[Success] Radeon RX 6800 XT - Big Sur

[TheBloke]

So do we now full access to metal and all the goodies on this version ? Have a Sapphire Nitro+ 6800XT. How stable is this version ?

Yes, fully working OpenCL and Metal. Metal is up to 50% faster in GeekBench than OpenCL, a much bigger discrepancy than I've seen on my previous GPUs.

I've been using 11.4 on my main machine for 24 hours and no problems noticed so far. Some people are reporting USB problems, so make sure you have a proper USB Map. And I just learned from someone with an I225-V NIC that they're getting KPs as soon as they plug in an ethernet cable.

Best option for any new macOS release on a Hack - especially a beta that's only been out a couple of days - is to do the upgrade first on a secondary SSD/HDD, or at least to make a bootable backup of your working install before updating the main drive. So you can go back if it becomes unusable.

That said, plenty of people are using 11.4 with no problems so chances are it'll be OK for you too.

The only problem I have is the size of the mouse cursor when using HiDPI modes other than 2:1. It's way too big, but besides that, everything works flawlessly. Also, I just discovered a refreshingly new use case: WoW in 8K. I strongly believe and can not think otherwise, that's what Apple had in mind when they provided the drivers for Big Navi.

What "resolution" & UI "look like" are shown in Sytem info ➧ Display ?

I have a question. My main is windows as I play lots of games. I do have a seprate ssd which I can test for the mac but how should I start doing it ? Windows is already installed on main ssd. is their a way that I can do things without loosing windows and its data and making it a dual boot system.

Yup, dual boot on two SSDs is easy to do.

Follow the Dortania guide for full instructions on installing macOS: https://dortania.github.io/OpenCore-Install-Guide/

As you already have Windows installed and are installing macOS on a second SSD, you can follow the above guide exactly - there's nothing special you need to do. Just be careful when you get into the macOS installer that you format the right SSD! To make things safer, you could even unplug the Windows SSD/NVMe drive before installing macOS, just to be sure you're not wiping the wrong drive. Then plug it back in once macOS is installed.

After following the Install Guide you'll be booting macOS, via the OpenCore bootloader, from a USB stick. After that's done, move on to the Dortania Post Install guide to get everything fully working. One step of that Post Install guide will show you how to copy the OpenCore bootloader and config to your macOS SSD, at which point you won't need the USB to boot any more (though always keep it around as a backup method of booting macOS.)

From that point onwards you will be able to choose to boot either OpenCore (for macOS) or Windows from your BIOS boot picker.

Or, you can choose to boot OpenCore always, and then choose between boot Windows or macOS from the OpenCore picker. However that does mean that, at least by default, OpenCore will change your motherboard name in Windows and you might need to re-activate Windows. Personally I prefer to boot Windows direct from the BIOS boot picker, and only boot macOS from OpenCore.

In no scenario should you lose any Windows data, and in future you'll have an easy dual-boot setup.

Is there an way to disable SAM for macOS (which wont work?) but keep it enabled for Windows?

@oli.mathieu Just like before (meaning with the "old" 5700 XT and 11.2) it's at 6016 x 3384 while looking like 3008 x 1692 @ 60.00Hz on my 4K display. I just discovered that when I zoom in (Accessibility -> Zoom) with Ctrl the mouse cursor turns to the normal size relative to the UI.

Should look like this:

But the cursor has the size of the Full HD HiDPI setting:

System Preferences>Accessibility>Display>Cursor

There is an option to change the size there but by default I think it should be at its smallest.... You can make it even bigger though if you wanna go crazy.

So far no luck on my end on 11.4. My 6900XT is not recognized.
I switched off WEG and moved to MacPro7,1 but no dice.
