... Is there a BIOS update for your machine?

I tried..to update using the latest official Bios from MSI. USB Key ready with new bios inside. Flashing process starts...everything was fine and finally a few secs later, at the end, the last line, this appears : A1 Error : BIOS does not support entire ME Firmware update

damn, but why :/ (bios update "works", only the ME firmware not...)

You may have an idea about this error ?
Otherwise, I'll probably find how to solve it someday.
Thanks for your help

Finally, it's working !!

I tried few things making modded Bios to enable ME FW update. Well, It was a failure...

The answer was already here, in the forum, in this thread : http://www.tonymacx86.com/mavericks...-store-content-access-problem.html#post733874

It was really easy ... just replace an hex value in AppleIntelFramebufferCapri extension binaries.
The idea is the following : Skipping a part of the procedure of AppleMEClientController.
48 85 C0 test rax, rax => 48 31 C0 xor rax, rax
=>
Hopper Disassembler v3 demo

Using Hex Fiend, edit binaries(v8.24.11) and replace this :
48 89 83 98 00 00 00 48 85 C0 0F 84 02 03 00 00 48
to this :
48 89 83 98 00 00 00 48 31 C0 0F 84 02 03 00 00 48

At next boot, no more DRMStatus error and AppleIntelHD4000Graphics.kext is properly loaded
IntelAccelerator appears in IOReg, QE looks ok

I guess/hope MEI device is not really essential....

I've got stuck at the same message, if this is the key to all I will kiss you!, I've tried so many things to get the HD4000 working, nothing worked, always the "DRM Message" whatever IGPlatformID I've used. I got a Patched DSDT and Power Management seems to be working, I'm on a IVY bridge without MEI interface.

Update, PATCH OK, message gone, problem solved after two weeks!
