What Causes MacBook or iMac Failing to Turn on

Opposite to Mac won't shut down, Mac won't turn on is an issue that Mac users have been facing in the past. There are various reasons which can prevent your Mac from booting. Let's see the possible reasons behind the startup failure on Mac:

  • Component Failure: Your Mac works using a keyboard, screen, SSD drive, battery, and touchpad. If any component is misbehaving, it can prevent your Mac from startup.
  • System Management Controller (SMC) Problem: SMC is responsible for handling all the power supplies to your Mac. So, whenever you turn your Mac on, SMC does its job to handle all power-related issues. If SMC fails, your Mac won't boot.
  • Battery: Without a power cable, your Mac runs on the battery. If your battery is insufficient, your Mac won't work.
  • Broken Applications: Any firmware or startup application misbehaving or not working can also cause problems with Mac startup.

These are some of the key reasons that can create problems for your Mac.
