Meta Brings Muse to Mac With AI Agent Access to Mail, Notes, Calendar and Messages

Meta has launched a Mac app for Muse, giving its personal AI agent the ability to work with files and native applications directly on a user’s computer. The desktop version can interact with Messages, Calendar, Notes and Mail, while users control which information and permissions the agent can access.

Meta CEO Mark Zuckerberg announced the Mac release, extending Muse beyond the mobile and web versions introduced earlier this month. The expansion gives the agent a deeper connection to information stored on a Mac and allows it to complete tasks that span multiple applications.

Muse is designed to do more than respond to prompts. On Mac, users can ask the agent to organize folders, complete forms using information contained in their files, or compile an end-of-day summary from emails, messages and notes.

The agent can also work inside supported native apps rather than requiring users to move information manually between an application and an AI chatbot.

Access remains permission-based. Users choose which parts of their Mac Muse can reach and can decide whether to grant Full Disk Access. Those permissions can later be changed through Settings.

Meta is also putting additional controls around actions that could have more significant consequences. Muse will request approval before performing sensitive tasks, including deleting files or sending messages. That distinction gives the agent room to gather information and assist across applications while keeping certain actions behind a confirmation step.

The Mac release follows Muse’s arrival on mobile devices and the web. Zuckerberg highlighted the pace of development around the assistant when announcing the desktop version.

“The team is shipping fast,” Zuckerberg wrote.

Muse has also recently gained voice calling, adding another way for users to interact with the agent as Meta expands its capabilities across platforms.

Bringing Muse to the Mac gives Meta’s assistant a more direct role in everyday computer use. Instead of operating only through a separate chat interface, the agent can now draw from files, communications, schedules and notes already stored on the device, with the scope of that access determined by the user.
