Are there software settings I should check?
Yes, various software settings can affect how the left click operates on your Mac. First, access the System Preferences by clicking on the Apple menu at the top left corner. Click on “Trackpad” or “Mouse” depending on what you’re using. Check the settings under the “Point & Click” tab for trackpads and ensure that the tap to click option is enabled if you prefer integrated tapping. Adjust sensitivity and tracking speed as needed to suit your preferences.
Additionally, it’s worth checking for accessibility settings, which could interfere with how the input devices respond. Go to System Preferences and select “Accessibility.” In the “Mouse & Trackpad” section, ensure that options like “Ignore built-in trackpad when mouse or wireless trackpad is present” are set correctly. After making any necessary adjustments, test the left click functionality again to see if the issue is resolved.
