Why are the scroll controls greyed out or showing the wrong choice?
Start with the symptom you see. A dimmed control, an old highlight, and unchanged scrolling have different causes.

If Scroll direction is dimmed
The app dims Scroll direction when it does not recognize Accessibility permission. It also shows Grant Accessibility access to control scroll direction and Grant Access….
- Open System Settings → Privacy & Security → Accessibility.
- Check that Radar Mouse is enabled for the installed copy you are using.
- If it is missing, click Grant Access… in Radar Mouse and finish the system alert, or add the installed app in the Accessibility pane.
- Return to Radar Mouse and wait a few seconds. The app checks permission repeatedly.
- If it still shows the banner, quit and reopen the installed app, then check again.
A switch that appears enabled in System Settings does not by itself prove the running copy is recognized. Include whether the problem began after replacing, updating, moving, or switching between copies of the app. A different signing identity can require a new permission grant.
Use the setup steps for the system alert. If the built-in trackpad’s direction row is absent rather than dimmed, check Disable trackpad; that row is intentionally hidden when the native option is on and a mouse is detected.
If the app shows a macOS 26.1 warning
On macOS 26.1, the panel can show macOS 26.1 can block this — update to 26.3 or later. The welcome window has a longer version of that advice for a permission switch that will not stick.
This warning is based on the macOS version; it is not a diagnosis of your individual permission failure. Check your version and the actual Accessibility switch. If you are using 26.1 and the switch will not stay on, follow the app’s advice to use 26.3 or later when you can update. If access still fails, send the version and permission symptoms to support.
If Natural or Reverse keeps the old highlight
A direction choice can save and take effect while the panel keeps highlighting the previous segment. Check the actual scroll result before treating the click as a failure.
- Open a document or webpage with room to scroll vertically.
- In the correct device row, click the choice you want once.
- Scroll with that device and compare the result.
- If the direction is correct but the highlight is old, quit and reopen Radar Mouse to rebuild the controls from saved settings.
Closing and reopening the panel alone may retain the same view, so it is not a guaranteed refresh for this symptom. Repeated clicking based only on the old highlight can make diagnosis confusing. If the actual direction also fails to change, use the next checks.
If the result is the opposite of what you expected
Natural leaves macOS’s incoming scrolling unchanged. Reverse flips its vertical direction. Neither choice guarantees an absolute finger or wheel direction regardless of the system preference.
- Note the current Natural scrolling choice in macOS’s mouse or trackpad settings.
- Keep that system choice steady while comparing devices.
- Choose the other Radar Mouse segment for the affected device and check its actual vertical scrolling.
- If you recently changed the system setting, recheck all device choices.
For a clean comparison, quit Radar Mouse and compare the same movement, then reopen it. Choose Natural to preserve that baseline or Reverse to invert it.
If neither choice changes vertical scrolling
- Confirm Radar Mouse is running by checking for its menu bar icon.
- Confirm the affected device has a row in the panel.
- Resolve any Accessibility banner first.
- Check vertical scrolling in a long document or webpage. Horizontal scrolling is not reversed.
- Click Natural, scroll, then click Reverse and scroll with the same device. Judge the movement, not just the selection highlight.
- Quit and reopen the app, then try again.
- If more than one mouse or trackpad is connected, use the device-routing checks.
If the problem occurs only in one app, include that app and version in your report. Also include other mouse or scrolling utilities you use. The enabled segments show that Accessibility is recognized; Radar Mouse does not display a separate confirmation that its scroll-processing connection started successfully.
If the problem starts after reconnecting or waking the Mac, report that trigger and whether relaunching changes it. There is no dedicated reconnect, retry, or wake-status button.
What to include when asking for help
Send these details:
- Your Mac model and exact macOS version.
- The Radar Mouse version or the download you installed, and whether it was recently replaced or updated.
- The affected device’s make and model, connection method, and name shown in the panel.
- Every other connected mouse or trackpad, including receivers.
- Whether macOS grants Radar Mouse Accessibility access and whether the app still shows its banner.
- The Radar Mouse segment you clicked, the segment that stays highlighted, and the actual vertical scroll result.
- Your macOS Natural scrolling choice, other input utilities, and the app in which you tested.
- Whether quitting, reopening, reconnecting, or a recent sleep/wake changes the symptom.
A panel screenshot can help distinguish a hidden row, a dimmed row, and an old highlight. Radar Mouse has no built-in diagnostic export or active/error status screen.
