A prebuilt Opencore EFI for macOS on the HP Elitebook 840 G3
WARNING! If running Sonoma, ethernet IS required for initial half of setup if you use an internet-based installer. You will need to install Heliport for Wi-Fi. Ventura users can use Wi-Fi with no issues.
Use 1.x releases for Ventura, 2.x releases for Sonoma.
This is a macOS EFI for the HP Elitebook 840 G3, with support for Intel Wi-Fi cards. Ventura and Sonoma compatible.
Follow the "Downloading macOS" section in the Dortania guide to get macOS - https://dortania.github.io/OpenCore-Install-Guide/installer-guide/windows-install.html#downloading-macos
If your EliteBook has an M.2 NVMe SSD, download NVMeFix.kext and add it to your config.plist using ProperTree. I have not included this in the EFI by default has the most common configuration of the 840 G3 has an M.2 SATA SSD.
