OpenCore EFI folder for the HP EliteBook 850 G3 on OpenCore 0.7.1
Clone and copy to your EFI folder. Don't forget to add your own SMBIOS. (ProperTree is advised) I used SMBIOS of MacBookPro13,3, however; I would advise using MacBookPro13,1 or MacBookPro13,2 since they are using Skylake U processors.
git clone https://github.com/lucasrequile/OCEliteBook850G3
Everything is working as far as I'm aware, including native Intel Bluetooth and WiFi support. I am running on the latest MacOS Big Sur 11.4 at the moment.
