Solved: OSX Lion 10.7.4 not recognizing GTX 550 ti after multibeast

Hi all,

I'm trying to get a hackintosh running with a mix of some spare parts I had and a couple new parts. It boots fine and runs but only gives me 1024x768 resolution and reads the graphics card as just a 3mb nvidia card.

It's taken me about 6 hours to get to this point but now I'm stuck.

After 3 installs trying different settings to find the perfect ones that get this comp booting in the least amount of extra steps, I Have it almost perfect except for this graphics card problem.

All the steps done during the last clean install:

-Installed lion 10.7.4 using unibeast and everything went great and the first boot read the video card fine and gave me the full resolution.
-Ran multibeast and installed the dsdt for my mobo, repair permissions, 64bit graphicsenabler=no, and nvidia drivers for 10.7.2+
-Rebooted and got the boot0: error
-Followed the boot0 error guide and rebooted and was then able to boot the os but I wasn't getting full resolution or graphics card detected.

and that's where I'm stuck at now.. everything else seems to be fine and there's no errors or anything to search and these video cards seem like they work fine in lion for everyone, so I don't know what the problem is.

Any suggestions?


Hardware list:
Processor: Intel Core i7 950
Mobo: GIGABYTE GA-X58A-UD3R (rev. 1.0) (F6)
Vid card: Gigabyte GeForce GTX 550 Ti Windforce
Ram: Corsair XMS3 CMX12GX3M3A1333C9 12GB 3X4GB DDR3-1333 CL-9-9-9-24 Triple Channel Core i7 Memory Kit
HDD: Seagate Barracuda ST1000DM003 1TB 7200RPM 64MB SATA 6Gbps


Thanks in advanced!

I think I got the problem solved for now. The solution that worked for me was:

- install 10.7.4
- multibeast user dsdt, nvidia drivers, etc
- download this: http://www.osx86.net/view/1816-geforce_gtx_550_ti_for_lion_-_opengl-efi_...html but only install the NVDAGF100Hal.kext
- make the change to the kext that was suggested by Zero06Si on page 3 of comments on that
- download OSX86Tools (http://code.google.com/p/osx86tools/)
- download and install more updated lspci (http://www.osx86.net/downloads.php?do=file&id=1643)
- reboot
- generate efi string for the 550 ti using osx86 tools using the steps listed by martineztherock on page 1 of comments on the first link
- add the generated hex code to the org.chameleon.Boot.plist using the code
<key>device-properties</key>
<string>generated hex code goes here</string>
- download and install 10.7.4 drivers from nvidia (http://www.nvidia.com/object/macosx-270.00.00f06-driver.html)
- reboot

and now card is detected, all resolutions are available and openGL seems to work with 33.5fps in cinebench
