Unity does not use a high-performance GPU on Mac (macOS 10.15.1 / MBP 16")

Hi,

I just bought a new laptop (MacBook Pro 16" 2019) and trying Unity. However, when running unity 2019.2.f4, it uses an integrated gpu instead of a high-performance one, which is Radeon 5500m. How can I make Unity to use high-performance GPU?

My GPU switching is enabled in the energy setting, but if I remember it correctly, Unity switches to the high-performance GPU even when the automatic switching is on when I was working on my previous machine (MBP 15").

I investigated further and updated this issue here:
