Macbook Pro Hot When Charging
There are a few potential reasons why your MacBook Pro might be running hot when charging. It could be that your charger is faulty and not providing the right amount of power. Or, it could be that there are too many apps running in the background and putting a strain on the system.
According to a long-running thread (10 months at time of writing) over on the Stack Exchange, charging the MacBook Pro using the left-side port causes a lot of CPU use for kernel_tasks, as well as excessive heat. Following poor charging practices and using non-Apple chargers may result in MacBook Pro overheating and resulting in poor performance on the MacBook Pro. If you are using the MacBook Pro specifically for professional purposes, such as editing videos, photos, or using high-end home design software, then it is possible for a small chance of device overheating. Excessive overheating on your MacBook could result in it running very slow, freezing all the time, and not functioning as it should.
Exposing Your MacBook Pro to overheated temperatures could lead to problems with overheating, as well as potentially damaging the MacBook Pros outside hardware. If you are working in direct sunlight or a space that is extremely warm, this may result in your MacBook heating up. Putting your MacBook under direct sunlight can dramatically reduce your machines lifespan, and is hazardous. One of the biggest reasons why you do not want to let your MacBook get too hot is that doing so could damage the hardware that actually allows your computer to function correctly.
There are several reasons your MacBook may get warm, but in reality, it is okay for your Mac to be a little hot when you are running normally. We all like using our Macs in bed, but that warm comforter you have on may be a contributing factor in the MacBook Pro getting warm. Depending on the model, your fans might struggle to keep the MacBook from getting too warm. When a cooling fan becomes worn out or cannot work as it should, your MacBook will often feel warm.
An issue with your Macs SMC may explain why the fan is not working properly for cooling the MacBook Air. When your MacBooks fans are running hot, they are useful for cooling down. If the fan is running hot, and the temperature on your MacBook Air is heating up alarmingly, heres how you can keep the MacBook Air cooler. Fortunately, there are some things you can do to cool a hot MacBook and still enjoy using the MacBook.
A hot MacBook is not only unpleasant to use, it may also decrease the lifespan of the battery, and may also cause damage to other internal components. Well, not really surprising, as my MacBook cannot shed the heat, so it piles up.
Even worse, since fabric basically soaks up the heat, this is going to make your Macbook hotter. Similar to a soft surface, dust and dirt on your Mac–especially on the fan–will also cause it to get warmer.
It is not a good idea to place a MacBook on soft surfaces like these, because air circulation underneath and around your PC will not be adequate. When you place a MacBook or a laptop on a soft surface, that stops air circulation, and your device immediately starts overheating. Soft surfaces such as your lap, a bed, blanket, or even a carpeted area on your floor can feel comforting, but softer surfaces such as your lap also cause your MacBook to get hot.
| Reasons | |
| Poorly-behaving apps | Poorly-behaving apps pushing the CPU too hard can cause it to go hot |
| Blocking the intakes | Blocking the intakes of your Mac can cause it to go hot |
| Fans failing | Another reason can be of fans failing |
| Temperature of the room | Temperature of the room in which you are working can cause the MacBook to go hot |
If your Mac is several years old, the dust inside your enclosure may interfere with your fans and keep them from cooling down properly. Some heavy cases prevent your MacBook from shedding heat as it should, causing the overheating problem.
Like it is supposed to, there is the small chance your MacBooks cooling fan is not working correctly. It may even be that your Macs internal cooling fan is malfunctioning. Worse, the MacBook Air M1 does not even have a fan, making it potentially more susceptible to overheating if you can get your hands on the Apple silicon chips tight enough.

If your MacBooks charging issue is really with its battery, you are going to have to swap that out. When the MacBook charger is overheating, you need to fix the initial failure in order to prevent the damage to the Mac laptop.

Fans draw electricity, so as fans turn on, your Mac loses power faster if it is running on battery power. If you connect your power cord to the incorrect side, the increased heat caused by charging can trigger a temperature probe, which sends fans spinning.
There are many things that could be making the Mac run hot, ranging from poorly-behaving apps pushing the CPU too hard, blocking the intakes, or fans failing, or even the temperature of the room in which you are working. Heating issues are not limited only to older laptops that have been used for years, even recently released Macbook Airs and M1 Macbook Pros have been heating up as users are juggling apps, opening lots of tabs in Google Chrome, or using a laptop without adequate ventilation.
Is it normal for a MacBook to get hot?
The potential for heat generation increases with the number of moving parts a machine has. Although there are several reasons why your MacBook Pro can be heating up, it is really typical for your computer to feel a little warm when it is running normally.
Why does my MacBook Pro charger get so hot?
As full charge draws near, the charging current abruptly decreases. Your adapter “brick” will heat up more than usual if it is laying on a soft surface like furniture, sheets, or carpet since air can’t freely circulate around it. Place it on a flat, firm surface like the MBP.
