Meta's Mac version of Muse can work with files and supported native apps after a user grants access; its September 2026 documentation describes permission controls in macOS for Full Disk Access, Automation and notifications. The relevant question is not simply whether Muse is “on Mac,” but what information a particular task needs and what the agent is allowed to change.\n\n## Access is a choice, not a single switch\n\nOn a Mac, a request may involve files, forms, or information in Messages, Calendar and Notes. The precise path depends on the permission granted, the app and the task. Mac system settings can revoke access to files or automation. Those interactions can include information from apps and services, even screenshots. Whether those interactions can be used to improve Meta’s models is a separate setting. Permission to read a file is not a blanket reason to let an agent send mail or modify unrelated folders.\n\nMeta also previewed Muse on glasses and a dedicated device at Connect; those announcements do not expand the Mac app's present permissions.\n\n## What each permission changes in practice\n\n**Full Disk Access** is an operating-system permission covering all files on the Mac, even though the agent is meant to use the files and app information you assign to the task. Do not mistake that stated task limit for a macOS folder-level grant. **Automation** can allow actions in local apps, including examples such as sending messages or deleting notes. **Notifications** can report that a background task has finished. These can be revoked separately in System Settings → Privacy & Security. Decide whether a task needs any of them before accepting an OS prompt.\n\nNext consider the flow of information. Task interactions can include information from connected apps and screenshots of your screen. Third-party apps have their own privacy policies, so check what information a task uses across them. The setting that controls whether Muse interactions are used to improve Meta AI models is separate from the Mac's file permission; Meta says it is enabled initially and can be turned off. Its future **Confidential VM** announcement is not a feature available in the Mac app today. These distinctions are useful even if you never choose to grant full-disk access.\n\n## From a local folder to a reviewable result\n\nSay you have a folder of research PDFs, a spreadsheet with last month's results and notes for a team review. The useful outcome isn't “AI accessed my files”; it is a brief whose claims can be checked against those sources, followed by a presentation you can revise with your team. **MuseWork**, a separate product, offers a Mac desktop client for work starting from local files and browser context with your permission. Give the project goal, the relevant files and the audience; inspect the proposed conclusions before turning them into slides.\n\nWhen you leave your desk, MuseWork's mobile app can help you follow the work. The [download options in MuseWork](/en-US/download) show Mac, iPhone and Android separately. Choose the route that fits where the project materials are.\n\n## A bounded experiment for a real work folder\n\nPlace a public sample report, a small spreadsheet and a draft outline in a test folder. Ask for a brief identifying three conflicting figures, with each claim tied to a filename and a proposed slide order. Observe any permission prompt, inspect which apps are invoked, review the result, then revoke permissions you no longer need. This tests the workflow without sending private customer files as a trial. If the goal is a reusable presentation from project documents, MuseWork's Mac desktop app can be assessed on the same criteria: materials in, sources checked, editable deliverable out. The final check is what the app actually accessed and what the team can use.\n\n**[Get MuseWork Desktop for Mac](/desktop)**\n\n[Prefer to begin on the web?
