INTEL HD 3000 ISSUE AFTER UPDATING TO 10.9.3

[bluenote56]

Hi, I updated to 10.9.3 from a 10.9.2 perfectly working system and since I have a mixed one (Sandy Bridge/Z77) I supposed I just needed the usual modified kexts I've always used to make HD 3000 work. (I put the HD 3000 id in the info.plist of AppleIntelFramebufferCapri and AppleIntelSNBGraphicsFB and it always worked till now).

This time this trick doesn't work and I could not boot the system for a kind of "semaphore related" error. So I tried with org.chameleon.Boot.plist with "<key>IGPEnabler</key>

<string>Yes</string>

<key>IGPPlatformID</key>

<string>00301000</string>"

after restoring the original kexts. No way. 

So I had to go back to 10.9.2 with time machine. I have the same problem with a 10.9.4 system on another HD.

I'm surely missing something or making something wrong. 

If you can give me some advice it could be great.

 

Thanks
