The Magic Mouse has a unique "seamless" design. There are no physical buttons, but the sensor detects the electrical charge of your finger. If the surface is dirty, oily, or scratched, it cannot detect the "swipe" gesture required for scrolling.
Why cleaning matters: A dirty surface confuses the capacitive touch sensor. It might register a click, but it won't register the directional movement of a scroll.
How to clean correctly:
Before diving into system settings, the first and most common cause is often the most overlooked: the physical sensor. magic mouse not scrolling
Because the Magic Mouse uses laser tracking, it is highly sensitive to obstruction. A single human hair, a speck of dust, or a grain of sand stuck to the sensor window on the underside of the mouse can disrupt the tracking ability. However, a specific issue plagues the scrolling function.
The Magic Mouse does not have a mechanical scroll wheel; it relies on the conductivity of your fingers touching the surface. If the surface of the mouse is dirty—covered in skin oils, lotion residue, or grime—the capacitive touch sensors may fail to register the swipe gesture.
The Fix:
If you have tried everything above and it still won’t scroll, you may have a third-party app conflict. Apps like "BetterTouchTool," "Scroll Reverser," or mouse acceleration utilities can sometimes conflict with system updates.
To test this, restart your Mac in Safe Mode:
If the mouse scrolls perfectly in Safe Mode, you have a software conflict. The Magic Mouse has a unique "seamless" design

If the mouse is physically clean but still refuses to budge the page, the issue likely lies within the macOS software architecture. Occasionally, system updates can reset peripherals or introduce bugs that disable scrolling.
The Fix:
If the checkboxes are already correctly set, try toggling the "Scroll direction" off, waiting five seconds, and turning it back on. This forces the operating system to reinitialize the touch recognition protocols.
