Anyone using iMac 15,1 for 4790k + Z97X + Nvidia Graphic Card in 10.11 ElCapitan?

[MacOrDie]

Maybe this is not necessary, but I am trying to get the iMac 15,1 profile running on my system (i7 4790k + Z91 + NVIDIA) with ElCapitan. The problem is that after boot, there is no video. The system is functional, I can get sound, the CD-ROM to eject, just no video.

I found this great post from 10.10 which addresses the blank screen
Memory corrupted after longer sleep
But I didn't understand the part about the SSDT and can not any files that match in clover or on the desktop.

If you know of a guide or how to do this, please post

Thank you!

See problem #4: http://www.tonymacx86.com/graphics/161256-solving-nvidia-driver-install-problems.html

I am using that profile with my main build.

Thank you. Worked like a charm.... now I can get back out of sleep mode and access all the processor states! I made the correct edits, just didn't relink/redo the kernel cache. I could write a quick script to make these edits. Do you think it would benefit anyone?

If you made that script it would be wonderful!

Here is the script and instructions.

1. Download file from this post
2. Open a Terminal and type the following (assuming you downloaded with Safari)

cd Downloads
sudo ./fixit.sh

or use nano to make your own script with a copy/paste of code below. This code makes a backup of your plist just in case.

#!/bin/sh

# Reference: http://www.tonymacx86.com/graphics/161256-solving-nvidia-driver-install-problems.html
#
# This script automates the modification of AppleGraphicsDevicePolicy.kext so that the
# monitor does not go to end of sleep at boot sequence when using NVIDA card.

id="/usr/bin/id"
awk="/usr/bin/awk"

tmp=`$id | $awk -F" " '{print $1}'`

if [ "$tmp" = 'uid=0(root)' ]; then
echo "You are root!"
tool=/usr/libexec/PlistBuddy

# Real Path
plist="/System/Library/Extensions/AppleGraphicsControl.kext/Contents/PlugIns/AppleGraphicsDevicePolicy.kext/Contents/Info.plist"

#Backup plist, just in case
/bin/cp $plist $plist.backup

echo "\nModifying $plist \n"

echo "Current Values"
echo "=============="
tmp=`$tool -c "Print :IOKitPersonalities:AppleGraphicsDevicePolicy:ConfigMap:Mac-42FD25EABCABB274" $plist`
echo "iMac15,1 = $tmp"
tmp=`$tool -c "Print :IOKitPersonalities:AppleGraphicsDevicePolicy:ConfigMap:Mac-F60DEB81FF30ACF6" $plist`
echo "MacPro6,1 = $tmp"

echo "\nSetting Values to none"
tmp=`$tool -c "Set :IOKitPersonalities:AppleGraphicsDevicePolicy:ConfigMap:Mac-42FD25EABCABB274 none" $plist`
tmp=`$tool -c "Set :IOKitPersonalities:AppleGraphicsDevicePolicy:ConfigMap:Mac-F60DEB81FF30ACF6 none" $plist`

echo "\nVerfying Values (should be none)"
echo "=================================="

echo "iMac15,1 = $tmp"

echo "MacPro6,1 = $tmp"

echo "\nRebuilding Kernel Cache"

Is this the way it's supposed to look when it executes the script?

I'll reboot now and see what happens.
Keeping my fingers crossed.

 

[mhjeff]

It worked!
Thanks so much.

What is the benefit of using iMac15,1 over 14,1/14,2? I'm curious as my upcoming build is 4790K + Z97X + nvidia

Nothing I have found. I have gone back to 14,2 because I don't want to mess with the problems of the 15,1 every update. Some who has a better understanding needs to create a Clover kext patch to take care of the patching to none on the fly.
