MacBook Pro overheating

The newer Apple laptops will get hot when being used. It is normal. The laptops contain very powerful CPUs in a very slim case so heat will build up in them. Even just using a web browser can stress the laptop and make it hot depending on what websites you are visiting. Of course you may have an app that is running non-stop and causing the laptop to run hotter than normal. You can run EtreCheck and post the report here using the "Additional Text" icon which looks like a piece of paper. You can also check Activity Monitor to see if an app is using excess CPU resources.

You can always run the Apple Diagnostics to check the fan and temperature sensors are working correctly. Of course Apple's service diagnostics are much more thorough than the diagnostics you can access.

How do you know it is overheating? Macs will shut down before they overheat. Did you have it evaluated at an authorized service center and did they say the computer was overheating?
