Meta Muse Launches on Mac With Native App Actions and Permission Controls
Meta launches Muse for Mac, an opt-in AI agent that works across files, Messages, Calendar, Notes and Mail, with approval before all sensitive actions.
Summary
Meta made Muse available on Mac on September 18, 2026, following mobile and web launches earlier in the month that quickly took the assistant to the top of the U.S. App Store charts. Muse can act within native Mac applications, interacting with files, messages, Calendar, Notes and Mail. Access is opt-in, and Meta says Muse requests approval before sensitive actions. Alexandr Wang promoted the Mac release on X on September 17, while Mark Zuckerberg said the team was shipping quickly.
Every major AI company now offers a consumer agent, intensifying a race for market share that could disrupt apps, software as a service businesses and eventually hardware such as the iPhone. Text message based agents have also gained traction. Early breakout Poke exited to Cognition in July, while Instinct is said to be raising additional funding at a $10 billion valuation. Muse and Instinct both introduced voice calling this week as their feature competition accelerates.
