Mouse Not Responding:
Check if the battery is inserted correctly and has sufficient charge. Replace if necessary.
Ensure the mode switch on the bottom of the mouse is set to the correct connection type (2.4G or BT).

The forward and backward side buttons are not natively supported on Mac OS. This is a system limitation, not a mouse defect.
