in plain english

Pronto is a small Mac application that lives in your menu bar and lets you turn your La Marzocco espresso machine on or off from your computer. Instead of walking over to the machine or opening a separate app on your phone, you click a coffee-cup icon at the top of your screen and toggle the power. It works with the Linea Micra, Linea Mini, and GS3 models. After installing Pronto, you sign in with the same email and password you already use for the official La Marzocco app. Your credentials are stored securely in your Mac's Keychain and are only sent to La Marzocco's servers to control your machine. Your Mac needs an internet connection but does not need to be on the same Wi-Fi network as the espresso machine, because Pronto communicates through La Marzocco's online service rather than talking to the machine directly. Beyond simple on and off controls, Pronto lets you pick which machine to control if you own more than one. You can set the brew boiler's target temperature within the range the machine allows. You can also turn the steam boiler on or off, which is handy if you are only pulling espresso shots and do not need steam. On machines that support it, such as the Linea Micra and Mini R, you can set the steam level to one of three positions. The menu-bar icon changes appearance to show whether the machine is currently on. Installing Pronto is straightforward. You can install it through Homebrew with a single command, or download a zip file from the project's GitHub releases page and drag the app into your Applications folder. The app is signed with an Apple Developer ID and notarized by Apple, so it opens without security warnings. Pronto requires macOS 14 or newer. The developer has tested Pronto end to end on a Linea Micra paired with a Pico grinder. The Linea Mini and GS3 should also work but have not been verified on real hardware yet. The project includes a developer guide and a release guide for anyone who wants to build from source or contribute. Pronto is an unofficial app with no affiliation to La Marzocco.
