Allow Permission

KeyCastr requires your permission to receive events from macOS in order to broadcast your keystrokes and mouse clicks.

On newer versions of macOS (10.15+) there is an Input Monitoring menu under Security & Privacy within the System Preferences app, and KeyCastr will appear there automatically the first time you run it. Simply unlock this menu and check the box next to KeyCastr to enable it.

On older versions of macOS, or if for some reason the app doesn't appear under the Input Monitoring menu (or if you want to pre-enable it) then you may manually add it to the list of apps in the Accessibility menu.

To add KeyCastr to the list click the + button and select KeyCastr from the file system, or drag it in using Finder.

If KeyCastr is already in the list you can remove it with the − button and add it again in order to be certain that the right copy of the application is specified.
