Meta launched Muse earlier this month as its first consumer AI agent. The company said on Friday that the same tool is now on Mac. It had already reached iOS and Android. The US remains the current market.
Muse is built to finish multi-step tasks, not only answer questions. It runs inside a dedicated virtual machine called Muse Secure VM. From there it can work across everyday apps, if the user allows it. Meta says the agent learns from conversation and can continue work from earlier chats.
A Meta post on X confirmed the macOS app. The desktop version is meant to act on the computer itself. One example is sorting a downloads folder. The agent can also search for a lost file. It can summarise messages, Calendar items, and notes. Those steps follow the permissions the user sets.
On Mac, people can ask Muse to send email, plan travel, or turn a long-term goal into a checklist. It can open a browser and fill forms. Meta also says it can negotiate on a user’s behalf. The same agent can run in the Muse app or through WhatsApp.
The company claims Muse remembers details that matter and can offer suggestions without a new prompt. A person may mention something only once. The agent may still use it later. Users can tell it to forget selected items.
A separate host-side agent called Sentinel works alongside Muse. People control which apps the system may touch. Meta says Muse cannot see passwords or payment methods. Shared credentials go into secure storage. The agent can use them without reading them, including passwords typed in the browser. It is supposed to ask before sensitive steps such as sending mail or making a purchase.
These are Meta’s design claims. Independent testing will show how the Mac app behaves in daily use. Availability outside the US has not been broadly confirmed.
