New! – Dark Mode for MacOS
Dark Mode for macOS
Postbox 6.1.3 supports macOS Mojave and introduces a beautiful new Dark Mode theme! Postbox automatically adapts to your Light and Dark Mode preferences.
Easily Switch from Dark to Light
Easily switch between themes using our new "Theme" button to the Postbox toolbar. We've also brought Dark Mode to previous versions of macOS, starting with El Capitan 10.11 and later. (Windows Dark Mode will be available in late 2018.)
