Thanks MaLd0n. I am an impatient type... and while waiting for your answer tried several things. NVidia Web Drivers (the default MacOS drivers work fine for my Asus GeForce GT730 - just not for waking from sleep) tried disabling AppleIntelCPUPM in clover (read it was not required for Haswell Processors) and was not sure that a patch USB3 was applied - so tried to add a kext patch.
In any case, when I tried to wake from sleep with the power button - same thing. If I wake using the USB keyboard - it gets power, but nothing else - and the screen does not turn on. When I use the power button the USB keyboard never gets power.
So it would seem that either the graphics card and / or USB are preventing waking from sleep. I am now going to revert back to how I was when I used the RunMe.app and try waking using the power button again. Pretty sure I did that but it did not work.
I really appreciate your help, how can I go about troubleshooting this - any steps you would recommend. Anything I can look at in the output of the RunMe.app?
When you created the DSDT.aml file for me, I was still trying to get OSX HighSierra installer running - and was not concerned about graphics, but I am so pleased with the setup now - everything is working pretty much flawlessly except the onboard Wi-Fi of my desktop that I have not tried - it is hard wired to Gb ethernet - so that's not a concern for me.
Getting sleep working is my main concern -I appreciate any help / tips you might have. Thanks.
