I’m guessing here but given the target of macOS this is done to prevent the GPU from being used. Many apps on macOS can do their drawing on the CPU or via the onboard Intel graphics. Metal presumably would force the GPU on, which would impact battery life.

Except that is not how it works. Metal absolutely works with the integrated GPU.

He wasn't saying metal can render via the cpu, he was saying that macos apps in general can choose whether to use cpu or gpu rendering.
