    Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

    I can confirm the update to macOS Big Sur 11.3 went flawlessly using the latest EFI bundle.

    Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

    I tried out these voltage settings suggested in the guide and it crashes my system in Windows. Setting the Calibration from Low to Medium keeps the system stable, but I still get self-test errors in Prime95. I have a 10850K and this system really annoys me in Windows. I do not understand how...

    Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

    Thanks a lot, CaseySJ! This did the trick! By the way, I have just installed a new copy of macOS 10.15.7 Catalina. The system is less glitchy overall than Big Sur with the 5700 XT. At boot, however, my screen often does not get detected. However, it is not such a fatal black screen as before...

    Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

    @CaseySJ Is there a new version for the "SSDT-GPRW.aml" : "Disable wake from USB/Bluetooth; wake only with power button" ? I activated the one from the OC161 bundle in the OpenCore config, but USB keypresses still wake the system, unfortunately. Would be very cool! I only had it working on the...

    Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

    I installed the Public Beta! It is not my fault when Apple's public beta updater offers me updates from a different update channel! I have read online that it happens somehow and that people get confused. It certainly has never happened to me before, but on Big Sur it did. I am not kidding you...

    Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

    Do not get the 10900 non-K! You should be able to find a 10850K in stock for around $400. It is nearly identical to the 10900K. But the non-K will be slower. EDIT : Benchmarks here :

    Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

    Alright, I have now installed the Z490 Vision D into my computer. However, I still get black screen when I boot into Catalina 10.15.6 installer... Prepared a USB stick according to the instructions in the thread. So, blackscreen issue is not related to motherboard choice. Oddly enough, I am...

    Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

    Yes. I also have a Z490 Vision G and installed a Sapphire Radeon RX 5700 XT Pulse. I am currently troubleshooting these problems with the help of some wonderful people on this forum. However, I have ordered a Vision D motherboard for testing and will report if the situation is motherboard...

    Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

    Hi there! I reset my BOPS and NVRAM. Loaded Optimal Defaults. However, still black screen at least once when I booted. Really strange. WhateverGreen is definitely loaded according to kextstat. So, now I have ordered a Z490 Vision D from Amazon for testing purposes and will report once it...

    Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

    Very interesting! I will try to reset my NVRAM and go through the steps you've mentioned again. Thank you for sharing your experience with this card. I think I will keep it and hope for the best.

    Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

    It ALWAYS works on BIOS, OpenCore and any other operating system. The "black screen" occurs when macOS is supposed to launch into the graphical user interface. When I connect via Remote Desktop, I cannot see ANY display connected, except the 1280x1024 framebuffer. And oddly enough, when this is...

    Did you ever experience black screen issues during boot? Any troubles? If not, I might send my Vision G back and get a Vision D.

    Do you have the Vision G like me? If yes, can you send me a copy of your EFI folder or config?

    Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

    Availability is different every month or so. Right now, only the MQUPIN Fenvi T919 is available (for 76,99 euro, mind you!) on Amazon. You may order anything from AliExpress, but Amazon only has this limited selection if you prefer instant delivery. Quality of the card I bought now (for only ~60...

    Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

    I just toggled it to the other BIOS, but nothing changed. Took me even longer to successfully boot this time even. I think this is the performance BIOS. I will attempt to remove the agdpmode parameter. Just change around some things. Sleep also does not work, but this was also with the RX 580...

    It does. I left it on default settings. I will toggle it and try again.

    Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

    No difference. It directly started into a black screen. Boot resolution was stretched and awful like in good old 2011 hackintosh days. :lolno: Hm... But thanks a lot for this suggestion.

    Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

    From my experience so far: - Sometimes when I start the system, the screen does not come on - Sometimes when I start the system, the screen has a strange resolution (1280x800 or so) like single-link DVI - Strange artifacts (but not so awful) in transparent list (e.g. in Finder) - Quick look for...

    Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

    OH MY GOODNESS! IT WORKS! :clap: I started completely fresh with the OC 0.6.1 set, applied the changes for Vision G, generated an iMac20,2 model and rom and then needed to do some funky stuff with the plist to be able to add an entry to the "Delete" section under ACPI. (Had to copy an example...
