Meta brings Muse to Mac with access to native apps
The assistant can work with files, messages and calendars. Access is opt-in, and Meta says sensitive actions require approval.

Muse’s desktop arrival follows its mobile and web launch earlier in September. Sarah Perez reports for TechCrunch that the Mac app can interact with files, messages, calendar, notes and mail within their native applications.
That gives the assistant a different role from a chat window that merely suggests what to do next. It can act inside the software holding a user’s correspondence and plans, rather than leaving every step to the user.
Permissions become part of the job
Users control access on an opt-in basis. Meta also says Muse will ask for approval before performing sensitive actions. That is a company assurance, not an independent assessment of how reliably the app handles those decisions.
For someone trying Muse, the practical starting point is choosing which parts of their Mac to make accessible. Permission to read or work with personal material is part of using the product, not a separate administrative detail. The expansion brings more scope for useful assistance, alongside more decisions about what an assistant should be allowed to touch.
Mac users can now delegate work inside familiar applications rather than only ask for advice. The access controls determine which personal information Muse can use, making permission choices central to the experience.
