    Hardware: HP ProDesk 600 G3 DM CPU: Intel Core i5-7500T GPU: Intel HD Graphics 630 RAM: Samsung M471A1K43BB1-CRC Motherboard: Intel Kaby Lake - Q270 chipset Audio Codec: Conexant Cx20632 Ethernet Card: Intel Ethernet Connection (5) I219-LM Wifi/BT Card: Intel Dual Band Wireless-AC 8265 What guide/tool followed: What part I got an issue with: Stuck booting "macOS Installer" from OpenCore USB. Picture: What files/config I am using: Extra Info: So the macOS Installer is refusing to boot and I'm unsure what's causing the problem. Please see the screenshot linked above. I tried swapping/deleting some Kexts to see if anything changed but the boot keeps hanging on "apfs_module_start...". I've created my own SSDT's with SSDTTime and also tried the pre-build SSDT-EC-USBX instead of my own SSDT-EC and the pre-build SSDT-USBX. Also after every Kexts and SSDT swap I ran ProperTree to update the config.plist with using the OC Snapshot feature. I also added "npci=0x2000" to my boot args because in the HP BIOS there is no option for Above4G as mentioned here: The HP BIOS is on version "HP P22 Ver. 02.38, 21/04/2021" which is the latest version as of writing. I also changed as many BIOS options possible as listed on the Kaby Lake page of OpenCore. Any help would be highly appreciated as I spend the entire day on this project only running into it not booting.
