No problem, happy to help!
However, while mobile development is fine, I doubt my mac could handle desktop class games. It would work but it would get really hot and games wont run at 30 fps. If you don’t wanna buy a new mac I recommend a eGPU (bizon box) you can get a graphics card and the box for a pretty good price. The box cost $500 and you cant some high end nvidea gpu to help you run UE better on your mac. While it isn’t portable its something you can use at home or at work to give you a huge performance boost. I think you can get a high end GPU and a 13 inch MacBook for a cheaper price then the 15 inch amd mac. Its well worth it, however portability is something you wont be able to do.
However, its even cheaper just making your own :-p
