Can't make sleep working on HD530 - HP EliteDesk 800 G2

[hoaug]

Hello everyone,

 

Over the past few days, I’ve borrowed a Mini PC — the HP EliteDesk 800 G2 — with the following specs:

CPU: i5-6600

iGPU: HD530

SSD: SN730 + an unknown-brand SATA SSD

Wi-Fi: BCM4352

 

I attempted to Hackintosh it, and everything works quite well except for wake after sleep. The system won’t wake up once it enters sleep mode. I’ve done a lot of research in places such as:

I first tried installing Sonoma, and am currently using Ventura. I’ve spent over a full day reading guides and troubleshooting, but I probably lack the expertise to solve this issue. So, I’m reaching out to ask for your help. Here's what I’ve tried so far:

 

Attempt 1: macOS Sonoma

- Sleep worked fine, but the machine couldn’t wake.

- Suspecting the issue might be with the following DeviceProperties:
AAPL,ig-platform-id=00001659, device-id=26590000, enable-max-pixel-clock-override=01000000 and SMBIOS set to iMac19,1

- I removed Sonoma and decided to try Ventura instead.

 

Attempt 2: macOS Ventura

- Same issue: sleep works, but wake doesn't.

- I experimented with DeviceProperties like picture (also tried device-id=12590000) + SMBIOS iMac18,1 but had no success.

 

 

Attempt 3: Hibernate Mode

- I tried using hibernatemode=25, but the system would crash immediately when entering sleep.

- I suspected RTC issues and tried the following fix:

+ Used RTCMemoryFixup.kext with boot args: rtcfx_exclude=58-59,B0-B3,D0-DF - still not Wake and auto restart.

+ Replaced those with SSDT-AWAC-HPET-RTC.aml (from the first guide above).

+ Also enabled DiscardHibernateMap = True and HibernateSkipsPicker = True.

-> Not working at all.

 

Attempt 4: HDMI Cable and Monitor

- Thinking the issue might be related to my HDMI 2.0 cable and 180Hz Full HD monitor, I patched BusID

- The patch correctly detected HDMI connector type, but unfortunately, wake still didn’t work.

 

Boot args used in all 4 attempts: -v debug=0x100 keepsyms=1 alcid=11 -btlfxboardid igfxonln=1 -igfxhdmidivs igfxagdc=0

About BIOS Settings: I followed the initial guide, except that I couldn't enable Intel ME directly because it doesn't appear in the BIOS. But I was able to enable Active Management, so I think Intel ME is already enabled

 

I’m at a loss for what to do next. If anyone has experience with this kind of issue, I would truly appreciate your guidance. Thank you so much in advance!

 

Here is my EFI and DSDT, thank you.

fix typo

@kinhhoang161 Sky Lake and Kaby Lake in macOS do not wake up from sleep mode, requires discrete AMD RX graphics.

@HmO Thank you for replying to me. That’s truly unfortunate news. Is there really no other way besides installing a dedicated graphics card? Like maybe using hibernate mode or something?

No, there isn't, if it goes into sleep mode the HD530 doesn't show any image again...

 

I had that iGPU for a few months years ago and the same thing happened to me. 😄

@PoMpIs So, so, so sad… haizz. Everything works, but only Wake says no. Thank you for the information-I'll just forget it
