Unlocking the Mystery of the Missing Power Button on Your iMac

Share This:

Are you having trouble turning on your iMac because it doesn’t have a power button? Don’t worry – you can still get your Mac up and running!

Modern iMacs don’t have a physical power button, but they do have other methods of starting up your computer. If you’re trying to power on an iMac without a power button, here’s what you need to know.

First, connect the power cable to your Mac and plug it into the wall. Once that’s done, press the shift + control + option keys at the left side of the keyboard along with the power button and hold them down for five seconds before releasing. Finally, press the power button again to turn on your Mac.

If this method doesn’t work, you may need to reset the System Management Controller (SMC). To do this, shut down your Mac completely by pressing and holding down the power button until it turns off. After that, unplug all cables from your computer (including the power adapter), wait 15 seconds, and then reconnect them all again. Finally, press and hold down both the Shift+Control+Option keys at the left side of the keyboard along with the Power Button for 10 seconds before releasing them all together. This should reset the SMC and allow you to turn on your Mac successfully.

We hope this guide has helped you turn on an iMac without a physical power button! Remember that if none of these methods works for you, contact Apple Support or take your Mac to an authorized repair shop for assistance.

Turning On an iMac Without the Power Button

It is possible to turn on your iMac without using the power button. To do so, simply press and hold the Command+Control+Power keys simultaneously for a few seconds until your iMac turns on. This will bypass the physical power button, allowing you to start up your iMac without having to physically press it. If this method doesn’t work, you may need to reset your PRAM (parameter RAM), which can be done by pressing and holding the Command+Option+P+R keys while starting up your computer. This should allow you to turn on your iMac without needing to use the power button.

Location of Power Button on Older iMacs

The power button on older iMac models is located on the back of the computer, approximately 2 inches in from the far left side and 2 inches up from the bottom edge. To find it, look for a small circle with a triangle inside; this is the power button. You may need to press firmly on the button to get it to activate. If you are having difficulty finding or pressing the power button, check your user manual for instructions tailored specifically to your model of iMac.

Turning On a Mac Without a Working Power Button

If your power button doesn’t work, you can still turn on your Mac. First, plug in the power cable. Then press and hold down the Shift+Control+Option keys on the left side of the keyboard and the Power button. Release all four buttons at the same time, and then press the Power button to turn on your Mac. If you have a recent MacBook with no removable battery, you may also need to press and hold down the Touch ID (or power) button on the right side of the keyboard for up to 10 seconds before releasing it to turn on your Mac.

The Location of the New Mac Power Button

The power button for the new Macbook Pro 13 (2022) is located in the upper right-hand corner of the laptop. It is a small, circular silver button and functions as both a power button and a Touch ID button. To turn on your Mac, simply press and hold the power button until you see the Apple logo appear on your screen.


In conclusion, the lack of a physical power button on iMacs can be a bit confusing for those who are used to the traditional Mac models with a dedicated power key. However, there are several ways of starting up an iMac without a physical power button. These include using the shift + control + option keys and the power button, plugging in a power cable, or using a Bluetooth device. With these methods, you can turn on your iMac even if it does not have a physical power button.
