Check Cpu Temp On Mac


Mac notebooks comply with all temperature limits that are set in national and international safety standards. Make sure to follow the user guide instructions regarding safety and handling.

Mac notebooks have sensors that detect temperature changes inside your computer. If your Mac notebook has fans, they turn on automatically to cool critical components.

  2. Just so you know, the sensor this uses is the CPU Proximity temperature, which is different from the CPU PECI (overall CPU temperature) and each core's individual temperatures, that are often significantly higher than the CPU Proximity. Macs Fan Control reports CPU Proximity on my Mac as 55ºC, but CPU PECI as 63ºC – Velociround Aug 14 '20.

Fortunately, you can easily keep tabs on your PC or Mac’s CPU temperature by installing a third-party monitoring app. How to check your CPU temperature on a Windows PC.

Here are some tips to manage the operating temperature:

  • Make sure that you’ve installed all Mac software updates and all current firmware updates.
  • Use your Mac notebook where the ambient temperature is between 50° and 95° F (10° and 35° C). Don’t leave your Mac notebook in your car, because temperatures in parked cars can exceed this range. You should also use your Mac notebook where the relative humidity is between 0% and 95% (noncondensing).
  • Use your Mac notebook on a stable work surface that allows for good ventilation. Don’t use your Mac notebook in your bed, on a pillow, or under covers.
  • Don’t put anything over the keyboard.
  • If your Mac notebook has ventilation openings, don't put anything into them.
  • Use only Apple-authorized power adapters. Take steps to avoid overheating the power adapter.

If your Mac notebook gets warm even when it isn’t doing tasks that require intensive calculations, or if it has fans that run for a long time, use Activity Monitor to check CPU activity. Look for malfunctioning processes that can put a significant load on the CPU, and check whether Spotlight is indexing your hard drive. You might also need to reset the System Management Controller (SMC) on your MacBook.

If you use third-party apps that measure the temperature of your notebook computer, it’s important to understand that they don't measure the external case temperature. The case temperature is much lower. Never use third-party apps to diagnose possible hardware issues.

If you have issues with your Mac notebook’s operating temperature, contact Apple. Or visit an Apple Retail Store or Apple Authorized Service Provider.

  • You can check your CPU's temperature on a Mac or PC by downloading a third-party app.
  • If your CPU gets too hot for too long, your computer could shut down or stop working permanently.
  • To monitor your computer's CPU temperature, we recommend HWMonitor for PCs and XRG for Macs.

How to check your CPU temperature on a Mac

  1. For Macs, we recommend the free open-source app XRG. You can find and download the app at

    © Emma Witman/Insider Make sure your Mac meets XRG's required minimum version release and processor before you download. Emma Witman/Insider
  2. Double-click the .ZIP file that's downloaded to unpack it, and the application icon will automatically appear in the same folder you saved the .ZIP file. You might want to move this icon to your 'Applications' folder to find it easily in the future.

  3. Launch the app, granting it permission to open if your Mac prompts you with a warning about third-party downloads.
  4. The XRG app, a slender window with a black background, should appear. You can find temperature statistics for your computer, including the CPU, in the middle portion of the window, right under the fan speed.
