[SUCCESS] GB Z490M / 10.5.7 / i7 10700K / 5700XT / OpenCore

[nazrm]

Update November 2020: Now running 11.0 with this config. Not going to update this post any more.

I recently updated my hardware and also went from Clover to OpenCore in the process - this was not a fresh installation. There are other successful builds on Z490M, but perhaps this is useful to some! I have been running it a few weeks and haven't had any issues.

Attached my complete EFI-folder and the config.plist separately

• GPU: agdpmod=pikera for the 5700
• Filevault 2 is turned on
• IGPU in headless mode

nice guide, and thanks for posting. what exactly you mean by "IGPU in headless mode"?

 

[oreoapple]

headless mode means igpu will not drive a display but will be used for functions like video decoding(Intel quicksync), Sidecar functions etc.

Not tested sleep propertly, will report back! The board doesn't have a wifi module so no go there. I'll post some pictures in a couple of days. Preliminary build pix below:

I have a similar built but with GA-Z490M UD and having big issues running certain apps. I used your config as a baseline and done modifications as it seems quite similar. No issues installing or with stability. Just that about 50% of apps are crashing on launch

Half of installed apps crashing on launch - 10.5.5 GA-Z490M UD 10700K OC 0.59

Hi all After spending the last 2 days troubleshooting this, I decided to post what I've done and ask for help since there are many new and unknowns for me with this built. I have a fair amount of experience with hackintoshes and clover but none with OC. Components: Mobo: Gigabyte Z490M UD RAM...

Main differences with your system is that i'm using onboard Gpu for now over display port (will plug the rx580 later when working) and use nvme disk (I've also tested on a mechanicanl disk to eliminate issues with the nvme)

I've been troubleshooting this for 4th day now and it started driving me a bit nuts. Any thoughts or ideas would be greatly appreciated!

Saw you got it sorted by adding the other GPU. Never tried my iGPU as a display-out so not sure what could be the problem there.

Hi - Is SSDT-EC necessary for this build?

 

[nazrm]

Can you Provide any Guide. M bit New for Open Core and Want to go ahead with exactly Same System. Will Purchase i7 10700k+Z490M Gaming Board within 1 week.

Hi! I am sure you can just use a general build walkthrough with the EFI provided here. I didn't do a clean reinstall so I didn't follow a guide. Check this one tho: https://dortania.github.io/OpenCore-Install-Guide/

Hi - Is SSDT-EC necessary for this build?

Right now I run without having mapped USB and haven't had any issues (using 5 of the onboard USB ports), but I don't think everything relating to USB is working as it is supposed to, so I will do my own USB mapping sometime. This is the guide I'll follow: https://dortania.github.io/OpenCore-Post-Install/usb/

Will post updates when I get around to it!

I'd very much appreciate your USBMap.kext file once you've created it.
