Hi

A few day’s ago I decided fo upgrade my macOS Sierra to High Sierra on my system:

Gigabyte X99P-SLI
Intel Core i7 6800K
Geforce GTX 780 3GB
32GB DDR4 3000MHz
GodoRam 256GB SSD (SATA)
(USB Keyboard and Mouse)

It’s take some times but without problems High Sierra install and boot up on my system. Everything works ok except sleep. When I click apple menu then sleep computer has no problem to go sleep and wake up (at least now). But I have set to put computer in sleep for 15 minutes on inactivity. And here is a problem. Computer goes to sleep but every a few times it hangs between sleep and wake mode. It’s mean computer is working and indicating that SSD is working, display is in sleep mode (no signal), OS is probably hang because no sound when clicking cmd+q. For a few minutes optical drive give sound typical when you turn on computer. In this case I can only shutdown computer and boot it up again. (It will never goes sleep, and I can’t wake it up)

I’ve tried a different version of kexts, clover, typical solutions for this motherboard on the web (Download and paste to EFI partition) but results are always the same.

On sierra computer was working perfectly fine. I use macOS on PC since 10.6, but now I cant find solution to solve this issue.

I give up, back up on Sierra :)

The same on Catalina, any solutions?

For the first time it goes sleep fine, for second time it's not working - it hangs on black screen (no signal on display). After reboot sleep is working again but only once.
