UEFI/BIOS settings - Most important.

OS Type - Other

 

CSM Support - Never

 

For Install:

 

Create a Penboot of OS X El Capitan 10.11.0, and install Clover in UEFI mode. The process of install is the usual.

 

For install OS X and boot I used these boot-args: 

-v nv_disable=1

Post-Install:

 

After entering in OS X, I've installed Clover in UEFI mode and upgrade OS X for 10.11.5 version using a Combo Update.

Keeping the boot-args.

 

Now you can download and install the last version of Nvidia Web Drivers, using NVIDIA Web Driver Updater.app

 

After that, change the boot args:

nvda_drv=1

About USB 3.0 recognition and speed.

 

I have the proper USB 3.0 recognition and speed, using only these methods.

 

DSDT patches.

EHC1 to EH01

EHC2 to EH02

XHC was not necessary change it, this device comes with this way (name) natively.

 

I used the @Pjalm patches (Intel 9) and (USB Power).

 

And I used the RehabMan's kextsFakePCIID + FakePCIID_XHCIMux

 

What works:

 

SpeedStep and Power Management - Ok

QE/CI - Ok

USB - Ok and in full speed    :w00t:

Trim for SSD - Ok

Audio - (ALC1150) Ok - I use AppleALC for this

HDMI video and audio - Not tested, 'cause are used DVI instead.

Ethernet Port - Ok

Sleep - Ok

 

Big thanks to:

PJALM and RehabMan - for DSDT patches, and kexts.

Mieze - For Ethernet kext

vit9696 - for audio stuffs

Micky1979 and fantomas1 - for Web Drivers updater tool
