Download MarshEQ 1.0.0v1.0.0 · July 16, 2026 · DMG for macOS 14.4+
First launch: right-click the app and choose Open.
MarshEQ isn't yet notarized by Apple, so macOS shows an "unverified developer" dialog on a normal double-click. Right-click → Open → Open bypasses it once; macOS remembers your choice. Apple charges $99/yr for the checkmark — we're on it, and a notarized update will open without any prompt.
System requirements
