Several users have reported a problem in which MacBook (especially MacBook Pro Retina Display and Macbook Air) is running very hot. This is an important issue because If the temperature in your MacBook gets too hot, it may damage some components in your laptop.
Please note that the bottom surface and some areas between the keyboard and screen can get warm after extended periods of use. This is normal. But if you think that your computer is getting too hot, you may try the followings:
- The problem may be that you use the MacBook on an uneven or soft surface (e.g. pillow or blanket). Do not use your computer in this way as soft surface may block the airflow vents. Place your MacBook on solid, flat surfaces.
- Ensure that you are running the latest system software.
- Some apps may cause affect the heat level of your computer because of excessive CPU usage. To check this, launch Activity Monitor (Applications/Utilities). If you see any process taking more than 70% of the CPU, it is considered to be placing a significant load on the system and this may cause your Mac running hot. You may want to quit the application to stop it from using the CPU.
