How to start up your macOS in safe mode or safe boot to help resolve issues.

Use safe mode to isolate issues with your Mac:

You can use safe mode to help resolve issues that might keep your Mac from completely starting up, or to isolate other issues related to your startup disk.

What is safe mode?
Safe mode (sometimes called safe boot) is a way to start up your Mac so that it performs certain checks and prevents some software from automatically loading or opening. Starting your Mac in safe mode does the following:
1. Verifies your startup disk and attempts to repair directory
issues, if needed.
2. Loads only required kernel extensions
3. Prevents startup items and login items from opening
automatically.
4. Disables user-installed fonts
5. Deletes font caches, kernel cache, and other system cache files

If your Mac has an issue that goes away when you start up in safe mode, you might be able to isolate the cause.

Start up in safe mode
To start up in safe mode:
1. Start or restart your Mac, then immediately press and hold the
Shift key. The Apple logo appears on your display. If you don't
see the Apple logo, learn what to do.
2. Release the Shift key when you see the login window. If your
startup disk is encrypted with FileVault, you might be asked to
log in twice: once to unlock the startup disk, and again to log in
to the Finder.

To leave safe mode, restart your Mac without pressing any keys during startup.
