MacBook Pro Overheating [FIXED]?

I think i found a solution and the reason to why the macbooks are overheating. The cause? The CPU is doing all the work.


I watched the cpu and gpu temeratures. My GPU never got too hot(50 c at max?), basically just the heat from everything else heating it up. Meanwhile, my CPU will be up at 80-90 degrees celcius.


System Preferences > Energy Saver > Uncheck Automatic Graphics Switching.


What happens (from my understanding) is that to conserve power, it uses the CPU to do the work of the graphics card, and of course is rediculous when running HD flash vides and such. Unchecking it will force it to always use the GPU. Which, takes a heavy chunk off that CPUs load.


Try it out, see for yourself. All it is is a simple box to check or uncheck if it doesnt do you any good.


For me - It seems to be a lot cooler now that I unchecked that.

MacBook Pro, Mac OS X (10.7), 2.66 GHz i7 (1st gen) 4 GB RAM +SSD

I had a similar issue following an update and was at my wits ends. The processors was clearly overworking and heading.


I fluked a solution that worked for my poor overworked 2.7 GHz quad core i7macbook with 16GB ram...

If you are not storing national or trade secrets on your Macbook, turn OFF FileVault. It seems to thrash the machine as it tries to encrypt everything on your machine.


System Preferences > Security and Privacy > FileVault.


If FileVault is running, click the padlock the bottom, enter your credential and if flick the switch to off... et viola, no more crispy fried prawn balls. 😀

I used to build computers in my youth. Overheating in CPUs becomes more frequent as thermal paste evaporates over time.


Thermal paste is cheap. You squeeze it out of a tube onto the CPU chip, then lock the heat dispersment metal back over the CPU. The fans then blow heat away.


Here is a video of how to do it in a 2011 macbook pro. http://m.youtube.com/watch?v=BqCsZKjwltY


In the meantime, increase the fan speed using the program suggested by previous posters in this thread.


If you let the CPU overheat to over around 65 degrees Celcius, the CPU will shut down torotect itself. After this the computer will often freeze, and even the power button might not respond (to force shut down, disconnect the battery).


Heres a tip: buy a set of tiny screwdrivers so you can open your laptop whenever you want. You will also need a good light an a desk that isnt covered in pizza boxes. Prepare your work area neatly. If you destroy any screw heads, my carpenter friend says you need to lightly hammer a flathead screwdriver into the top of the damaged screw to create a new indent. Dont reuse damaged screws - throw them away - much easier next time.


If you go to a genius bar, they might not think of this solution, so tell them that your CPU's thermal paste may have evaporated. This has cured many of my old IBM Compatibles since 1989.


Macbooks get extremely hot because they do not have a sufficient cooling system. Always angle your macbook a bit so it doesnt make full contact with the desk, and I strongly urge you to get a fan base in summer. Especially if you are taking your laptop o bed with you (I think most people use their computers in bed).


Summer often gets very hot for computers if your building doesn't have airconditioning. Refrigerators from kitchens heat the house, as do some light bulbs. I lived in a van and that gotreally, really hot in summer. The fan speed control program really helps a lot, but its always good to have cold air outside your computer too.


Im quite certain that the most permanent repair for heat creashing computers is the thermal paste I mentioned. Usually less than five bucks.

I started running Fan Control (free from lobotomo.com) and restored Automatic Graphics Switching (Default) for Energy Saver in System Preferences on my MacBook Pro (early 2011). Speed is greatly improved for computer tasks and the overheating stopped. When streaming videos, I put the MacBook on a Laptop/Notebook Cool Pad w/ 3 Fans (<$10) which keeps it nice and cool. The tiles are a great suggestion since the Cool Pad can only be used on a hard surface.

Thank you for the wonderful info!! Your advice re the Activity Monitor showed my HP printer was using 44.7% of the CPU. (Hopefully, I used the correct term!)

I turned the printer off and within 15 minutes my laptop no longer feels even the least bit warm. I now have the Activity Monitor on the Dock and will have the printer turned on only when I need to use it. Last year, I took my laptop to the Genius Bar (have Apple Care) and was told nothing was wrong. Of course not--the printer wasn't connected!! I asked what should I do if my laptop heats up again and was told it was normal to heat up........ So, I am very grateful for YOUR advice!!

I bought a older macbook pro 2008 just for recording music because the drivers for the usb audio interfaces are more stable on osx, but when it comes to hardware Apple really dropped the ball. their laptops have an exhaust port on the back to blow hot air out, but totally overlooked the fact that you need a port on the bottom to bring in fresh cool air to dissipate heat. pretty bad design in general. i bought my macbook on ebay and when it gets here the first thing i will probably do it reapply thermal paste hoping i can get it cool enough to be usable? if not maybe i will opt for a used mac pro desktop?

Hi guys,


I have the same problems as you described. more than that realized we are not alone !


I have recently bought MacBook Pro (15-inch Retina Mid 2014) - Intel Core i7-4870HQ. Gradually, realized the CPUs temperature seem higher that I expected. Exactly the same as the situation you had / have.

this is more than a year when you started this discussion, I wondering if you could give us an update about your MPB. Do you still have it ?

In the near future, is it going to cause a serious failure for my MBP ?

If blocked fan vents and SMC resets don't fix it, it might be software related.

If you go to Console utility you might find the culprit. You might have to disable "system integrity protection" in El Cap. Mine was a location tracker utility that was constantly failing and respawning and overtaxing the system. Look for "launch.apple.xpc.launchd" and what comes after it.

I went to settings and did exactly what you said and saw pictures of where the button is and it is not on my computer. I also went where apple said if you don't see it go to about this mac and system report I did that too but all that happened was this showed up and I see graphics and displays but there is nothing to change on it. Anyone else have a solution or experiencing the same thing?
