Meta says its Muse AI agent can now operate apps on a user’s Mac with permission. At Meta Connect on September 23, the company also previewed a real-time voice avatar and an email address for the agent, and named new shopping and productivity services it plans to connect.
Meta introduced Muse on September 8 as an agent that could work across connected services. The Connect announcements extend it toward direct desktop operation and give people more ways to send it tasks. The changes are at different stages: Meta describes Mac computer use as available now, but gives no release dates for the avatar, agent email address, or every newly named connector.
Mac Control Is the Immediate Change
Muse already had a Mac desktop app. The new capability, according to Meta, is computer use: with the user’s permission, Muse can drive any app on their Mac. Meta also says it can continue working through queued tasks after the user steps away.
That goes beyond finding a file or handling a message through an existing integration. By operating an app, an agent could potentially follow a task through its interface without a dedicated Muse connector for the service. It would also encounter the buttons, forms, documents, and unexpected pop-ups a person would have to navigate. “Can drive any app” describes the access Meta is offering. It does not establish that Muse can complete every task reliably in every app.
There is a timing discrepancy. TechCrunch’s account of the Connect keynote described Mac computer work as something users would soon be able to do. Meta’s written recap says computer use is “now available.” The written statement is the clearest indication of current availability, though neither account establishes how broadly the update has reached Mac users. Meta’s recap also does not explain what happens to a queued task if the Mac locks, sleeps, loses connectivity, or presents an unfamiliar prompt.
For someone deciding whether to delegate work today, direct app operation is the update to look for. The Mac app itself already existed, and the future avatar preview does not indicate whether computer use is enabled in a particular installation.
Desktop Access Raises a Different Permission Question
At launch, Meta described Muse as running in a dedicated cloud-based Muse Secure VM with its own browser. The company said users choose which services to connect and how much access to grant. It also described a separate Sentinel agent that checks activity reaching the internet, an audit trail, and approval requests before sensitive actions such as sending email or making a purchase.
Those safeguards are described by Meta; they have not been independently audited here. The Connect recap says Mac app control requires permission, but does not explain in comparable detail how the previously described VM protections apply when Muse operates software on the user’s own computer. A browser in an isolated environment and an agent interacting with local desktop apps raise different access questions. Their controls should not be assumed to work identically.
A Mac app might show material from multiple accounts in one window. A mistaken click could change a document, send something to the wrong place, or trigger an unintended workflow. Content an agent reads may also contain instructions that conflict with the user’s request, a known concern for systems acting on untrusted material. These risks do not establish that Muse will make such an error, but permission to operate an app is no guarantee of correct action.
Users should grant only the access a task needs and review consequential actions. Meta says Muse requests approval for sensitive steps in its original agent workflow. The Connect recap does not provide enough detail to conclude that every Mac-app action is individually reviewed or reversible.
The Voice Avatar Is a Preview, Not a Requirement
Meta showed a version of Muse designed for continuous spoken conversation. The company says users will be able to describe the voice they want, including its pace or accent, while Muse works on tasks in the background. Its separately named Muse Realtime Avatar technology is intended to give those conversations an expressive, interactive visual counterpart.
Meta presented the voice and avatar experience as a coming feature. TechCrunch reported that an avatar was demonstrated at Connect and likewise described it as a future capability. Neither account gives a firm public release date.
An avatar could make a long interaction easier to follow, but its appearance says nothing about whether the agent completes tasks accurately. “Real-time” should not be read as a measured latency claim for every conversation or action. Meta has not supplied independent performance results for the experience in the cited announcement.
The avatar is separate from the Mac update. Users do not need a digital face to use Muse’s proposed ability to move through desktop apps on their behalf.
Muse’s Own Email Address Would Create Another Way In
Muse can already work with email as part of its agent role, according to Meta’s September launch announcement. At Connect, Meta announced that Muse will have its own email address, which people can use to reach the agent and which the agent can use to get things done.
TechCrunch reported that users would be able to add Muse to an email thread or forward it a message to handle. An ordinary conversation could then become the starting point for an agent task, without the user opening the Muse app. Meta’s recap leaves several questions unanswered: who can send instructions to that address, how Muse distinguishes a user request from other text in a thread, and which actions still require approval.
Meta has not given a precise availability date. The forthcoming address is not yet a confirmed active feature, nor does the announcement grant Muse permission to send mail without user oversight. At launch, Meta said Muse asks before sending an email. How those controls will appear in the new email workflow needs clearer documentation.
More Connectors Bring Shopping and Work Closer Together
Meta’s initial Muse launch included connected services and access to the Shopify catalogue. At Connect, the company named a wider set of merchants, including Walmart, Best Buy, Sephora, and Wayfair, alongside Shop Pay and PayPal for payments. It also listed Notion, GitHub, Granola, and Box for work, said Expedia was coming soon for travel, and named Instacart for grocery shopping.
The connections serve different parts of a task. A retail connection might help an agent find a product, while a payment option concerns checkout. GitHub or Notion gives Muse a route into work information. The full list shows the range Meta is pursuing, though it does not mean every partner is available to every user today or that every integration permits the same actions.

1Can Meta Muse Control Apps on a Mac Now?
Meta says Mac computer use is available now and that Muse can drive any app on a user’s Mac with permission. It also says Muse can continue queued work while the user steps away. TechCrunch described the capability as coming soon in its keynote coverage. The announcements do not establish how broadly the update has rolled out or how reliably it handles every app.
