Hi ! I'm glad to say that With your help, El Capitan it's now installed on my dell vostro 3300. Thanks ! I use the files posted by @black.dragon74 (DSDT/SSDT) it seem that the nvidia GPU is correctly off at boot. Unfortunatly, i have some issues : Battery performance are poor The sound chipset are not initialized. I think that i need to customize the DSDT and SSDT files, but i doesn't very know how to do that. Do you think that it's possible for you to help me if i attach my CLOVER repository ? Many thanks. OliCat

Hi ! Ok, I can get graphical installer now ! I perform the installation and i'd do a report about the patched DSDT for disable optimus GPU. Thanks all for your time and your support OliCat

Hello Jake, Yes, that's what I did. No success, graphics still not loaded. Perhaps there is a problem with my config.plist. OliCat

Yes, El Capitan. I've downloaded this kext http://www.insanelymac.com/forum/files/download/208-1st-gen-intel-hd-graphics-kexts/ for the post install. Can you tell me how i can inject this FakeID ? I've injected the fake id : no success OliCat

Ok. Now, the boot are stuck on "bluetooth family...": the graphic intall does not start... I can get OSX Utility with adding the -x bootflag. OliCat

Hi, It's OK : PCH_LVDS (0x000e1180) : 0x80200302 (enabled, pipe A, 18 bit, 1 channel) OliCat

Hello, Nope, because of the nvidia hybrid card, i finally installed Linux. Yep, I have tested that: no success. However i had the same issue with Maverick that i'd solved. I'm unable to remember how I had done. @ all, thanks for your time OliCat

Hi, Arg! alway the same issue.. OliCat

Hi ! Long time ago I installed (Maverick) but today with El Cabitan installer i stuck on "still waiting for root device". Probably I'd used a boot parameter i've forgoted today. Anyway, this is the dump. Thanks origin.zip

Thanks for you're reply @black.dragon74 ! I redo an installation and I send you this OliCat

Hello ! Thanks to the community that allowed me to install OSX on two laptop dell (E6420 and E6220). I have a vostro 3300 with a nvidia hybrid graphics card (310M). It is not possible to disable it in the bios. Is there a possibility to disable it via DSDT? Thank you in advance for your feedback. OliCat
