CPU: Intel Core i3-7100; Kaby Lake GPU: Intel HD Graphics 630 RAM: 8GB 2133MHz DDR4 Motherboard Model: Gigabyte GA-H270N-WIFI BIOS revision: F8d Motherboard Model Website: https://www.gigabyte.com/Motherboard/GA-H270N-WIFI-rev-10 Audio Codec: Realtek ALC1220 Ethernet Card: Intel Ethernet Dual GbE LAN I219-V (only one of the two ports works, the one beside the USB-C port doesn’t work) Wifi/BT Card: Intel Wireless 8265/ 8275 (comes with the MB) Other installed OSs: Windows 10 20H2 v2, Ubuntu 20.04.2 Guides used: Dortania’s OpenCore Install Guide. What's working: - iGPU with full acceleration. - Sound. - Ethernet - Wifi and bluetooth. (I’m using the stock builtin card that comes with the motherboard) - AirPort, AirDrop - iMessages, Facetime - All USB ports; USB3, USB-C, USB2 What isn’t working: - Sleep - Chime sound at the loading of OpenCore OS picker
I followed the Dortania’s guide to the letter, then checked the USB I made by that guide. Everything went great except when it reaches the recovery setup ‘language choice’ screen, the screen goes black. I found that the SMBIOS is the problem. iMac18,1 caused me troubles. I changed that to MacPro6,1 and the setup goes very smooth. In OpenCore config.plist, in DeviceProperties section, I added this:
After finishing installing Big Sur 11.2.2, I found that I don’t have internet connection. After trying the other port, the internet is on. The motherboard has two ports, only one port works. The one that is beside the USB-C is not working. The kext IntelMausi.kext is used for the ethernet connection Intel Ethernet I219-V.
I only needed to add three kexts files in the Kexts folder. AirportItlwm.kext, IntelBluetoothFirmware.kext and IntelBluetoothInjector.kext
When I put the driver file CrScreenshotDxe.efi in Drivers folder of OpenCore to screenshots of the OS picker, keyboard keys are disabled at the grub menu of Ubuntu. I removed the file and got the grub menu working normally.
I used Hackintool to map my USB ports. Then added SSDT-EC-USBX.aml and SSDT-UIAC.aml in ACPI folder. Also USBPorts.kext. boot args:
Final thought: This is not my first hackintosh, but it could be the best. If anyone here can help to fix sleep and chime sound of OC picker, I’ll be thankful. [link] [comments] |
