Meta’s Muse Hits Mac, Letting the AI Take Actions on Your Computer

Meta has launched a Mac version of its Muse personal AI agent, giving the system access to files and applications on a computer and allowing it to carry out tasks rather than simply respond to questions.

The new Mac app can interact with files, Messages, Calendar, Notes and Mail, according to Meta and reporting on the launch. This allows Muse to combine information from different applications and complete multi-step tasks directly on a user's computer.

For example, an AI agent could potentially gather information from messages and email, check a calendar appointment and use files stored on the Mac to complete a task. That moves Muse closer to the broader concept of “agentic” AI, where software is designed to take actions on behalf of users instead of waiting for instructions at every step.

Meta introduced Muse earlier this month across iOS, Android, the web and WhatsApp. The company describes it as a personal AI agent powered by Muse Spark, a model designed for real-world agentic tasks. Meta says Muse can handle activities such as sending emails, filling out forms and booking travel, with the agent able to continue working in the background when tasks require more time.

The Mac release also puts greater emphasis on permissions and user approval. Meta says computer access is opt-in, meaning users decide what information and applications Muse can access. The company says the agent asks for approval before sensitive actions, including sending emails or making purchases, and provides an audit trail of actions it has taken or plans to take.

Meta has built Muse around a dedicated virtual machine in the cloud, where the agent and connected data are isolated from other users. The company says a separate security system, called Sentinel, controls whether Muse can access the internet and requests permission when necessary.

Muse's arrival on Mac comes as technology companies increasingly compete to build AI agents capable of operating across applications and completing tasks independently. Other major AI developers are also pursuing systems that can interact with software and services on users' behalf.

For Meta, bringing Muse to the Mac represents another step toward turning AI from a conversational tool into an assistant capable of performing everyday computer work. The expansion also raises new questions around privacy, permissions and how much control users are willing to give AI systems over their digital lives.
