If you are stuck in any stage of booting up on your Mac, below are some useful recommendations on how to resolve the issue.

1. Make Use of Safe Mode

One of the major causes of Mac not starting up properly is the incompatibility of software. It could also be because of a new operating system update that is incompatible with the current Mac you are using. Either way, booting into your Mac’s safe mode is an option to confirm and diagnose this issue.

In the safe mode, your Mac utilizes the least requirement to start up. It carries out basic checks, diagnoses on the startup disk, and performs some fixes. Here are steps to boot up your Mac into safe mode:

  • Forcefully shut down your Mac by pressing down the power button for 10 seconds.
  • On restart, press and hold the ‘Shift’ key.
  • You can release the ‘Shift’ key when you see the Apple logo and the loading screen.
  • On successful booting into safe mode, you should see the ‘Safe Mode’ inscription on the top right corner of your screen. This also streamlines the cause of the freeze in starting up to a recently installed software. Try checking all recently installed software and uninstall those that are incompatible.
