Sorry I have another question.

What needs to be changed on the kext for it to work when osx is updated.

For example what do I have to change in the kext I used for 10.9.3 if I upgrade to 10.9.4.

Thank you

You just have to re-add ID's in AMDRadeon5000Controller.kext and AMDRadeonX3000.kext, repair permission on S/L/E and rebuild the cache (sudo touch /System/Library/Extensions) and reboot.

 

I just did it for my 5450 after 10.9.4 update and it worked fine. Another solution is to keep a copy of the mods Kexts and install them after every update (in case of the graphics drivers are updated but useless if it's a Security update) but the drawback is that you'll end up with severely depreciated kexts when we'll got 10.9.58 Update :hysterical:

 

The ultimate fix is to create a DSDT with correct infos for your GFX and you'll never be annoy anymore with .plist edits. Dr Hurt should be able to help you with this as I'm not skilled (or smart enough :rolleyes: to understand these damn DSDT way !)

Thanks. I tried using the 10.9.3 kext once I updated to 10.9.4 but I still did not get the gfx to work correctly.

The process of I followed was:

1. Download the combo update.
2. Run the update and let the pc restart.
3 . Once restarted run kext wizard which run throughout once.
4. Install the gpu kext that worked with 10.9.3 with kext wizard.
5. Check if launcher gfx works correctly, if not reboot and try 4 again.

Thanks

The best solution, beside DSDT; is always to edit the new kexts installed by the update because you're up-to-date with the latest drivers and hopefully, you should benefits their enhancements and optimizations.

 

So I'd say, :

1/ Run the Combo update or use AppStore to get the latest version of OS X.

2/ Restart and let the update finish

3/ Install every kexts you need such as AppleHDA edited kext  etc. but in case of GFX, try first to edit info.plist of the new Kexts (which in our case are AMDRadeon5000Controller.kext & AMDRadeonX3000.kext)

4/ Run Maintenance tools from Kext Wizard and repair permissions on E/E and S/L/E and the whole disk is also a good option (after System Update, lots of files have incorrect permissions anyway).

5/ Reboot once again and it should be OK.
