How do I boot a Mac in Safe Mode?

Answer 1

Booting in Safe Mode

Start of Restart your Mac > immediately press and hold the Shift key

You'll see the Apple logo appear on the screen

Let go of the Shift key once the login window appears

If FileVault is encrypted on your computer, you'll need to login twice: once for the StartUp Disk and the second for Finder

When you're ready to leave SafeMode, Restart the Mac without pressing any keys on the keyboard
