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.

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?

I´m now giving a go to Yosemite (pure vanilla install, chameleon based).

Right now, the install goes smooth, the installed system does not boot (graphics related).

Will give you more details when i solve the problem.

Regards.

UPDATE: Everything working under Yosemite, will post instructions and files once i get some free time.

Here we go (here are the instructions and drivers i have gathered from the community for our beloved Toshiba L750 and Yosemite).


First the instructions to create an USB installer for Yosemite:

1. Download OS X v10.10.2 [Mac App Store] and Right-click "Install OS X Yosemite" → Show Package Contents → Contents → ShareSupport → Double click to mount "InstallESD.dmg".

2. Once "OS X Install ESD" appears, use ShowHiddenFiles to show hidden files.

3. Now you will see an image called "BaseSystem.dmg" appear. Mount it by right-clicking and opening it with DiskImageMounter... Get prepared to use the USB stick with at least 8GB.

4. Open Disk Utility, and format the USB stick by highlighting its icon on the left and clicking the Partition tab, click Current, and choose 1 Partition.

5. Click Options... Choose Master Boot Record. No need to name it (the default's OK), choose Mac OS Extended (Journaled) as its format type. Click Apply then Partition.

6. Select and highlight the volume "OS X Base System", click "Restore" at the top-right, drag the volume into "Source" field, and drag the USB [Untitled] partition (you just created) to the "Destination" field where you will restore the image: click "Restore" then "Erase"...

7. After the process is complete, you'll now have (2) "OS X Base System" present in Finder. Eject the image "BaseSystem.dmg" and close Disk Utility.

8. On the remaining volume "OS X Base System" (USB stick), go to System/Installation and delete Packages symlink.

9. Open "OS X Install ESD" in a new Finder window, and copy the Packages folder to System/Installation folder inside "OS X Base System".

10. Copy BaseSystem.chunklist and BaseSystem.dmg from "OS X Install ESD" and copy it to the volume root.

11. Create a new folder named "Kernels" in System/Library on the USB stick. Use Pacifist v.3.2.17 to extract "kernel" from "OS X Install ESD/Packages/Essential.pkg [/System/Library/Kernels/kernel]" and place "kernel" into System/Library/Kernels/ location.

That´s it.

Now the second part, download the attached zip file and uncompress it.

Remember to create a new serial number in smbios.plist for you with Lizard or any program that can create serial numbers for hackintosh (you have to use MacBookPro11,1 as base model).

Install chameleon on the flashdrive Yosemite has been deployed.
Overwrite the flashdrive´s extra folder with the one in the zip.

Boot and install Yosemite.
On reboot, select again the flashdrive for booting, but this time select your internal disk as startup disk on Chameleon Boot.
Once you arrive to desktop, install chameleon on internal hard disk, overwrite the extra folder.
Install AppleHDA Toshiba.kext to S/L/E (use the provided kext utility), erase the original AppleHDA.kext.

Reboot.

Enjoy!!.

Files for Toshiba L750 Yosemite: https://www.sendspace.com/file/fjhziv

PD:

All files are compatible with Mavericks, just change in org.chameleon.boot.plist:

<key>Kernel</key>
<string>/System/Library/Kernels/kernel</string>

To

<key>Kernel</key>
<string>mach_kernel</string>

Locate a patched osinstall for MBR, then you can follow the guide after replacing the file.
