  2. Toggle Show in menu bar to OFF

The menu bar icon will disappear, but the app continues to run normally.

Resource Usage

The menu bar monitor is designed to be lightweight:

  • Updates every 2 seconds (not continuously)
  • Minimal CPU overhead (~0.1%)
  • Small memory footprint
  • No impact on battery life

Troubleshooting

  • Check that “Show in menu bar” is enabled in Settings
  • Try toggling the setting off and on
  • Restart the app if needed

Stats seem inaccurate

  • CPU usage is averaged over cores
  • RAM calculation matches Activity Monitor methodology
  • Some system memory is reserved and not shown
  • Use Compact mode for smaller display
  • macOS may hide icons if space is limited
  • Hold Cmd and drag to rearrange menu bar items

Popover won’t open

  • Click directly on the MyMacCleaner text/icon
  • If another popover is open, click elsewhere first
  • Try moving the mouse away and clicking again

Tips

  1. Use Compact Mode if you want minimal screen space usage
  2. Check Memory Pressure - More useful than raw numbers
  3. Quick Scan Access - Use the menu bar for fast scans
  4. Monitor During Tasks - Watch resource usage while running intensive apps
