With the Steam Deck releasing towards the end of the year, and the ability to install any OS, could it possibly support MacOS? It has Ryzen CPU and a AMD RDNA 2 GPU

The Steam Deck is essentially a portable computer. You can no doubt about it, get OpenCore working with it. I thought it would be cool as hell, to have a Windows desktop gaming computer, a Mac Pro, and the portability of a Nintendo switch all in one tiny ass device... for just $400. (it can also connect to external displays, and you can use a USB HUB, mouse and keyboard on it as well, just like any other computer)

The ryzen CPU wouldn’t be an issue but the AMD RDNA 2 gpu, is the same one used in the PS5, and the Xbox Series X. Not sure if MacOS would support that or not...
