I have a Mac Mini hooked up to my TV. We never use anything mode of the TV. (Then again, I have zero streaming services, so perhaps I am not who this article is for.)
So no remote. I get up, hit the spacebar to pause/play. The audio is into a multi-channel receiver though so audio has mute/volume controls on a remote.
I get that people would rather have a remote but I personally actually don't like remotes at all. My TV is basically a screen only.
As far as I know there are no remotes that work with MacOS.
