  1. How often should I restart my Mac to maintain its performance?

    You should restart your Mac at least once a week to maintain its performance. It allows the system to clear memory, close unnecessary processes, and start fresh, allocating resources more efficiently. You can also restart your Mac whenever you notice a significant decrease in responsiveness.

  2. How does decluttering the desktop improve Mac performance?

    Decluttering the desktop can improve Mac performance by reducing the strain on system resources. Each file, folder, and icon on the desktop requires system resources to render and update, and a cluttered desktop with numerous items can consume significant resources, leading to slower performance.

  3. Why is running a virus scan important for a slow-running Mac?

    Running a virus scan is important for a slow-running Mac because malware or adware infections can significantly impact system performance. Malicious software consumes system resources, runs background processes, and hijacks system resources, leading to a slowdown in overall performance.
