How to test a Magic Mouse here
The Magic Mouse has no buttons you can see and no wheel: the whole top is one surface that clicks and reads your finger. The diagram above shows its two click areas and a finger in the middle.
- Click by pressing the upper surface. It counts in the Left row.
- Secondary click on the right side. It counts in the Right row once Secondary click is on in System Settings, Mouse. If it counts as Left, that setting is off.
- Swipe one finger away from you, then back toward you, then to each side. Each of the four swipes should raise a different counter under Scrolling: Up, Down, and either side of Left / right.
- Sweep the mouse around the box for a while to read its polling rate. Apple doesn’t publish one, so the number is there to set against another mouse on the same Mac, not to pass or fail.
Because the surface reports your finger as a stream of tiny scroll steps rather than wheel notches, wheel glitches aren’t counted here. Watch instead for a counter that stays at zero however you swipe, or one that stops rising halfway across the mouse: that part of the surface isn’t reading your finger.
Gestures that stay with macOS
Some Magic Mouse gestures never reach a web page, so they can’t light up here: double-tapping with one finger (Smart zoom), double-tapping with two fingers (Mission Control) and swiping sideways with two fingers between full-screen apps. Apple lists them in System Settings, Mouse, where you can turn each one off. Apple also lists a one-finger swipe left or right to show the previous or next page in apps that support it, so do your sideways swipes inside the test box.
If it stops responding
Check the charge first: Apple’s support pages say the Magic Mouse can’t be used while charging, with the port on its underside. Then check that it shows as connected in System Settings, Bluetooth. A click that registers twice will show up in the double-click detector as a press a few milliseconds after the one before. For a laptop trackpad, use the touchpad test; for an ordinary mouse, the standard mouse tester. The Mac layout of the keyboard tester checks an Apple keyboard.
Every Magic Mouse control and where it shows up
| Control | In the tester above |
|---|---|
| Click (anywhere, or the left side) | Left row |
| Click the right side | Right row, once Secondary click is on |
| Slide one finger up or down | Scrolling panel: Up and Down |
| Slide one finger left or right | Scrolling panel: Left / right |
| Double-tap with one or two fingers | Nothing: macOS handles smart zoom and Mission Control |
| Swipe left or right with two fingers | Nothing: macOS switches between full-screen apps |
