Not able to use Safe Mode on your Mac? Check out how to fix Mac won't start in Safe Mode in this article.

Safe Mode is an excellent technique to troubleshoot various Mac issues.

If your Mac isn't working properly, one way to troubleshoot it is to boot it into Safe Mode, which is a limited environment that only loads Apple-supplied applications for basic functioning.

To enter Safe Mode, restart your Mac while holding down the Shift key, but, in certain circumstances, this will not work, and the machine will either run normally or have difficulty and hang without booting at all.

The failure to boot into Safe Mode may occur due to the system being configured with encryption or other security settings that restrict booting to such modes, peculiarities in how wireless keyboards deliver boot arguments to the system, or file system issues.

What is Safe Mode?

Safe Mode is a restricted environment in which the operating system only uses the resources required to execute the system. When you boot your Mac into Safe Mode, it only loads programs and apps that are native to Apple and deemed required for Mac functionality.

Third-party apps, non-essential native apps, fonts not installed by macOS, system extensions not required by macOS, and so on are not launched. In Safe Mode, the OS performs this to deliver the best possible performance with the current system settings.
