GeForce GTX 550 Ti for Lion / OpenGL/EFI String 1.0


About This File

Here it is, a whole day of work just to get this to work properly. Full QE/CI support for Lion for the GeForce GTX 550 Ti with 1 GB memory. You need to copy the files in their respective folders as depicted in the compress folder in this download. I had to add the EFI string to the chameleon boot loader plist file in order for the Natit (nForce Enabler) to work. The file is included and if you simply want to keep yours, just copy and paste the bottom and the string onto your org.chameleon.Boot.plist files in the Extra folder. Also included is a working copy of the OpenGL to work with this files, downloaded from here. Proper credit goes to all of those people who worked and created this files. All I did was change the Dev ID to work on my setup and put them together. So here it is, if you have questions, feel free to ask, but please only for this card. Works with 10.7.1 as well.

will this work with the following config....

Intel dx58s0 (recent upgraded bios from win7 HD) Intel i7-920, Corsair 6GB triple channel ram, wd 1tb sata, pioneer dvd dl rw

Currently i have a GT9500 but the analog port does not drive my either my display or tv properly so i need to use a dual Dvi and thought a EVGA gtx 550 ti 1gb?

Also, does anyone have the DSDT file for the this mobo. I got everything to work but i had to set the energy saving to off because the system does not come out of sleep, and i am assuming that its DSDT related.

Note: I used E1000e for onboard Ethernet and AppleAzilla for onboard Audio

Hi Martineztherock.

Thanks for your attention and time dude.

I am Spanish, English translator.

I will install a Mac OS X Snow Leopard, version 10.6

I will do as described on the website:

http://{censored}.blogspot.com/2010/04/iB{censored}-MB{censored}-install-mac-os-x-on.html

NVIDIA GeForce GTX 550 Ti (1024 MB)

My biggest problem is that my graph is a 550Ti and not here GTX drivers for my version.

I also suggest in the forum, I have to:

After edit kext yes.

Thanks for your time, carlos

Mokarim: to install these kexts, use kextwizard or KB{censored}. Either of the two will work but I prefer kextwizard. Repair permissions and reboot.

Neoblack: Yes dual monitors work in 10.7 and 10.7.2, I'm currently working on getting dual monitors to work in 10.7.3

As of now, I have Lion updated to 10.7.3 with dual monitors, sound, and full QE/CI. These kexts did not work for me so you will need to find your graphic card device id and put it in your NVHAL100.kext.

I'm running 10.7.3 and with a GeForce GTX 550Ti and I am unable to get multiple monitors to work. As well the graphics a very choppy.

@Zero06Si could you go into further detail how you got yours to work? and run smoothly?

rudy2358, What you need to do is download the bundle from here. ONLY USE THE NVDAGFHAL100.kext <- very very important. When you download the folder, go to:

System -> Library -> Extensions -> right click NVDAGFHAL100.kext -> show package contents -> contents -> info.plist

Scroll down about mid way ish until you see:

IOPCIPrimaryMatch

0x124410de

delete that 0x124410de and type this in its place:

0x124010de&0xffc0ffff

So it will look like this by the time you finish:

IOPCIPrimaryMatch

0x124010de&0xffc0ffff

Close the info.plist and restart your computer. Do not blame me if you get a kernel panic or anything. This has worked for me and a friends computer and it should work for yours.

@txsw1mmer: It depends on the motherboard you have. Use MB{censored} from the {censored} website to reinstall your audio kext. For example, I have the Asus P8P67 Pro motherboard, so I use ALC892 audio. I used MB{censored} to reinstall the kext, restarted my computer, and sound was working again. Hopefully it works for you. If you guys need help feel free to add me on my Skype since I'm generally always on that.

What do you mean it goes to sleep? Does it not start? Or does it start and then go straight to sleep mode? Go to settings -> energy saver and make sure that the computer sleep is turned off, if that's what you're asking.

I got sleep problem too. After load NVDAGF100Hal.kext, see at -v mode, then the monitor turnoff then the PC sleep. Cause my system can't wakeup from sleep then I could not do anything. but, I did install driver from nvidia website which made for 10.7.3 and I'm on 10.7.2 (iATKos L2), not the kext in here. With kexts in here my pc did not recognize anyway, NVDAGF100Hal.kext registed but not work at full screen resolution. My system is Dell 490 workstation. Any idea would be appreciate!

@mcarthy1991: I solved the problem and figured it out what cause the monitor turnoff after install these kext.

The wrong HEX string in org.chameleon.boot cause turnoff the monitor.

You need to make one for ur system. Try to use OSX86Tools make one. I follow this guide

But, even though we use OSx86Tools, it would generate wrong HEX string if your system can not run LSPCI (the button beside the "Add EFI string" button). If the LSPCI can't see your system info how can OSx86Tool can make the right Hex string one. Right?

In my case, Dell 490 workstation upgraded to CPU xeon E5345 and everything else stay the same as 4 years ago, LSPCI could not run right on Lion, but it could run fine on Snow Leopard 10.6.8. So I restore my backed up system then use OSx86Tools make the Hex string for this card, MSI GTX 550Ti 1024MB. Put it in boot.plist. (No kexts need edit because my card is the NVIDIA's reference card (1 fan)). It run, full QE/CI.

Haven't test HDMI, but I haven't need it yet.

Cinebench give

- OpenGL ~22 fps

- CPU ~6 fps

The result just same as under Windows 7 Ultimate x64 on It's low because the PCI-E x16 v1.0a on the motherboard. GPU can't load over 69% every test. Sad!!!!

Hope my experience can help you.

What did you put for "my dev-string here"? Also, you just did that and the BCLK thing? Mine seems to work with the dsdt, but I think it can be better

I just added the Device-String into my boot.plist. Nothing else. Download OSX86Tools and run it.

1. Select "Add EFI Strings/Boot Flag"

2. Choose "GFX String"

3. Select Graphics Card and scroll down to Custom Geforce

4. Give any Name

5. Select your Amount of RAM

6. Select your Connection (Display Output)

7. Copy and paste the Hex String into your boot.plist like mentioned above.

Sidenote: OSX86Tools are outdated. It uses com.apple.boot.plist instead of org.chameleon.boot.plist. If you select "Import String to Boot Editor" at Step 7, it'll wrote the Hex String into the com.apple.boot.plist in /Library/Preferences/SystemConfiguration Folder. If you wish OSX86Tools should do that for you, remove com.apple.Boot.plist from /Library/Preferences/SystemConfiguration and rename your org.chameleon.Boot.plist in /Extra to com.apple.Boot.plist before you run OSX86Tools. After applying just re-rename com.apple.Boot.plist in /Extra to org.chameleon.Boot.plist and you're done.

another note: I install Lion 10.7.2 iATKOS L2, not the retail downloaded from app store, maybe the guy who made this install disc moded NVDAGF100Hal.kext with wildcard so it can support many GTX card so far.

No cigar on this one. I have an nVidia GeForce GTX 550 Ti and I followed the instructions EXACTLY, but I still have 1024 x 768 ONLY, so it isn't working for me.

Motherboard : MS-7728

CPU : i5-2320

NIC : Realtek RTL 8168/8111

Audio : Realtek ALC 887

Any ideas?

hi, martineztherock

I am a fresher. I installed 10.7.4 in vmware 8. I modify the "com.apple.boot.plist" file in extra folder. And copy the 4 files in the right position. But the system tells "/System/Library/Extensions/AppleGraphicsPowerManagement.kext" installed incorrect. Can not be use. Neither dose the "Natit.kext". How Can I DO? Please help me. Thank you.

@martineztherock

thank you very much for that file! it works perfectly for me.

The only thing is that I would like to use dual screens. right now it only works with DVI and NOT hdmi. Would this be possible to use DVI and HDMI for two screens?

Let me know if you find a way.

thanks again.

I tried to get my onboard sound to work so i used a file from the net and screwed everything up. It actually changed the video card to a 440 and now wont start up..... watch out what you guys use from other users!

@Martineztherock

So i finally got my Hackintosh running again after lots of hours of frustration....

The only problem that i have is that i had to add to the org.chameleon.Boot.plist the following string:

PCIRootUID=1 ncpi=0x2000

I added that next to your arch=i386

Why do i need to add this to enable my graphic card to load?

Its also not running anything that has flash... and i updated to the latest flash too.

I tried to disable the acceleration on the flash video's but i cant even click the box my mouse just kind of disappears over the video's.

Also i noticed that my screen glitches a tiny bit sometimes.

When looking under the folder "About This Mac" Graphics says nVidia GeForce GTX 550 Ti 1024MB.

But then when i go into Displays, the only screen size that i may access is 1280x1024.... my screen can take 1680x1050 60mhz.

So i changed the string in your org.chameleon.boot.plist that was 1280x1025x32 and changed that to 1680x1050x32....but it does not change anything.

The weirdest of it all is that the first time that i setup my GPU it was running perfectly.

But then i added some Kext extensions to my system file for the audio i think and thats when stuff started to go south.

But anyways so now i have a fresh clean install and the only two things I've installed is your GeForce .plist with your 4 Kext files and ive installed the realtekRTL81xx.Kext

Up to now everything seems fine other then those GPU issues. I will wait to install audio. If anyone has good suggestions please feel free to comment.

Also if anyone has or knows of any tweaks i can make to improve my system, please feel free to fill me in since i am a "green horn"! ;-)

Thanks
