Gigabyte Z490 Aorus Master macOS Big Sur Hackintosh with OpenCore 0.6.4

Hello Hackintosh users, in this article, I will guide you how to prepare the EFI for Gigabyte Z490 Aorus Master Hackintosh with OpenCore 0.6.4. This motherboard supports the latest 10th Generation Intel processor socket LGA 1200. At the end of this post, you can download my EFI folder and then you can use it to install macOS Catalina or macOS Big Sur. This is pretty general and you may still have some hardware not working. You can then start to do some post install troubleshooting if you have issues.

We do not guarantee that this EFI folder will work on your build. Different hardware configuration requires additional settings on OpenCore. Make sure you understand the Hackintosh basic. Please read and learn the official guide at Dortania OpenCore page before jumping into Hackintosh.

Now you can boot the PC from the USB installer and you should see OpenCore picker menu. Select the one with (External) label. You will need to format the hard disk to APFS file system before installing. Follow the installation steps shown on the monitor. It will restart few times until completes.
