Here you have two updated files to solve the graphic problem in 10.9.3 and UP and also Speedstep/Graphicspowermanagement.

 

Just replace those two files in extra folder: smbios.plist and LegacyInjectorToshiba.kext

 

Now we can update safely.

 

Enjoy.

 

PD: Remember to create your own serial number with Lizard.

Attached Files

I have updated changing those files to 10.9.4 and I got a black screen. Do we have to install old 10.9.2 drivers too?

No Resistor, we use the updated 10.9.4 drivers, we use the update as it is. Be sure you repair permissions and erase com.apple.kext.caches before reboot if you manually installed the 10.9.4 drivers.

 

A question:

 

Are you using the files i have shared before, DSDT, drivers,etc?

 

The idea for the fix came from here, i explain it: Apple has changed on 10.9.3 the way the drivers attach to the graphic cards, and for that it uses this kext: AppleGraphicsDevicePolicy.kext, if your SMboardproduct is there, will load, if not, black screen.

 

In the link i provide, they suggest to patch the driver, while my approach is to  change/update our SMboardproduct to match one of the driver and update the SMproductname.

 

Also i did update LegacyinyectorToshiba.kext to add the new smbios information on it.

 

You should not have any graphic problem now with apple stock drivers as both modifications will allow to load the drivers, please elaborate your extra folder contents and update method.

 

Regards.

I updated to 10.9.4 and my extra folder with legacy inyector and smbios, generate my own serial with lizard and black screen. Perhaps i have had to repair permisions?
