macOS does not support touch input.

It would require the biggest UI redesign in the history of the company to ensure every input control is at least a centimetre away from anything else.

And would require every Mac developer to absorb the cost for major updates to their apps as well.

This would almost certainly be an iPad.

Obviously Apple knows how to do touch input.

And it would be possible to update macOS to enable basic touch input for unmodified apps if they wanted to.
