Microphone Access (Microphone) is a macOS privacy permission. Microphone access allows an app to capture audio through your Mac's built-in microphone or any connected external microphone. Unlike the camera, there is no hardware indicator when the microphone is active, making unauthorized recording harder to detect. Common apps that request this permission include Zoom, Slack, Google Chrome, Discord, GarageBand. Risk level: danger. To check which apps have this permission, open System Settings, go to Privacy & Security, and select Microphone. CoreLock identifies every app and background process with microphone permission, including helper tools and launch daemons that don't show up in your Dock. It flags suspicious combinations — like a utility app that also has microphone access — and tracks when permissions change over time.

Click the Apple menu and select System Settings.
Click Privacy & Security in the sidebar.
Click Microphone in the privacy list. You'll see every app that has requested microphone access.
Review each app in the list. Pay special attention to apps you don't remember granting access to, or apps that shouldn't need a microphone (like a calculator or file manager).
Navigate to the Microphone permission list.
Click the toggle next to any app to revoke its microphone access immediately.
The app may need to be restarted for the change to take effect. Quit it fully (Command+Q) and reopen it.

Unlike the camera's green LED, there is no hardware indicator for the microphone. Starting with macOS Monterey, an orange dot appears in the menu bar when an app is using the microphone, but this is a software indicator and could theoretically be bypassed by sophisticated malware. CoreLock monitors microphone access at the system level for an additional layer of visibility.
Yes. Once an app has microphone permission, it can record audio even when it's not the active window. This is by design for apps like voice recorders or meeting tools, but it means a compromised app could eavesdrop silently. Check System Settings regularly or use CoreLock to audit which apps hold this permission.
If you use web-based video calling (Google Meet, Zoom Web), your browser needs microphone access at the system level. Rather than revoking it entirely, manage per-site microphone permissions within your browser's settings for more granular control.
CoreLock scans every app on your Mac and shows you exactly which permissions each one has. Find hidden access in under 60 seconds.
