If you are having trouble with your device, you might have asked yourself why won’t my iMac turn on.
It can be frustrating when your computer won’t start up, but there are several reasons why this might be happening.
In this article, we will explore some common causes of iMac startup issues and provide solutions to help you get your computer up and running again.
One possible reason why your iMac won’t turn on is a problem with the power source.
Check to make sure that your computer is plugged into a functioning power outlet and that the power cord is securely connected to both the computer and the outlet.
If you are using a MagSafe power adapter, look for the LED light on the adapter to confirm that the battery is being charged or is fully charged.
If the power source is not the issue, then there may be a problem with your computer’s hardware or software.
Another possible cause of iMac startup issues is a problem with the hardware.
Loose cables or damaged hardware components can prevent your computer from turning on.
If you suspect that there is a hardware issue, try disconnecting all peripherals and external devices from your iMac and see if that helps.
If you are still having trouble, you may need to take your computer to a professional for repair.

Basic Troubleshooting
If your iMac won’t turn on, don’t panic.
There are a few basic troubleshooting steps you can take to try and get your computer up and running again.
Check Power Supply
First, make sure your iMac is properly connected to a power source.
Check that the power cord is securely plugged into both the back of your iMac and an electrical outlet.
If you’re using a power strip, make sure it’s turned on and functioning properly.
If you’re using a laptop, make sure the battery is charged.
If your iMac is properly connected to a power source and still won’t turn on, try resetting the SMC (System Management Controller).
The SMC controls many of the basic functions of your iMac, including power management.
To reset the SMC, follow these steps:
- Shut down your iMac.
- Unplug the power cord from the back of your iMac.
- Wait 15 seconds.
- Plug the power cord back in.
- Wait 5 seconds, then turn on your iMac.
Restart Your iMac
If your iMac still won’t turn on, try restarting it. Press and hold the power button on the back of your iMac until it turns off.
Wait a few seconds, then press the power button again to turn it back on.
If your iMac still won’t turn on after trying these basic troubleshooting steps, it may be a hardware issue.
You should contact Apple Support or take your iMac to an Apple Store for further assistance.
Advanced Solutions
If the basic solutions did not work for you, don’t worry, there are still some advanced solutions you can try.
Reset The System Management Controller (SMC)
Resetting the SMC may help if your iMac won’t turn on, or if it turns on but doesn’t behave as expected.
Here’s how to do it:
- Shut down your iMac.
- Unplug the power cord and any other cables connected to your iMac.
- Wait for 15 seconds.
- Plug the power cord back in.

Boot In Safe Mode
Booting in Safe Mode can help you identify and fix issues that prevent your iMac from starting up properly.
Here’s how to do it:
- Press and hold the power button on your iMac until it turns off.
- Press the power button again to turn on your iMac.
- Immediately press and hold the Shift key.
- Release the Shift key when you see the login window.
Your iMac will now start up in Safe Mode. In Safe Mode, your iMac will only load necessary system files and drivers.
If your iMac starts up in Safe Mode, it means that there might be an issue with a startup item or a login item.
Run Disk Utility
If your iMac still won’t turn on, you can try running Disk Utility to repair any errors on your startup disk.
Here’s how to do it:
- Boot your iMac into Recovery Mode by holding down Command + R while your iMac is starting up.

After running Disk Utility, try restarting your iMac to see if it turns on.
Remember that these advanced solutions should only be attempted if the basic solutions don’t work.
If your iMac still won’t turn on after trying these solutions, it might be time to take it to an Apple Store or authorized repair center for further diagnosis and repair.
