[SUCCESS] Gigabyte Designare Z390 (Thunderbolt 3) + i7-9700K + AMD RX 580

[ummario]

Changing the resolution solved the inverted colours. But computer is unusable. It lags a lot. Opening a .HEIC picture sent form my iPhone freezes the computer for a few long seconds and sometimes even restarts finder. Also notices that can't open Final Cut Pro. Please see picture bellow.

I'm not sure about the cable, but I think when I bought it was suppose to be 1.4.

I'll test further on HDMI, and also will boot on windows again to see if the card has a problem.

Thanks

EDIT: Something seems to be wrong with my igpu settings...

EDIT 2:

The Graphics Card should't be listed on PCI?

if you add it in your config,plist it will show up

But is merely cosmetic correct? I mean it won't solve my lag and freeze problems with RX6900 right?

completely cosmetic, has no relevance what so ever

hackintool can generate a full list of all your devices if you want it to

Thanks... still wondering why this happens with RX6900. My Vega 64 works fine....

maybe @CaseySJ could take a look at your zipped OC folder

 

[ummario]

Can you please do it @CaseySJ? Attached you can find my zipped EFi folder. I removed serial number from config.plist

Thank you so much in advance!

Hi @CaseySJ do you mind to take a look into my EFI folder? My Mackintosh is really unusable using this RX 6900 XT. I'm about to return the graphics card, but before I do it, would like to understand if everything is ok with my settings.

Is really behaving weird... apart form the freezes and lags, I can't even open some webpages on Safari. (I have to disable Java in order to open.)

Also tried a clean install yesterday on a second M.2 disk and happens the same. So I really don't understand if this is a defective card (apparently is working fine on Windows) or some settings are wrong on my EFI folder.

Thanks and sorry for this.

Please try OpenCore 0.7.5 to see whether Bluetooth comes back.

@CaseySJ OpenCore 0.7.5 allows Bluetooth, awesome!

QUESTION:
The computer does not STAY asleep. I don't know the amount of time it sleeps - but it has been alseep for over an hour in testing. I will put it to sleep before bed but the next morning, the computer is running (displays are off). It will turn the displays on if I click/move mouse.

Everything is off in energy saver except "put hard disks to sleep when possible"

EDIT: Attached Sleep Log

Hi @ummario,

Apologies for the late reply. Alder Lake is consuming all my attention at the moment.

Anyway, some things to check from hardware point of view first:

• What is the power rating on your PSU?
• How many PCIe cards are installed?
• Have you considered connecting power cable to 2x2 PEG power adapter near the SATA ports? This will provide more power to PCIe slots.

The other issue is this:
