How to Check CPU Temperature with Activity Monitor

All Macs come with the Activity Monitor built into macOS, providing a quick way to get current CPU temperature readings. To check CPU temp Mac, follow these steps:

  1. Open Activity Monitor – You can find it using Spotlight or in /Applications/Utilities.
    CPU temperature macOS
  2. Navigate to the CPU tab.
  3. Check the Temperature column on the right. This shows the current CPU temperature in degrees Celsius or Fahrenheit.

The CPU temperature will fluctuate frequently, especially on laptops, so expect variation. Look for sustained high temperatures over 90°C / 194°F under load or spikes over 100°C / 212°F, which may indicate cooling issues.

Activity Monitor is handy for a quick current reading but doesn’t log history. For that, we need to turn to third-party tools.
