Meta’s personal AI agent, Muse, has moved from your phone onto your computer. Released on September 17, 2026, Muse for Mac lets the agent work directly inside your files, mail, messages, and calendar, rather than sitting in a separate chat window waiting for you to type something. Here is exactly what it does and how to get started.
Quick Answer
- Muse for Mac launched on September 17, 2026, about nine days after Muse first launched on phones
- It can work directly inside your Files, Mail, Messages, Calendar, and Notes
- You control what it can access, and it always asks for approval before doing anything sensitive, like sending an email or making a purchase
- It runs through Meta’s cloud servers, not directly on your Mac, which is an important difference from similar tools
- It is free to download, with a usage limit before you need a paid plan
- You can start a task on your phone and pick it up later on your Mac, or vice versa
What Muse for Mac Actually Does
If you have not used Muse before, the core idea is that it does not just answer questions, it takes action. On Mac, that means it can reach into your actual apps and work with them directly. According to Meta, it can organize a messy downloads folder, find a file you have lost track of, summarize your recent messages and notes, draft replies inside Messages, pull information out of your email threads, and add things to your calendar, all without you manually switching between apps to do it yourself.
If you already know how our Meta Muse guide explains the assistant on phones, this is the same underlying agent, just with direct access to how you actually work on a computer.
How Muse for Mac Is Different From ChatGPT’s Computer Use
This is worth understanding, because the two tools solve a similar problem in different ways. ChatGPT’s Computer Use feature takes over your actual mouse and keyboard, controlling your Mac directly as if it were sitting at your desk. Muse for Mac works differently. It runs through what Meta calls a Secure VM, a private, cloud-based environment, and connects to your native Mac apps from there instead of physically controlling your screen. In practice, this means Muse works more in the background, reaching into specific apps to get things done, rather than visibly taking over your entire display.
How Permissions Work
Meta has built this around a permission system rather than giving Muse blanket access to everything on your computer. You decide what it can see and use, on an opt-in basis, app by app. On top of that, a built-in approval layer, which Meta calls Sentinel, requires you to explicitly approve anything considered sensitive, like sending an email, deleting a file, or making a purchase, before it actually happens. Nothing irreversible happens without you confirming it first.
Using Muse Across Your Devices
One of the more practical features is how Muse carries a task across devices. You can start something on your phone during your commute, check on its progress from your Mac once you sit down at your desk, and even nudge it along through WhatsApp if you think of something new to add. Muse keeps track of the same ongoing task no matter which device you touch it from.
How Much Does Muse for Mac Cost
The Mac app itself is free to download. Like the phone version, Muse runs on a usage limit rather than a flat monthly fee. Once you hit that limit, you can either wait for it to reset or upgrade to a paid subscription if you want to keep using it without pausing.
How to Get Muse for Mac
- Go to Meta’s official Muse website or the Mac App Store
- Download the Muse for Mac app
- Open the app and sign in with your Meta account
- Choose which apps and data you want to give Muse permission to access, such as Files, Mail, Calendar, Notes, or Messages
- Start assigning it a task, and approve any sensitive actions it asks about along the way
Why This Matters
Muse reached the number one spot on the US App Store within just eight days of its original phone launch, ahead of ChatGPT, Gemini, and Claude’s own apps. Bringing that same agent to Mac, with real access to how people actually work on a computer, is Meta’s clearest move yet to compete directly in the growing personal AI agent space, where every major AI company is now racing to offer something similar.
