OBS macOS Accessibility Permissions for Hotkeys Explained

This article explains why OBS Studio requires accessibility permissions on macOS to enable global hotkeys. You will learn about the security protocols built into macOS, how background key detection works, and why granting this permission is necessary for controlling your stream while using other applications.

To control your stream or recording using hotkeys while playing a game or using another application, OBS Studio must be able to detect keyboard inputs when it is not the active window. These are known as global hotkeys.

By default, the macOS operating system employs a strict security model designed to protect user privacy and prevent malicious software from acting as a keylogger. This security architecture restricts background applications from monitoring user keystrokes. Without specific user consent, an application can only register keyboard inputs when it is actively focused on the screen.

To bypass this restriction legitimately, OBS Studio utilizes Apple’s Accessibility APIs. These APIs allow authorized applications to observe and interact with the system user interface, including listening for specific keyboard events system-wide. By granting accessibility permissions, you are giving macOS permission to let OBS Studio “listen” for your pre-configured hotkeys even when the app is minimized or running in the background.

Without this permission, your OBS hotkeys (such as starting/stopping streams, switching scenes, or muting your microphone) will only work when the OBS Studio window is the active, front-most application on your desktop, rendering global control impossible.

To enable this feature, navigate to your macOS System Settings, select Privacy & Security, click on Accessibility, and toggle the switch next to OBS.
