Signal Desktop for Mac is fast, simple, secure messaging for the Mac desktop. It now runs independently of your browser, so, if you’re a Firefox or Safari user, you don’t need to install Chrome to send and receive Signal messages on your computer anymore; if you’re a Chrome user, having your browser open will no longer be synonymous with having Signal Desktop open.
Signal Desktop for macOS brings the trusted private messaging experience of Signal to the Mac desktop, with a simplicity that allows you to seamlessly continue conversations back and forth between your mobile device and your macOS. As always, everything is end-to-end encrypted and painstakingly engineered in order to keep your communication safe – allowing you to send high-quality private group, text, picture, and video messages for free.
