It's work !!! Thanks, now I try to imagine how can use the DVI and VGA port in the same time ? My main monitor is connected in DVI, I want to have a second monitor connected in the VGA port ? Is it possible ?
Thanks

Biz,
HD3000 can do up to two displays. (HD4000 can do 3). On the Z68 boards, the VGA is hard-wired to the DVI port I believe, to give you an analog version of the DVI output. This won't help you much ... I think you need to use a combination of HDMI+DVI or HDMI+VGA. To validate that DVI==VGA, a quick and easy thing to do would be to purchase a DVI->VGA adapter dongle like this

Otherwise, you will need to patch AppleIntelSNBGraphicsFB.kext. As far as I understand it, OSX does not natively support VGA, so you need to define the connections/ports for the framebuffer to drive the correct outputs.
I am summarizing what I have read on other posts, so this might not work and I certainly have not tested it.
In AppleIntelSNBGraphicsFB.kext, you need to patch the AppleIntelSNBGraphicsFB binary using a hex-editor like HexFiend, or use Clover's kext patching feature to search and replace values.
The default framebuffer table in the kext is:
0102
0400 1007 0000 1007 0000 // No of Connectors (04)
0503 0000
0200 0000 3000 0000 // connector 0503, Laptop VDS (0200) - built-in display
0205 0000
0004 0000 0700 0000 // connector 0205, DVI (0004),
0304 0000
0004 0000 0900 0000 // connector 0304, DVI (0004),
0406 0000
0004 0000 0900 0000 // connector 0406, DVI (0004)
You could replace that with a VGA definition or change one of the others to be an HDMI definition, e.g:
0102 0400 1007 0000 1007 0000 // No of Connectors (04)
0602 0000 0200 0000 3000 0000 // connector 0602, VGA
0205 0000 0004 0000 0700 0000 // connector 0205, DVI (0004),
0304 0000
0008 0000 0900 0000 // connector 0304, HDMI (0008),
0406 0000 0004 0000 0900 0000 // connector 0406, DVI (0004)
I am not sure that the above edits are complete, or even correct - you will have to do more research and testing. There's something else to do with the 5th word-values (3000,0700,0900,0900) that may need edits - read the 2nd link posted below. Once you have patched the kext, you need to use kextutility to install, reboot etc.
