Objective:
Explains how to use Activity Monitor to track system performance and troubleshoot issues on macOS.

Steps:

  1. Open Activity Monitor:

    • Go to Applications > Utilities > Activity Monitor.

  2. Monitor CPU Usage:

    • Select the CPU tab to view how much processing power each app or process is using. Sort by % CPU to identify resource-heavy applications.

  3. Check Memory Usage:

    • In the Memory tab, observe Memory Pressure to see if your system is low on memory. Close high-memory apps if usage is high.

  4. Track Energy Impact:

    • Use the Energy tab to monitor which apps are consuming the most power. This is especially useful for laptop users to optimise battery life.

  5. Review Disk and Network Activity:

    • In the Disk and Network tabs, check read/write speeds and network data usage. Close apps that are excessively using disk or network resources.
