To begin, you will need to download the following files (Note that some of these programs are Windows-only): Dolphin Wii Emulator (Use v4.0.
Please fix this issue since apple wont fix opengl. Even though Project M is designed to be played on a genuine Wii console, it is possible to run Project M on the Dolphin Wii emulator on your Windows, Mac OS X, or Linux computer Downloads.
If anyone who is a dev sees this, we really want vulkan to not crash on boot for basically every wii game. I have a MBP 15' 2019 with Vega 20 graphics and Windows + DirectX 11 gives me incredible performance (Mario kart wii 4k custom textures no frame drops, perfect 60) compared to mac where on OpenGL, something as simple as Wii Play will get a lot of frame drops and stutter on loading not to mention full on crashing with vulkan. To be honest, you are probably better off bootcamping windows until the metal conversion layer gets updated to support all or almost all of vulkan's features. You can try Vulkan but that uses a conversion layer to Metal that hasn't been updated in a while and causes most wii games (at least for me) to crash on boot. The problem with OpenGL on mac is that Apple hasn't updated it in years and that means it doesn't support a lot of features that Dolphin uses to increase performance.
