Naturally, like most electronic devices, your Mac will become warm when in normal use especially if it has been running for several hours.

Fortunately, there are several practical solutions to resolve Mac overheating problems irrespective of the cause or related symptoms.
Solution 1: Managing Possible Causes of Overheating in Mac
In some situations, the overheating problem may not be related to the hardware or software malfunctioning but just the way you use the device.
Ensure that the Mac ventilations, located at the back of the screen hinges in most models, is free from any blockages, dust or debris.
Avoid using your Mac on soft surfaces such as a bed or any other cushy surface where the ventilation could be blocked.

When your MacBook overheats, the problem could be the charger and not the machine itself.
If the device is connected to the charger, disconnect and shut down the machine.
Give it a few minutes to cool down before restarting and try running it when not charging. If the overheating stops then the charger could be faulty.
First ensure that you are using an original charger and cable to charge your machine, preferably the one you bought with the MacBook.
Examine the charger for physical damage and if need be, replace the charger with the recommended options for your specific model.
Solution 4: Managing Mac’s Activities with Activity Monitor
