Open the permission for the app you installed
On current macOS versions, open Apple menu → System Settings → Privacy & Security → Accessibility. Find the clicker in the application list and enable its switch if you want to allow it to control the Mac. macOS may ask you to authenticate the change.
An app may offer a button that opens the relevant settings. Read the name in the permission list before making the change. Accessibility settings for how you interact with the Mac and Privacy & Security permissions for third-party apps serve different purposes.
When the app does not appear or there are several copies
Open the installed clicker once and follow its permission prompt. If the settings pane lets you add an app, choose the copy in Applications that you intend to run. A downloaded installer, a Windows executable and the installed Mac app are different items.
If you see multiple entries, avoid enabling every unknown application. Quit the clicker, confirm the copy you launch, and follow that app’s current support instructions if its permission status remains inconsistent. Do not disable broader macOS protections to make a clicker work.
Test permission independently of speed
After changing permission, reopen the clicker if it asks you to. Configure a slow interval and a small repeat count, then use a harmless test target. A successful controlled test is more informative than a very fast run whose individual actions are difficult to observe.
- Choose a mouse button and a slow interval, such as one second.
- Select a small finite repeat count for the test.
- Bring the intended target into view and position the pointer as required by the app.
- Start the sequence, confirm that clicks reach the target, then test the stop control.
If permission is enabled but clicking still fails
Check focus, pointer position, repeat limits and the selected mouse button. A stop shortcut that works only while the clicker is focused may be a separate shortcut or application problem. A target can also restrict synthetic input; permission alone does not guarantee that every program accepts it.
Record which target fails and whether a simple local target works. Include the macOS version and the test steps when contacting support. Those details are more useful than repeatedly switching unrelated privacy permissions.
Try a controlled session in the Mac app
OP Auto Clicker - Fast Tapper provides interval and repeat controls for setting up a short test. Its free use is limited, and Accessibility permission remains a macOS requirement independent of the purchase status.
Use the Mac App Store link to inspect the app’s current compatibility and support information. Once the permission and stop control work, adjust one setting at a time for your actual task.
