Since you've already tried some basic troubleshooting steps like restarting your computer, reconnecting the mouse, and checking the system settings, let's dig a bit deeper. Sometimes, issues like this can be caused by a software glitch or a misconfiguration. Here's what you can try:
1. Reset the mouse preferences: Go to "System Preferences" on your Mac and click on "Mouse." Then, click the "Reset..." button to reset the mouse preferences to their default settings. This may resolve any software-related issues.
2. Clean the mouse sensor: Over time, dust and debris can accumulate on the sensor of your Magic Mouse, which may affect its performance. Use a clean, lint-free cloth to gently wipe the sensor area on the bottom of the mouse. Ensure that there is no obstruction that could interfere with the click functionality.
If the above steps don't solve the problem, it's possible that there may be a hardware issue with your older Magic Mouse. In that case, I recommend considering an upgrade to a newer Magic Mouse model, as you mentioned you were having trouble with it. The newer models offer improved features and compatibility.
