MailHub is an email management plugin for Apple Mail that automates filing, deletion and other actions on incoming and outgoing messages. It allows users to batch-process emails by contact or thread, create new mailboxes during composition, set action reminders, and streamline inbox maintenance without leaving Mail. The installer helper is a background daemon component that was bundled with MailHub to manage plugin installation and updates on Intel-based Macs running macOS Sierra through Catalina.</description> <parameter name="recommendation">This is a helper daemon — a background component of MailHub rather than a standalone application. Dervish Software appears to have discontinued active development and support for MailHub after the Catalina era (around 2019–2020), as evidenced by the absence of any recent updates and community reports of incompatibility with Big Sur and newer macOS versions. There is no native Apple Silicon build of MailHub, and no sign that one is in development. The installer helper itself will stop working when Apple removes Rosetta 2 in macOS 28 (late 2027), taking the entire MailHub plugin with it. If you depend on MailHub's email-management features, start evaluating alternatives now — the built-in Smart Mailboxes and Rules in Apple Mail cover many common workflows, and third-party tools like Mail Act-On (if still maintained) or Apple's own Mail filtering rules may replace your current MailHub functionality. Contact Dervish Software directly to confirm whether a native Apple Silicon build is planned; if not, plan your migration away from MailHub before the 2027 deadline.
