Overview of the Problem

When a USB mouse doesn’t work in macOS, it can be a frustrating experience, often leading to impediments in productivity and workflow. This issue occurs when the operating system fails to recognize the mouse, preventing users from utilizing standard pointing functions. This can stem from a variety of causes, including hardware malfunctions, software conflicts, or incorrect settings. Understanding the reasons behind these issues and how to address them can resolve your mouse-related difficulties efficiently.

Key Takeaways

• Ensure the USB mouse is compatible with macOS.
• Check physical connections and USB ports for issues.
