comment Share on other sites More sharing options...
iGoodw1n Posted September 11, 2012 Share Posted September 11, 2012 I have Intel HD3000 in my Core i5 2500K and MSI 6950. After installing OS X ML I can boot only with -x flag. What i need to install to disable my discrete videocard. I want to use only intel 3000 GPU. Link to comment Share on other sites More sharing options...
elidoe89 Posted October 14, 2012 Share Posted October 14, 2012 I have one issue, youtube freezes after about 10 seconds, when I move the progress bar it works again then after 10 secs it stops. 6950 on 10.7.5 using the guide on page 1. Link to comment Share on other sites More sharing options...
Phathak Posted December 19, 2012 Share Posted December 19, 2012 Anyone in here got their 6950 working under 10.8? Everywhere on the web people seem to be saying that it's supported but I can't find a proper guide that says how to fully make it work. Link to comment Share on other sites More sharing options...
lidiano Posted January 4, 2013 Share Posted January 4, 2013 Hello everyone, I'm trying to go with the HD6950 video card on my ML compoter in signature, I read your topic but I did not understand much, would you be so kind as to explain how to do (Sorry for my english but unfortunately I speak Italian) Link to comment Share on other sites More sharing options...
moob Posted January 4, 2013 Share Posted January 4, 2013 Hello everyone, I'm trying to go with the HD6950 video card on my ML compoter in signature, I read your topic but I did not understand much, would you be so kind as to explain how to do (Sorry for my english but unfortunately I speak Italian) Hi i'm also italian, 6950 work for me with HD2500 set as primary gpu. Basically run the boot with an intel HD (HD2000/2500/3000/4000 are fine) set as primary card by bios after the login screen unplug cable from intel HD and switch to 6950. In addition to this must be injected also a custom DSDT for the correct recognition of the card. But now I've changed my video card so I can not help more. Attached the DSDT code to add. dsdt_ATY@Gibba.txt Link to comment Share on other sites More sharing options...
