I've successfully manage to run El capitan with system 100% stable
Create your USB install with Chameleon OS X El Capitan
Overwrite the Extra folder from Post Install with Extra folder of your USB
Boot and install
Install Chameleon Enroch in HDD
Install audio setup from Kext folder
Done!!!
Hope you enjoy it
For suspend to work, just disable hibernation mode
A Big THANKS to #polyzargone for all the help on USB drivers and DSDT patch to bypass the "can't find boot device" and #Jake Lo for fixing the Clover patchs to make Battery percentage work.
Update: Now you can use Clover, just install the clover in HDD then overwrite the CLOVER folder with the one attached
