Does the Magic mouse work with the MacBook Pro 13" early 2016?

The Apple Magic Mouse even works file on circa 2011 Mac Mini with High Sierra macOS 10.13.6.

As mentioned by previous posting the builtin Trackpad wis excellent.

Ah - the old batteries need charging

Welcome and Thank you too.

Do come back to the ASC Forums, in the future, if / or when additional question may arise

Yes, it does.

May I ask why? The laptop's trackpad is excellent...
