MacBook Pro CPU overheats

Try resetting your SMC.

Resetting the SMC of an Intel-based portable Mac with a battery you should not remove on your own

Note: This will not delete any data.

The SMC is responsible for controlling various system functions. None of your data will be deleted by resetting the SMC.

Shut down the computer by going to Apple () > Shut Down…

Select Shut Down or allow the computer to shut down automatically.

Plug in the MagSafe power adapter into a power source and then connect it to your Mac if you have not already done so.

On the built-in keyboard, press the (left side) Shift (⇧), Control (⌃), and Option (⌥) keys and the Power Button at the same time.

Release the (left side) Shift (⇧), Control (⌃), and Option (⌥) keys and the Power Button at the same time.

I hope I helped.

Download from the Internet istat pro.

Open Activity Monitor to ALL PROCESSES and set %CPU to display values from high to low.

When your MBP gets hot, post images of both for inspection.

These are from mine:

Ciao.

Sorry to say but no Mac notebook is designed to run game apps for any length of time without the system getting incredibly hot. They just don't have the proper cooling for running them hard the way games tax the hardware. Your question is asked several times a week if not more. The only thing you can try is to use some type of cooling pad to TRY and keep the heat down.

Or buy a computer that is better suited for playing games on.

I have a constantly overheating MacBook Pro issue.

As far as my diagnosis found out, its only the CPU overheating not the GPU.

Unless you have specific temperature data, it is an unknown if there is a problem, and if there is, the extent of the problem.

Ciao.

Well, the CPU gets up to 86 celsius or sometimes even reaching 90. I know its not too hot for damage, but it clocks my CPU down.

I agree that the temperatures for the types of applications you are running are producing temperatures well within acceptable bounds.

Apple Intel processors do have a shutdown provision for excessive temperatures. OSX has provisions to throttle the CPU if the battery is not connected. But I am not aware of any other throttling of the CPU prior to reaching the maximum designed operating parameters.

Rising temperature will create more resistance and have a negative affect on CPU performance, but temperature is taken into account in the design of the CPU. Thus a properly performing CPU should be able to attain and maintain designed speeds prior to thermal shutdown. If you are finding that the CPU in your MBP is failing to do that, it suggests that your CPU may be faulty.

Ciao.

Did my solution help you at all?

If you need anything else, just ask!

If you keep an eye on the battery charge indicator, both on the AC changer end that connect to the system and in the menu bar, you might notice when you are Taxing the system the battery charge percentage goes down and the light on the AC adapter turns to green, if it was charging the battery, or when you stop taxing the system the light turns amber signifying the battery is being charged. That is because the AC adapter can't supply enough power to do both run all the heavily taxed hardware in the system and either charge the battery or keep it charged. When taxing the system it will draw power from both the AC adapter and the battery at the same time.

You can reject my observation that Mac notebooks aren't meant or designed for gaming but that doesn't change the fact they aren't.

Yes this is exactly what I wrote about. Two things can clock down the CPU, one is heat and one is the battery. That right, well I have the battery normally connected and the battery if not really used since I bought it, 53 cycles now.

ase.

I own an early 2011 13' MacBook Pro which worked flawlessly until the new macOS arrived. I tried everything stated about the SMC, even took it for some internal clean-up but the problem persisted, perhaps not to the level some other users indicate (hot case or unexpected shut-downs) however it was constant to listen to the fan going all the way up, sometimes with very common processes such as booting-up or even surfing the web (I won't mention when the laptop was used for some heavy tasks).

I even considered to have it re-checked as perhaps there may be a physical damage anywhere (it's an old machine after all) or to roll-it back to El Capitan, however I decided to give macOS another shot and after updating it yesterday, seems all problems are now gone, read somewhere in google a couple of months ago that macOS was giving a sort of hard time because of this to some users (however never heard it from an official source) and therefore was doubtful, however at least so far, my laptop is working great, even better than a newer desktop PC I also own.

My configuration is as follows:

MacBook Pro 13' early 2011

2.3 GHz Intel Core I5

8GB RAM

Intel HD Graphics 3000 (512 MB)
