This is the most common mistake. Sometimes I’ve mistakenly obstructed my laptop’s vents, resulting in the MacBook Pro getting overheated. (I mean, there’s a reason why it throws out hot air.)  

Also, keep cleaning the air vents with a small brush as they tend to get clogged by dust particles. You have no idea how much damage dust can cause!

If the charging cable is damaged, replace it immediately to avoid any further casualty to the internal components. 

3. Use genuine Apple accessories

If you have had something inside your MacBook changed or replaced – a memory upgrade, a fan change, etc., make sure the components you replaced or installed are genuine and are not some rip-off.
