Cenno is a macOS app that lets you control your Mac with hand gestures, using the built-in webcam. You can move the cursor, click, scroll, switch Spaces, open Mission Control, change the volume and more without touching the trackpad. ### Is Cenno free? Yes. Cenno is free, with no account and no ads. If you find it useful you can support it through Ko-fi. ### Does Cenno send my camera feed anywhere? No. Cenno runs entirely on your Mac. There is no server, no cloud processing and no data collection, so the video never leaves your computer. ### Which Macs does Cenno support? Cenno needs an Apple Silicon Mac with macOS 12 or later and a webcam. A Windows version is planned. ### Why does macOS block Cenno the first time I open it? Cenno is not signed with an Apple Developer ID yet. Open System Settings, go to Privacy & Security, scroll down and click Open Anyway. You only need to do this once. ### Does Cenno work with my dictation app? Yes. The hang loose gesture toggles dictation in Wispr Flow, Apple Dictation or a custom shortcut, and a thumbs down removes what you just dictated. ## Links - [Website](https://cennoapp.com/) - [Download (GitHub Releases)](https://github.com/sapucaialuann/newMotion/releases/latest) - [Source code](https://github.com/sapucaialuann/newMotion) - [Feedback and feature requests](https://github.com/sapucaialuann/newMotion/issues) - [Support on Ko-fi](https://ko-fi.com/sapucaialuann) - [Luann Sapucaia on LinkedIn](https://linkedin.com/in/sapucaialuann)
