If single clicks register as double clicks, or clicks don’t register on your M1 Wireless Mouse, try these steps:

• Go to System Settings > Accessibility > Pointer Control and adjust the “Double-click speed” slider toward Slow if single clicks register as doubles.
• Check System Settings > Mouse and verify your tracking and click settings.
• Test in a different user account on your Mac to rule out a software conflict.

If clicks still misbehave after these steps, submit a support request.
