Macs, especially MacBooks can and do get hot. This happens for a variety of reasons and the good news is that the issue is often easy to fix. It is important to fix the issue whenever you can. As your Mac gets hot, you’ll notice that its performance is impaired and this can lead to frustration and a loss in productivity if you use your MacBook for work.
With this in mind, let’s look at MacBook fixes for overheating.
Mac Gets Hot Because Air Vents Are Blocked
A Mac can get hot if the air vents are blocked and with a MacBook, this happens more often than you think. It normally happens when you’re in bed and you put your device on the duvet which is a material that can mould itself to your MacBook and insulate heat. This blocks the vents and everything starts to overheat.
As a general rule put your device on something hard and flat. It won’t mould itself to the MacBook which avoids your Mac getting hot.
Close Browser Tabs
Sounds obvious but the more browser tabs open the more your MacBook is put under stress and could be a reason why your Mac gets hot.
This is compounded by running intensive software that hogs resources. Whenever you run an app or have a browser window open a lot of activity happens behind the scenes. One of which is the generation of cache files. Although these files are designed to make things run faster and truer, somewhat ironically, they can slow down your Mac.
It is good practice to only have apps and browser tabs open that you need. The rest should be closed to stop putting your Mac under stress and to minimise behind the scenes activity.
Are Your Graphics Settings Wrong?
It is possible that your graphic settings are wrong and this is causing your Mac to overheat. The best thing to do in this instance is to enable automatic graphics switching. This is where the integrated GPU, the lesser of the two cards is put into play, leaving the more resource hungry discrete GPU in reserve, and is only called into action when needed.
To do this, go to:
- System Preferences and then Battery. Click Power Adapter or Battery on the left.
- If you have two cards, you’ll be given the option to enable Automatic graphics switching by checking the tick-box. If it isn’t an option your Mac only has one card.
Do an SMC Reset
The System Management Controller (SMC) sometimes develops issue which affects things like fan speed. This can make your Mac get hot. To reset is easy:
- Shutdown your Mac.
- Press and hold Shift, Control, Option, Power buttons for 10 seconds.
- Switch it on.
And that’s it.
Keep Your MacBook Updated
If you’re not running the optimal operating system for your device, you may well experience issues such as overheating. Each new iteration of the operating system brings with it glitch and bug fixes and helps your Mac run faster and smoother.
To check and update, go to:
- System Preferences and then Software Updates.
- If an update is ready for download and install, click Update Now.
Macs are great especially if you keep them cool.
