When an app asks to use your camera, microphone, files, location, or screen, your Mac is giving you a choice. The request does not necessarily mean the app is unsafe. It means the app needs your permission before it can reach that part of your Mac.
The useful question is: does this app need this access for the feature I am trying to use? A video-calling app needs the camera and microphone. A weather app may have a reasonable use for your location. A calculator asking to record your screen deserves more scrutiny.

How do you review app permissions on a Mac?
On a Mac running macOS Tahoe or another recent version of macOS:
- Choose the Apple menu > System Settings.
- Click Privacy & Security in the sidebar.
- Scroll down to the Privacy section.
- Click a category, such as Camera or Microphone, to see which apps have requested access.
- Turn access on or off for each app.
Some changes require your Mac password or Touch ID. You may also need to quit and reopen an app before the new setting takes effect. Turning a permission off is reversible. If an app later needs that access for something you choose to do, you can return to the same screen and turn it back on.
Apple maintains a current overview of the information and hardware you can control, including files, location, camera, microphone, and more.
If your Mac is running an older version of macOS, look in System Preferences > Security & Privacy > Privacy instead. The names are similar, but the layout is different.
What do the main permission categories mean?
- Location Services: Lets an app determine your approximate or precise location.
- Contacts, Calendars, and Reminders: Lets an app read or change information stored in those apps.
- Photos: Controls whether an app can reach your photo library.
- Camera and Microphone: Lets an app capture video or audio.
- Files & Folders: Gives an app access to specific protected locations, such as your Desktop, Documents, or Downloads folder.
- Screen & System Audio Recording: Lets an app see or record what appears on your screen and, when requested, hear system audio.
- Automation: Lets one app control another app. For example, a utility might ask to create an event in Calendar.
- Local Network: Lets an app find or communicate with devices on your home or office network.
Apple explains that modern macOS requires apps to obtain permission before accessing protected files and certain other information. Its platform security guide provides more technical detail about those protections.
Which permissions deserve extra care?
Four categories are especially powerful:
- Full Disk Access can let an app reach protected files and information from other apps.
- Accessibility can let an app control your Mac and interact with other apps.
- Input Monitoring can let an app monitor keyboard, mouse, or trackpad input.
- Screen & System Audio Recording can expose information visible or audible during a recording or screen-sharing session.
These permissions have legitimate uses. Backup software may need Full Disk Access. A window-management utility may need Accessibility. A remote-support or video-meeting app may need screen recording. Grant them when you recognize the app, trust where it came from, and understand why its feature requires the access.
If a request appears unexpectedly, choose Don’t Allow and investigate first. Denying a request is usually safer than approving it out of habit, and you can change the decision later.
Why might a familiar app ask again?
An app may request a new permission after an update, when you use a feature for the first time, or after you reinstall it. Read the wording in the prompt and connect it to what you were doing at that moment.
For example, a browser asking for microphone access immediately after you join a video call makes sense. The same request appearing while you are only reading a web page is a reason to pause and check which site or feature triggered it.
What if an app does not appear in the list?
Apps generally appear in a permission category after they request that access. Open the app and try to use the feature that needs the camera, microphone, location, or other protected information. Your Mac should then display the request or direct you to System Settings.
Avoid following instructions that tell you to grant powerful permissions broadly without explaining why. If an app cannot explain what access it needs, check the developer’s support documentation before changing anything.
Reviewing these settings occasionally is a good way to remove access from apps you no longer use. For another meaningful security improvement, see my guide to passkeys.
