Symptoms for 10.5.7 with Ati HD4870 (Asus in my case):
-after installing the Natit.pkg everything works fine
-on 2nd reboot you get blank screen
-boot with -x (safemode) and reinstall Natit.pkg
-everything works again...until 2nd reboot when u get blank screen
:hysterical:

I know this is happening to other people (from what I read in comments), and they all said they can live with it:)), well...I couldn't.

To fix this annoyance I have prepared a startup script which will run with root (or some root equivalent) credentials and automatically and silently install the Natit.pkg on each boot, to fix the blank screen after 2nd boot.

-create a folder named ATIFix in /Library/StartupItems
-Copy these attached files in there:
ATIFix
StartupParameters.plist

-create a folder ATIFix in /Library
-copy Natit.pkg in there

-Install Natit.pkg and reboot to allow OSX to repair permissions on the StartupItems
-reboot twice to test

Have fun:)

Hey, Are you using the DVI2VGA to connect monitor? I also using a Asus 512M 4870 with two DVI and a S-Video. Not sure what's the problem caused it do not work in the second time.

Having same problem and it's really annoying, I must admit.

I'll try what you posted and feedback later on.

Btw, I also have Ati HD 4870 and Asus (P5QL actually)

I thought it was something to do with my OSX install so am reinstalling (I just started getting into osx86 yesterday) - but now I read your post it makes sense.

Thanks mate!

EDIT:

Works wonderful - like a charm! Thanks a bunch.

I have a 4870 and do not know how to apply the drivers to get multiple resolutions. Could someone explain that?
Thanks.

ATI4800Controller.kext
ATIFramebuffer.kext
ATISupport.kext
LegacyATI4800Controller.kext (this kext injects your cards ID automatically no modifying plist)
video.zip ( 903.47K ) Number of downloads: 127

Read through this thread and yes its different depending what version of card you have and what Chameleon your using and what version of OSX
Start at the beginning


HD48xx use the same kext (drivers).

Remember to boot in safe mode (look it up but it should be typing -x on the Chameleon screen selection)

Good luck!

No. Try the steps above, or search the net on how to refresh the boot caches (I think it could work without the steps above, although I haven't tried it).
