I think, the difference between 820 G3 and 840 G3 is only in the size display:

820 - 12.5"

840 - 14"

 

Can you share your System Report from HP 840 G3 with Sonoma? I want to compare with your hardware with me.

Thanks)

I used Samsung SSD 2,5" (model: ST1000LM024)

I made all points from Manual, from forum, step by step.

And when installing, the laptop was overloaded several times, but the installation process did not show off, showing the remaining time.

And then during the load of OS begin showing issues. 

 

Before I tried install Ventura 13.6 on this laptop -  and all was successfully. 

Hardware in the laptop - ok, I'm sure.

Perhaps there is a way to record a log file when loading open core? 
I badly understand how to do Opencore EFI for macOS

Hello!

• Integrated Intel HD Graphics 520
• Non touch 14" LED backlight FHD (1920 x 1080) with camera
• hard drive 2,5" SSD
• 8192MB RAM
• Intel Wireless-AC 3165 802.11 a/b/g/n/ac WiFi and Bluetooth 4.0 combo
• Intel Ethernet I219-V 10/100/1000Mb/s

 

I'm tried EFI from forum: EFI 

I have formatted the drive as macOS Extended Journaled as well as APFS with GUID partition maps.  Laptop have Intel, I've renamed Config-IntelWifi to Config.plist. 
I'm trying to install Sonoma 14.3.1. However, unfortunately I get a lot of issues when loading. And the system freezes.
