Why won't my Macbook Air turn on after an update?

Why won't my Macbook Air turn on after an update?

Hello,

I was using my Macbook when the Internet decided to go down so I decided to run the latest update. It seemed to be working fine but as soon as it got to a certain stage on the progress bar it would just shut down, it would then chime and the bar would start to get to the same point and repeat the previous. I tried to turn it off at the power button and turn the volume off but it seemed that my keyboard wasn't working. Now my Macbook isn't even turning itself on and off, it seems to be completely broken and won't let me turn it on. Plus this is a fairly new Macbook and I've owned it since December.

Any help would be appreciated

Thank you 🙂

If you are correctly stating that the computer does not power on when you press the Power button and there's not chime or other activity, then make a Genius Appointment and take it in for service.

My son's Macbook Air would not power on after a firmware update he did this morning. Doing the following 3 times brought it back:

1. Shut down the computer.

2. Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected

3. On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time

4. Release all the keys and the power button at the same time

5. Press the power button to turn on the computer.

Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

Beautiful! Thank you! Worked like a charm! Didnt think about clearing the SMC.

Btw, nice work Apple - pushing an update that will kill the computer...incompetent idiots!...hope you guys keep an eye on this forum.
