Setting up Docker instances to run on an AMD-based macOS Mojave Hackintosh without Hypervisor.framework :: Kittywhisker's Nibbles

One of the biggest gripes I've had with macOS, aside from the inability to run Team Fortress 2 is the inability to use Docker instances without having to resort to using VirtualBox, which for some reason provided degraded performance on my system. After the excitement and disappointment from...

Thanks! I'll check that out if the Z590 doesn't work out.

Works perfectly with absolutely zero issues. Yeah, a compatible GPU is required only.

Awesome - I had read through dortania's guide and didn't see that, this is good news!
And I already have the GPU set up from earlier!


Thank you!

Since you haven't steered me wrong yet.... Any guide you recommend for the Z590? (I had started to run into difficulty figuring out what to use around the ACPI section of the guide I had followed earlier)

Depends on what Z590 hardware you have.

I'll start on the https://elitemacx86.com/threads/gigabyte-z590-vision-g-i5-10400f-sapphire-amd-rx-590-opencore.687/ as it should (hopefully) be pretty similar if not identical.

Thanks!

Looks good. For the new CPU, you need to spoof the CPU ID to boot.

Hey Guys, I have a "random pixel" issue with my RX 6800 XT on macOS 11.6.5 Big Sur.

Two weeks ago this pixel started to appear everywhere.
I made a screen recording of it:

This random pixel appear all over the place in MacOS GUI very random and sometimes a lot and never stopping.
In the screen recording I found a way to reliable reproduce the issue.

I tested the GPU in Windows and it works flawless no random pixel issues in the GUI or Shadow of the Tomb Rider Benchmark;
Shadow of the Tomb Rider Benchmark in MacOS also has no issue with radome pixel at all.

GFXBench on macOS, which runs Metal benchmarks produces a lot of random pixels in the tests.

I had an old disk image dumb lying around from 8 month ago of my macOS. After booting it, the same pixel issue was also present there so I can rule out any update related issue.

I tested also a RX 580, which works without any issues in my macOS.

So I narrow the issue down to something with GPU and macOS/Metal related.

Anyone has advice how to proceed?

This is weird. Provide PR files to check further. Include your Card and macOS details.
