Hi,
I am getting a bit desperate trying to resolve sleep issues in 7490 in Monterey/Big Sur.
I would be grateful for help or pointing in the right direction.
Thanks!
MY GOAL:
* either fix sleep issues
* or mitigate these issues by disabling sleep completely
* understand why WIFI is so slow? Currently only getting 250Mb on DW1560 with all kexts and patches.
PROBLEMS:
Due to COVID, I worked for 2+ years from home. I built myself a desktop Hackintosh workstation as that was really the only viable option long-term, without shelling $3000+
Now I am expected to work from the office twice a week. I need a Hackintosh laptop to maintain my workflow. I bought this 7490 two weeks ago with the sole purpose of converting it to a budget MacBookPro.
Everything that is important works pretty much out-of-the-box. The only missing piece is:
* WIFI - got it working with DW1560 but slow. Can't make Intel 8265NGW working again at all. And I had much better speed (650Mb) when I tired initially in Monterey.
* SLEEP - this is in fact critical to me in a laptop, as I can't imagine sitting in the 3h meeting and when it goes to sleep - I need to hard-reset it to work again. Absolute showstopper. Even after installing CAFFEINE laptop still switches off the screen when closing the LID and the sleep problem occurs.
* Laptop also does not SWITCH-OFF, but that's like the least of my current problems. I however think it is linked to the sleep issue.
MacOS installed fine and booted OK. Pretty much all was working until I started testing sleep.
I tested by inducing the sleep mode using:
* the LID
* Fn+INS
* Sleep option in MacOS
* MacOS timeout when running on battery.
The behaviour was pretty much the same each time:
* The laptop's keyboard lights up
* CPU goes into overdrive
* The screen remains dark and I can only switch it off by holding the power button.
* It also does not switch off - when I shut down the OS, it looks like it's shutting down but the power light stays on - until, again, I hold the power button.
When the laptop is plugged in to the mains and the screen times out (goes dark) - it wakes up fine. I guess in never actually goes to sleep - it just blanks the screen.
Any other option: LID, Fn+INS, Sleep in the menu - same results as listed above, even when plugged in.
TROUBLESHOOTING SO FAR:
* I tried both BIG SUR 11.2.3 (to build my own USBPorts.kext) and MONTEREY 12.3.1. Same behaviour.
* I tested both BIOS versions: 1.24.1 and 1.16.0. Same results, although on 1.16.0 I can't make WIFI work after downgrade. (downgraded from 1.24.1 - some modules like Intel ME did not downgrade!). I reverted back to 1.24.1
* I disabled the hibernation as per @Jake Lo guide and followed @Hervé BIOS settings recommendations.
* I've seen a similar problem on the forum but the solution provided did not help (https://osxlatitude.com/forums/topic/17079-latitude-5490-no-sleepshutdown-under-monterey/)
* I tried in OC 8.0 (after updating all KEXTs). I then dialled it down and tried in OC 7.5 and OC 6.8 - updating KEXTs along the way as Airportitlwm refused to work without updating it (and LILO as well). I always cleaned NVRAM between reboots.
* I tried with both USBInjectAll.kext in Big Sur and with my own USBPorts.kext in Monterey - no difference.
* I have no devices plugged into the laptop except Logitech trackball (to navigate on the screen as sometimes touchpad was not responsive)
* I used various SMBIOS: from MacBookPro 14,2 to MacBookPro 15,2 - no difference.
* I tried several different EFIs and started to build my own - but that's way to many variables to consider. Would take me 6 months.
* Tried both Kabby Lake-R and Coffee Lake CPU IDs (recommended settings in Dortania guide) - same results.
Currently running on EFI with OC 0.8.0 from @Jake Lo, posted here:

Got pretty much same results on each. Sometimes had to change configuration to make the iGPU work or to make the WIFI work.
LAPTOP:
Latitude 7490
BIOS: 1.24.1
i5-8350U
32GB RAM (2400MHz) - perhaps too much RAM?
Audio: Realtek ALC3246
SSD: Samsung 970 EVO Plus 1TB NVMe - perhaps incompatible NVMe?
WIFI: DW1560 M.2 WiFi 802.11AC. Working but quite slow. I also have Intel 8265NGW but can't make it to work anymore with Airportitlwm.
My IOReg file attached.
