How to boot your Mac and use it in safe mode

However, if you don’t know how to boot your Mac into safe mode or what you need to do to fix your device after doing so, you can find everything you need to know below.

What is Safe Mode on Mac?

Safe Mode is a simplified version of the Mac desktop that loads only the minimum elements needed to boot and run the device. Start by checking the boot disk for problems and boot the operating system without using third-party extensions, boot programs, or user-installed fonts. It also clears certain areas of the system cache (such as the kernel cache).

This helps identify the reason behind the persistent problem of the operating system. For example, if a non-optimized or corrupted boot item is causing your Mac to slow down, booting in safe mode will immediately reveal it. You can then look at the programs that launch with macOS and take the necessary actions.
