Muse for Mac is Meta's free desktop app, launched September 17–18, 2026. Install the right app first and manage permissions properly, and you can use it straight from your computer. The Mac version isn't in the App Store — download the dmg from the official site, muse.ai; it's available only in the United States and Canada, for users 18 and over. Before signing in, set up Muse on your phone, then sign in on your Mac with the same account.
Two steps to install
- Go to the official site, muse.ai, download the dmg installer, and follow the prompts to install it. Don't search for it in the App Store — what you'll find there isn't it.
- Set up Muse on your phone first, then sign in on your Mac with the same account. Phone and computer share the same account and weekly usage allowance. After installing, check the permission settings first and make sure everything is right before you start using it.
Three permission levels, set per app
| App | Off | Read-only | Read and write |
|---|---|---|---|
| Mail, Calendar | Not connected | View only | Can send and edit on your behalf |
| Notes, Messages, Reminders | Not connected | View only | Can write and edit on your behalf |
| Files | Not connected | View only | Requires full disk access |
Actions such as sending an email or placing an order ask for confirmation first — they won't go out silently on your behalf. Start with read-only, and open up read-and-write access once you're comfortable. Permissions can be changed at any time: give read-only today and open it up tomorrow when you need it to send email — there's no need to decide everything at once.
Limits to know
Computer-control features are rolling out gradually through the early access program — they're not all there the moment you install. Phone and computer share the same weekly usage allowance, and Power at $20 per month or Max at $100 per month can raise it. Windows has no native app yet — use the web version. After signing in, confirm the account is the same one as on your phone, so you don't end up with mismatched allowances. And don't install the wrong one: there's another Mac asset-management app also called Muse, from theodorehq, sold for a one-time $29 — a completely different product from Meta's.
