## About
EFI folder for the Gigabyte Z490 Vision G mainboard I've been working on and refining since September 2020. It's based on Dortania's OpenCore Install Guide and analysis of an .ioreg file from a real iMac20,1. I've dumped the system `DSDT`, analyzed it and added missing components and features via `SSDT` Hotpaches from Daliansky's "OC-Little" Repo to get it as close to a real Mac as possible. USB Ports are mapped via `ACPI`, so no USBPort kext is required. I think this is the most sophisticated Z490 Vision G EFI folder available on Github.

This is a *genuine* Z490 Vision G EFI, built from scratch. Unlike most pseudo Z490 Vision G EFIs posted on Forums and Repos, which are either based on generically patched DSDTs by Olarila/MaLDon (stay away from those!) or on SchmockLords EFI for the Z490 Vision D, which contains unnecessary DeviceProperties for Tunderbolt, an I219 Ethernet Controller and on-board WiFi/BT. My EFI Folder doesn't contain any of this junk.

- **SSDT-PORTS**: OS-agnostic USB Port Mapping Table for the Z490 Vision G. No additional USB Port kext or quirks are required. Since the USB ports are mapped via ACPI they will work in *any* macOS. See the "Additional Files" folder for a detailed list of available and mapped ports.

### Patching-in Kepler Drivers

Apple removed Keppler support from macOS Monterey beta 7. So users of NVIDIA GeForce Cards from the Kepler family need to patch them back in post-install using [**Geforce-Kepler-Patcher**](https://github.com/chris1111/Geforce-Kepler-patcher). If you require this patch, you can no longer boot with SIP enabled, so you have to disable it!
