Forcibly shut down my Mac while the app is running Background: I want to operate Mac mini with automatic startup and forced termination just by operating the power supply without attaching a mouse keyboard. However, when I restart, the app will start twice apart from the automatic login start setting, so I would like to stop it.

Is it a completion event or a restart event?

I thought the same thing... Is "MTLTexture.replaceRegion" asynchronous or synchronous, or if it is asynchronous, is there a delegate? but... Due to the machine's convenience, I thought I had to wait until the next drawing timing, so I did it with a double buffer.
