Jerry - a silly macos automatic mouse move & click toy

Recently I wanted to look into how to move the mouse around in macos. The end result of my research and experimenting is “Jerry” — a little Swift playground snippet I’ve put up as a gist. When you run Jerry it makes your mouse move around and (left) click at each point. The movement uses easing to make it a little more human-like.

While reading up on the API calls, and refreshing my shallow Swift knowledge I stumbled upon the amazing cliclick tool. That’s where I got the easing code from. To move the mouse around and click I could most likely just have used cliclick instead of writing something myself. But it was fun to brush up on Swift and explore the macos mouse API.
