Use official chargers from authorized Apple vendors. Restart your machine, then press and hold the D key while it reboots to launch a hardware scan. The results will be displayed on your screen when the scan is complete. Laptop computers need ventilation to prevent overheating, because their internal components are packed so close together — and MacBooks are no different. Ultra-thin notebooks such as the MacBook Air are particularly sensitive, but MacBook Pro air vents should also be left clear as well.
Built-in fans need cool air to circulate, so blocking the air vents practically guarantees that your MacBook will overheat. Whenever possible, avoid placing your Mac on a soft surface such as a bed, or your lap, as this is likely to smother the vents in the rear screen hinge. Instead, hard and flat surfaces are ideal for maintaining airflow.
Even a brand-new MacBook Pro has a finite amount of computing power. Even low-impact applications can be problematic if enough of them are stacked on top of one another. Over time, dust and other detritus inevitably accumulates within your MacBook, clogging up sensitive hardware components. To clean your computer safely and effectively, remove the bottom panel if possible to access the nuts and bolts of your machine.
Use a can of compressed air to clear away any debris lodged in the ventilation ducts or the fan itself. Then carefully wipe away any other dirt with a lint-free cloth. Digital dross also contributes to overheating, which is yet another reason why using top-of-the-line cleaning software to clean up your MacBook is so important for keeping it in peak condition. Certain Trojans and spyware run high-impact processes without your knowledge, which could explain why your Mac is getting hot for no apparent reason.
If you suspect malware has commandeered your machine, take steps to remove any viruses from your Mac and neutralize ransomware immediately.
Then, install robust security software to keep your MacBook safe and your data secure. Its intuitive toolkit helps you lighten the load by ditching junk files and programs at the click of a button.

Internet of Things. Prolonged body contact can cause discomfort and potentially a burn. The bottom of the MacBook case functions as a cooling surface that transfers heat from inside the computer to the cooler air outside.
The bottom of the case is raised slightly to allow airflow, which keeps the unit within normal operating temperatures. In addition, warm air is vented from the slots in the back of the case.
I have often used my Macbook for long periods of time in the lap editing image and I can assure you the MacBook got extremely hot. I was baffled to say the least! Is this ok? Or should I take it back to the store? Thank you so much JP. Very good and useful information. Love my MacBook Pro and need to make it last. Hi have burned out two times the amd video card on my macbook pro It had overheat and noisy to luckily its withing cooling period so Apple replaced it.
I ran and running just two application one is google gmail and another one youtube 4k test video LG 4k external monitor. After 40 minutes its quite hot in the above touch bar and both the speaker side..
Now I am unable to use the external monitor. I purchased the advertised laptop cooler. It works but only on electricity.
It uses up battery power very quickly! As does the mac running on battery power without the fan on intensive computer programs. I have windows 10 and OSX Mojave running with boo camp. Physical Heat and Humidity of your environment heat here is very bad where I live past two years. I am not an expert user so I really need to do something about this.
I have no tech support and this is my only source of education and fun. Mine MacBook Pro was heating up in 10 minutes of active browse surfing. Not talking about when rendering final cut projects.. Works cool. Thanks, JP, for your article above! Even though I use that app frequently, I shut that crap down right away, and the fans and heat have stopped. I shoot photos semi-professionally, and earlier this year I signed up for the Adobe suite.
Still those fans were going nuts and the heat off the keyboard was alarming. Thought it was Photoshop and Lightroom, but perhaps not. Hopefully this knowledge will help if and when this issue arises again. Interesting what Apple writes about third part fan apps. When i bought my macbook pro smoke came out in less then two weeks after the purchase. It was brand new. Hi I have a MBP that is running very hot even after I put new thermal paste on and cleared out the dust build up in front of the fans.
Now the screen comes up with flickering lines after the chimes and eventually they stop and I get a grey screen. I cant seem to get it into safe mode either any ideas? AdBlock extension for safari was spotted heating my MacBook Pro and draining the battery like crazy. Stopped the extension, et voila! Macbooks have poor design to begin with….. Metal absorbs the heat and just regula web browsing..
I can feel the heat coming through the keyboard , chasis …. It is unacceptable in my opinion. I have a thinkpad ts and the chasis is so good. I feel no heat from the top , a bit on the bottom but macbook is like boiling water comared to my lovely thinkpad , do not get me started on the keyboard.. I do not enoying the web browsing on that computer-macbook that is.
Amazing article!! Solved my problem fast. Via Clean My Mac. I did not know about that feature. It went from degrees to degrees in 3 minutes! Just by quitting Keyboard Maestro. Thank you! Question: Laptop is overheating; no automatic shut down though. So whats causing my laptop to heat. Fan is working fine. My doubt: 1. Malware; 2.
Thermal Paste or 3. Please help me out. I loved this article, thank you! I had a question though regarding stands where the MacBook stays closed. I use a stand I bought off amazon and hook it to 2 external monitors. Do you think this can contribute to it possibly overheating? Do you recommend using these? Or would it be best to keep the MBP open while using it to help the air circulation through the keys. Using a late retina MBP here. Number two runaway apps was a great idea.
My computer immediately turned the fan off and cooled down. I have 17 years in programming, based in 3d.. How you guys can not be aware of how heat damages a system over time, boggles my mind. So; A. GPUs are famous for this. Apple is aware that their bottom line is more important than giving you better cooling, so they overcharge for old and lesser CPUs for mainstream users.
Other components are hastened in aging, causing cracks and material fallout C. Rename this website to : CluelessAboutSoftware. The fans were going non-stop and I was afraid the computer would catch fire. Thank you so much, JP. I turned it off and the fan shut off and the computer was fixed in 10 minutes.
It does tell you how good your directions are , thanks again, Lisa. The minute I use iMovie it would overheat and my screen will fade out to white. Until I placed it on top of an Air Purifier that blasted out cold air and my screen came back on again. I anticipate it will happen again but will now try to use less Apps to prevent it from overheating. I guess find ways to limit overheating, raise it high so there is air coming below, clean the dust, use fans and be weary which Apps uses high CPU.
Apple tech saying heat is not an issue millions of posts online and dedicated videos even 3rd party software made for the heat issue. On the i9 16 inch???. MacBooks as still the most powerful but techs support sales and customer service from apple are trash and they will lie to you just to get you off the phone.. This is just a small note, not a huge deal. It popped up at me mid-scan after downloading and it just felt eerily like a trap yes I got it from the Apple Store and not a third party.
Thank you very much! I was so worried about what was wrong with my MacBook Pro since it is less than a year. I got the culprit — runaway apps and phew -forced quit and all is good now. This is very useful. Cleaned the fan as suggested and did the SMC reset on a machine that was getting uncomfortably hot. Worked a treat. One question though… are there any pieces of hardware on an aged machine that can just be worn out and cause overheating?
I know my question shows my ignorance, but like a motherboard or something of that nature? Can never follow click — bait ads, as those pages are so busy, the fan is very high on within 30 seconds. I use my laptop 8 hours a day to work from home, and have been for the last 5 months straight due to Covid Will this method case damage to my internal components, and is a hour work week too much for my MBP to handle?
Wow… My MacBook Pro has returned to normal. A mess of them in your browser could significantly slow down your Mac and make the fans work harder as it tries to avoid heating up. Many Mac users prefer third-party browsers like Firefox, Opera, and Google Chrome , but these browsers consume way more system resources than Safari.
Some MacBook Pro computers have two graphics cards: a more powerful card and a less powerful one. Naturally, the more powerful card needs more resources and may cause overheating and battery draining. And don't worry, it's completely safe to reset. Note: For the latest MacBook models follow these instructions. How is keeping your MacBook updated related to it overheating?
Well, updating to the newest version of macOS fixes software bugs and helps apps run efficiently. After updating to a new version of macOS, background processes start reindexing the system and databases for Spotlight or Photos. This is a time-consuming and CPU-intensive task, but it needs to happen at some point. Another common problem that causes MacBooks to overheat is counterfeit chargers.
Stick to the original charger that came with your MacBook or, if you need a new one, make sure to get it from an authorized Apple store. You can also check if your charger is certified by Apple here. If the fans on your Mac are still going crazy, you can test them by running a built-in hardware diagnostics tool. For more information, check this article on how to use Apple Diagnostics to fix your Mac's hardware. When you do this, you cover the air vents and stop the fans from cooling down the processor.
So the easiest way to prevent overheating is to use your MacBook on a hard, flat surface, giving it plenty of ventilation. A desk or a table will do far better than your lap.
Viruses might hijack your Mac's resources and use them for crypto mining, attacking other computers, and performing other operations that could cause your MacBook to overheat.
