How to Turn On a Mac Computer

As long as your Mac is plugged into a power outlet, you should be able to turn it on by simply pressing the power button. That power button will be located somewhere slightly different depending on which Mac you're trying to power on, however.

Mac Studio

To turn on a Mac Studio, press the power button located on the rear left-hand side (from the front), located next to the 3.5mm headphone jack. It's a circular button with a power symbol on it.

Mac mini

The power button for the Mac mini is located on the rear right-hand side (from the front) next to the power cord port. It's a color-coded button with a white power symbol on it.

The latest-generation iMac also has a power button on the rear. It's located on the left-hand side (from the front) and is isolated from the other ports. It will be the same color as the chassis and feature the typical power symbol.

What to Do If Your Mac Doesn't Turn On

The power button on your Mac should be all you need to do to turn it on. If it powers up but doesn't turn on as it should, you'll want to look at our Mac start-up troubleshooting article. If it doesn't turn on at all, though, there are some things you can try.

The first step should be to check the power cable is plugged in properly to the Mac and the wall. If in doubt, unplug them and plug them in at both ends to be sure. Also, make sure the wall socket is turned on, if necessary.

If you're using a power strip, try testing it with a device you know works to see if that's the cause of your Mac not turning on. The same goes for any multi-port power adapters or surge protectors you use.

Is your Mac particularly hot? If you're trying to use your Mac in the middle of a heatwave, it might not be turning on to conserve its components' health. That's unlikely, but in extreme conditions may cause a Mac not to power on. If that is the case, wait until it's cooled down and try again.
