I'm considering adding a eGPU to my MacMini. I have a 4K monitor and find that the graphics performance to be slow. I'm not talking about gaming but just dragging, scrolling, or maximizing windows. In reading reviews, its not clear if the Mac will use the eGPU for normal UI use. Reviews talk about the need to enable app specific use of the eGPU. Is this relevant for a MacMini or only MacBook Pros with a dedicated GPU. if connected to a eGPU I would only want to use the external GPU and turn off the integrated one. Is this possible and does an eGPU help a MacMini with normal UI performance?
