Hardware
CPU: I7-8550u
GPU: UHD620
RAM: 16GB 2400MHz DDR4
SSD: I don't remember which Samsung SSD is in here but it is fully compatible with no extra work
Wi-Fi/Bluetooth Card: Has an incompatible Qualcomm card. I replaced it with the Lenovo BCM94352Z. Either this laptop has no whitelist, or that specific card is in the whitelist; however, the service manual does not say that this card is compatible so I am assuming there is no whitelist.
Audio: ALC298
4k screen



What Doesn't Work
Fingerprint Sensor
Many of the function buttons (paper display, refresh, airplane mode, lock, switch display, disable camera only sometimes works)
Graphical glitches in games if you pull the mouse to the top or bottom and pull up the dock or menu bar
The USB3 on the USB-C ports is on the ThunderBolt controller, so you will only get hot plug if whatever adapter you plug in only gets USB2, or something else (HDMI, DVI)
I haven't tested it with this version, but on an older version USB-C Displayport/HDMI wouldn't get audio
Sleep doesn't actually put the computer to sleep. The screen turns off and it goes into a lower power mode but the indicator light shows that it is still on
Trackpad never works after an update and requires one or two reboots
Maybe other things I haven't tested
What Works
Pretty much everything else I've tested



INSTALL
Follow RehabMan's guide for installation, you will need a usb mouse.
Pre-Catalina Beta 5 (including Mojave and High Sierra), a different config was needed to boot the installer (config - updates.plist). For Beta 5 and 6 the regular config file has worked better.

After you're done compile it as aml and place in Clover/ACPI/Patched

Compile SSDT-PNLF.dsl from the WhateverGreen download as aml and place in Clover/ACPI/Patched for brightness

Add the SSDT-EC and SSDT-UIAC in Clover/ACPI/Patched for USB



Open terminal and run these commands for sleep
Code:
sudo pmset -a hibernatemode 0
sudo rm /var/vm/sleepimage
sudo mkdir /var/vm/sleepimage
sudo pmset -a standby 0
sudo pmset -a autopoweroff 0

I found the behavior you describe just the same as mine Yoga C930's. Exactly the same spec, no real S3 sleep, and the new sound bar even makes it worser with non functional internal mic. However, I think you can also get the USB3 ports working with a common TB3 hotplug SSDT. (Like any SSDT from this one but remember to match the correct RP0X: https://www.tonymacx86.com/threads/in-progress-ssdt-for-thunderbolt-3-hotplug.248784/)

There are Clover patches for your DSDT afaik, why extracting? I'll check out Catalina with my "new" Yoga 910, looking forward to it! Should be a bliss...

The 910 and 920 are different. The 910 patches don’t work for the 920.

Lenovo Yoga 920 running 10.15.1 with only two question marks left. Thanks for this tutorial that got me started.

There is actually no need to prevent the Yoga 920 from going to sleep, as it goes to sleep and wakes up without an issue. However, if VoodooI2C.kext (ver. 2.2) is loaded (regardless of whether it's injected or put into /Library/Extensions), sleep is broken.

The second problem I'm having is that audio over USB-C (LG 38UC99) ins't working reliably.

I actually don’t have this laptop anymore. I also never tried to use any sort of audio device through the USBC port so I can’t offer any insight there.

I managed to set up my Yoga 910 almost perfect. Only the position and the fingerprint sensor are not working, other than that everything is just as smooth as on my Air. That is a perfect laptop as a Hackintosh, clearly never had any better user experience on a hack.

So you're saying that also sleep is working faultlessly?

Absolutely! Just like real Mac.
Thank you for answering. Sleep works for me on my 920 as well as long as I don't use VoodooI2C. Do you also use VoodooI2C and, if so, which version?
