Your MacBook Air might be overheating. Does it feel hot to the touch, especially the base?

If so then it might not be getting enough air, and the base might not be able to transfer the heat away.

You should use it on a hard flat surface to avoid overheating issues.

If it is not overheating, then you might need to reset the SMC. More information is available on that here:

https://support.apple.com/en-us/HT201295

Without going through that entire article, the basic steps are:

  1. Shut down your Mac.
  2. Using the built-in keyboard, press Shift-Control-Option on the left side of the keyboard, then press the power button at the same time. Hold these keys and the power button for 10 seconds.
    If you have a MacBook Pro with Touch ID, the Touch ID button is also the power button.
  3. Release all keys.
  4. Press the power button again to turn on your Mac.

Let me know if you have any questions, I am here to help.

I tried that last night but I will try it again.
Mac Support Specialist: David, Mac Support Specialist replied 11 months ago

Ok, thank you.

Those steps reset the SMC, System Management Controller.

The SMC controls the power that goes to the Mac before it can chime.

If resetting it doesn't work, then there is a hardware issue.

A hardware technician can have a look and it might be possible to repair it.

If not then the hard disk should be Ok, so you can ask that it be removed and you can access your data from it.

But if those steps are tried and the Mac still does not chime then it definitely has a hardware problem.

Let me know what happens.

How did that go, did the SMC reset make any difference?

Thanks in advance.

What Customers are Saying:

Hi John, Thank you for your expertise and, more important, for your kindness because they make me, almost, look forward to my next computer problem. After the next problem comes, I'll be delighted to correspond again with you. I'm told that I excel at programing. But system administration has never been one of my talents. So it's great to have an expert to rely on when the computer decides to stump me. God bless, Bill
