  2. my HP 840 G3 (i7-6600U CPU, HD 520 iGPU with id 0x1916) laptop is working fine on Monterey 12.3 as MacBookPro13,1. In preparation of the coming Ventura Public Release, I genSMBIOS it to MacBookPo14,1. Since WEG v1.6.0 and above can spoof SKL to KBL from HD520 to HD620 then I have updated all kexts to the latest. It can boot into Monterey after iGPU doing retries 50 times and the dock is not transparent. Youtube can be played. But there is some performance lag on the UI. Attached are the DeviceProperties and NVRAM from config.plist I am new to frame buffer patching. Can someone please help me figure out how to spoof HD520 to HD620?
