The Ultimate Guide to Fixing the Mac Won't Turn On Issue

Mac computers are renowned for their reliability, but sometimes they can develop problems. One of the most frustrating issues is when your Mac won't turn on. In this ultimate guide, we'll take you through some steps to diagnose and fix the problem.

Step 1: Check the Power Source

The first step is to ensure that your Mac is correctly connected to a power source. Check that the power cable is firmly plugged into both your Mac and the power outlet. Also, ensure that the power outlet is working by plugging in another device.

Step 2: Reset the SMC

The System Management Controller (SMC) controls various hardware functions on your Mac, including power management. Sometimes, resetting the SMC can resolve issues that prevent your Mac from turning on. The method to reset the SMC varies depending on your Mac model.

Mac desktop computers (except Mac Pro):

  • Shut down your Mac
  • Unplug the power cable
  • Wait 15 seconds
  • Plug in the power cable
  • Wait for 5 seconds and turn on your Mac

Mac laptops:

  • Shut down your Mac
  • Hold down the Shift, Control, and Option keys, along with the Power button, for 10 seconds
  • Release all keys and wait for 5 seconds before turning on your Mac

Step 3: Check the Display

If your Mac appears to be turned on, but you can't see anything on the screen, there may be an issue with the display. Try adjusting the brightness and contrast. If that doesn't work, try connecting an external display to see if the problem is with your Mac's display.

Step 4: Reinstall macOS

If your Mac still won't turn on, you may need to reinstall macOS. This process will erase all data on your Mac, so ensure you have a backup before you proceed.

  • Start your Mac in Recovery mode by holding down Command+R while turning on your Mac
  • Choose 'Reinstall macOS' from the options
  • Follow the on-screen instructions to complete the installation
