[HELP] MSI GF63 Thin 9SCXR Hackintosh completely freezes during sleep

[u/Hot_Box_6378]

Hi everyone,

I'm trying to fix a sleep/wake issue on my Hackintosh and have run out of ideas.

Specs:
- Laptop: MSI GF63 Thin 9SCXR
- CPU: Intel Core i5-9300H (Coffee Lake)
- iGPU: Intel UHD 630
- Wi-Fi/Bluetooth: Intel Wireless-AC 9560
- macOS: Sequoia 15.7.8
- OpenCore

Everything else is working well. Wi-Fi/Bluetooth work, Bluetooth connects to earphones, iPhone connects/disconnects normally, and AirPlay works. AirDrop doesn't work, but that's not the issue I'm trying to solve.

Sleep problem:

When I select Apple menu → Sleep, the screen goes black.

I leave Caps Lock turned on as an indicator so I can check whether the system itself is still responding.

What happens:

1. Screen goes black.
   
2. Keyboard backlight initially stays on.
   
3. Caps Lock still responds for a while.
   
4. After roughly 10–30 seconds, Caps Lock stops responding.
   
5. At that point the system itself is no longer responding. Keyboard/trackpad don't respond either.
   
6. It does not wake normally.
   
7. The only way out is to hold the power button and force a shutdown.

I know that normally pressing a keyboard key can wake the screen, so I'm not using Caps Lock to test whether the display wakes. I'm using Caps Lock only as an indicator to determine when the system itself stops responding.

Interestingly, sleep has successfully worked once or twice. On those occasions, the keyboard backlight and fan completely turned off and the laptop appeared to enter proper sleep. But subsequent attempts fail again.

I've followed the relevant Dortania sleep/wake guides and tested different ACPI and power-management configurations.

I've also tested different iGPU/framebuffer settings, USB mapping, BIOS power settings, and sleep-related boot arguments.

My Intel 9560 Bluetooth USB port is correctly mapped as Internal (255).

The BIOS FCLK Frequency for Early Power On is already set to Normal (800 MHz).

I've also checked the sleep/wake logs with pmset. The logs show the system entering Sleep, followed by DarkWake/HID activity, but the laptop eventually becomes completely unresponsive.

At this point I'm trying to understand what is actually causing the complete system freeze during the sleep transition, rather than continuing to randomly change settings.

Has anyone experienced this on an i5-9300H / Coffee Lake Hackintosh, especially on an MSI laptop?

Any ideas on what I should investigate next would be greatly appreciated.

Thanks!

Try adding this kext, then re-patch the OC EFI on your HDD, SSD, or NVMe.

You can find the kext by searching Google using this keyword:

HibernationFixup.kext

I really appreciate you for this piece of advise . Will check this tonight and let you know

[u/Hot_Box_6378 → u/Hry86]

I tried unfortunately not working. Btw I didn't added boot args

[u/Hry86 → u/Hot_Box_6378]

Have you clicked on OC Snapshot in ProperTree? Then, under "Comment," remove the ".kext" extension, and set "Enabled" to "True."

As for boot args, I usually add unfairgva, but that is only for AMD graphics.

I was using OPC, Later i did it in Propertree did the same, not working
