Many people with nVidia lost QE/CI after the 10.5.3 update.
The way to bring it back is very simple :

- Open the info.plist of the injecter (/system/library/extensions/xxxx.kext/contents/info.plist)

- Find the line with :

- Replace that number with 0

- Save to desktop, move the file back over the original one, overwrite (you'll need to authenticate)

- Launch the terminal and type those 3 lines to repair permissions :

You can now exit and reboot, QE/CI will be back

PS : this guide assumes the "usual stuff" about GFX support is already OK (right kexts with right dev IDs, injecter correctly set...)

THANK YOU VERY MUCH!

Working perfectly as on 10.5.2 with my Gigabyte 8800 GT!

Thanks a lot.

No success here

NVDANV50Hal.ktext
NVDAResman.ktext
NVinject.ktext
NVinjectGo.ktext (I guess - sorry I'm newbie - this is the one what really counts)

what else should I do yet?

Problem solved: I've installed NVInstallerV41, and luckily it works again

Damn... It didn't work for me... still no QE/CI active with my 7300GT.

I've tried them all. Downloading NVInstaller choosing only nvinject 256 (No first driver package, the 90Mb one, Right?)

Then I've edited the .plist file as you describe, replacing the number with 0.

No luck...

Changing IOProbeScore didn't work for me either using a 8600 GT

Doesn't work for my 8800 GTS 320MB either.

Works great for me on integrated GeForce Go 7400 . Thanks !

derailed_spark,

i also have an integrated GO7400. What drivers are you using?

I've tried nvinject and nvkush but i always get a blank screen after boot.



Thanks!

RM

Just want to clarify: Does below only apply to NVinject.kext directory or all NV*.kext directories?

I got it too! Please tell us what drivers you have used!
I've tried NVinstaller_V.41 on my kalyway 10.5.1 updated with kalyway10.5.3_Combo and i got a blank screen. No internal LCD nor external VGA works. Thanks

It's not work for mine: GF 880GTS 320/320? Why?

Thx it's working

This method DID NOT work for me either: EVGA 8600GT

works perfectly here (8600M)! thank you

Got my CI and QE back on my 7300GT (512 meg) by first dragging all drivers that start with GeForce from /system/library/extensions to the desktop and then installing the NVinstaller_V.41 package.

I did not check any extra options... just the injector and the driver for the first card (256 MB).

Rebooted, and all was good.

This also fixes the 70017 error in DVD Player.app


cheers

Thanks I am able to verify this technique works.

I: moved GeForce*.kext and NV*.kext from /system/library/extensions to a backup folder.
2. Deleted all the kext above (move to trash) required authentication. (at this point, I am basically trashing all the old kexts, so do not restart!!)
3. Run NVInstaller41.. I selected to install NVInject 128MB.
4. Restart.

Card is a NVS 285 dual head.

I am using the NVInjectGO 0.2.0 right now , but i tested most titan based injectors , all of them work for me. My notebook is ICH7 besed. I even use the internal display + an external one , clone and mirror working with-out problems. I tested so far Tiger 10.4.8, and Leo 10.5.2 and 10.5.3 , all with no issues.
The onboard card is a GeForce GO 7400 TurboCache card ( 128 dedicated ) and it should be 256 in total ( acording to specs ) , but System Profiler only shows 128 , no matter what kext I load.

Great Solution! Thanks a lot!

Still won't work. Blank screen, nor external vga monitor. Waiting 4 Scottdangel V.5

Hello,

This is what i was looking for.
The first sugestions did not work for me but the second.....
Thank the lord.

I: moved GeForce*.kext and NV*.kext from /system/library/extensions to a backup folder.
2. Deleted all the kext above (move to trash) required authentication. (at this point, I am basically trashing all the old kexts, so do not restart!!)
3. Run NVInstaller41.. I selected to install NVInject 512MB.
4. Restart.

works great for me
i am running 10.5.3 combo update from 10.5.2 kalyway with a vanilla kernel on a;
P5K premium wifi
Q6600 @ 3400 Mhz
4 x 2 Gb GEIL @ 950 Mhz
EN8600 GT 512 Mb

All programs work fine (adobe cs3, office 2008, aperture, final cut)

Thanks for the guide!Now my 7300gs works on 10.5.3:D

Basically, I tried the way Iamalittlepepper post. I tried the V41 and V52. Both give me blank screen.
Then I booted into safe mode and everything works fine. I tried again and again and still no luck. Until recently, I can have everything booted into 1024x768 mode. However, it is so ugly on my Dell 2550FPW which can run 1680x1050.
Any help?

it works NOT with my foxconn 7900gs ....

that worked on my hackintosh':

klick



important is to choose n.41 not n.51 ^^

Didn't work on a 7900GS here.

wtf???

what happens?

do you realy take n.41 and not n.51 ... with n.51 it does not work, either with n.52...

For anyone still suffering from booting to a blue screen,this worked for me. Boot into single user mode (-s) and perform the following:-


/sbin/fsck -fy
/sbin/mount -uw /
rm -rf /System/Library/Extensions/NV*
rm -rf /System/Library/Extensions.mkext
rm -rf /System/Library/SystemConfiguration/ApplicationEnhancer.bundle
reboot

I was able to get back to my desktop in a native 1024x768 mode and reload nvinstallerv41.
QE/CI Now working!

so many solutions..... but not a single works for me.

i am using xfx 8400 gs 256 mb. tried



and making string 0 method.

both of the methods failed. any more idea guyz?? cheerz

I have the same problem, blue scren, nvidia GO 7950, 512 RAM
How to instal NVInstallerV.41.pkg

Blue Screen too, with the NVInstaller 4.1 method,
i do a check to see wich kext are the bad ones, Geforce.kext, NVDAResman.kext.

Please, stay on the topic, this is not a thread for support of XXX installer or something, ask about this in the relevant topics. If it doesn't work, it's most probably because your injecter/kexts were already not working before the update, because it's not set up properly.
Here is a thread about nVidia installation.

Thanx it worked for me. Its been driving me crazy

Krazubu instructions worked perfectly for my hack! I'm using Kalyway 10.5.3 with a 7300GT Thanks!!!

Did not work for me, unfortunately.

Thanks for your efforts!

Kudos for Krazubu

His advice works perfectly. No need to install additional inject.kext.

QE: Supported


Finally video back normal again.

Also for me worked, on a 7900gs
Thank you very much.

This technique did not work for my 8600GT 512MB Card after updating Kalyway 10.5.2 (vanilla) to 10.5.4. But I installed NVinstaller v.52 and that set everything straight.

Edit: NVinstaller .52 also works for 10.5.5.

That worked for my 8400GS as well. The first post in this topic did not.

Thanks!

Thanks for the tip. After several attempts using other kexts, I installed NVInstallerV41 and huzzah!
