Magic Mouse secondary click depends on both macOS settings and how/where you click the touch-sensitive mouse surface. Start by confirming Secondary click is enabled.
Steps
- Open System Settings > Mouse on current macOS (older releases use System Preferences).
- Enable Secondary click and choose Click Right Side if that is your preference.
- Rest the left finger lightly or lift it while clicking the right side; Magic Mouse can interpret touch positions differently when multiple fingers rest on it.
- Turn the mouse off/on, charge/check battery, and reconnect Bluetooth if clicks are inconsistent.
- Test another user account or another mouse to separate a settings problem from hardware.
How it works
Control-click on the Mac keyboard provides the same contextual-menu function and is useful as a diagnostic workaround. Accessibility or third-party mouse utilities can override normal behavior.
Important considerations
Clean the mouse surface appropriately and update macOS when supported. If physical clicking fails everywhere, settings changes will not repair a mechanical/battery hardware problem.
Practical guidance
If secondary click works with Control-click but not the mouse, the problem is likely the Magic Mouse configuration/touch detection rather than the application. Remove third-party tools such as gesture remappers temporarily when diagnosing. Bluetooth interference can affect tracking/connectivity, but a consistent wrong-side click usually points to settings/touch placement.
Checking the physical click
Magic Mouse has one physical click mechanism beneath its touch surface, so debris, swelling, or mechanical damage can affect both sides. If clicks require unusual force or the mouse rocks because of battery/hardware deformation, stop troubleshooting gestures and arrange service or replacement. Do not pry the mouse open as a routine fix.
