Mailplane

Mailplane has been discontinued. The developers announced in June 2021 that they stopped selling licenses and would no longer actively develop the app. The core issue was that Google began blocking embedded browsers from its login page, a security measure that made it increasingly difficult to maintain a specialized Gmail wrapper application. Although the developers attempted workarounds, they concluded the situation was unsustainable and decided to stop selling new licenses, focusing instead on other projects. No native Apple Silicon build was ever released — the last public versions remained Intel-only and function only under Rosetta 2. When Apple removes Rosetta 2 in macOS 28 (September 2028), Mailplane will stop launching entirely. If you currently rely on Mailplane, you should plan a migration now. Mimestream is a modern native-Apple-Silicon alternative that consolidates multiple Gmail accounts in a single interface and is actively maintained. The system Mail app, combined with Gmail's IMAP support, is also a straightforward option if you prefer Apple's native client. For users with complex workflows or needing third-party integrations, Gmail's web interface in your browser remains fully functional and will continue to work natively on any Mac regardless of architecture.
