Part 1: What Is Safe Mode?

Although it's usually confused for “Recovery Mode”, Safe Mode, also known as Safe Boot, is a diagnostic mode that starts up your Mac with a minimal set of software and drivers. It is designed to troubleshoot and isolate software-related issues that may be causing problems during startup or regular operation. When you boot your Mac in Safe Mode, it performs essential checks, such as verifying the startup disk and loading necessary kernel extensions, while preventing certain processes and programs from running automatically.

Functions of Mac Safe Mode

Mac Safe Mode serves several important functions, including:

  • Verification and Repair Of System Issues: Safe Mode verifies and repairs issues related to the startup disk and directory problems. It ensures that your Mac's file system is healthy.
  • Software Troubleshooting: By disabling non-essential processes and login items, Safe Mode helps identify if a specific application or software is causing the problem.
  • Font and Extension Management: Safe Mode disables user-installed fonts and unnecessary system extensions, making it easier to identify font or extension-related issues.

Part 2: Reasons You Might Need To Turn On Safe Mode On Mac

There are certain situations where booting your Mac in Safe Mode can be beneficial. Some of them include:

  • Incomplete Startup: If your Mac fails to complete the booting process or gets stuck at a specific point, Safe Mode can help identify and resolve the underlying issue.
  • Application Problems: If a specific application is causing stability issues or crashes on your Mac, Safe Mode can help isolate the problem by preventing third-party apps from launching.
  • Sluggish Performance: If your Mac is running slower than usual or experiencing lag, Safe Mode can help identify if third-party software or login items are responsible for the performance issues.
  • Directory Problems: Safe Mode can help repair problems with the directory structure of your Mac's startup disk, ensuring optimal performance and stability.

Part 3: How To Turn On/Off Safe Mode on Mac

Option 1: Turn On Safe Mode

The process of entering Safe Mode varies slightly depending on whether you have an Intel-based Mac or an Apple Silicon Mac. Let's explore the steps for both:

Method 1: For Intel-Based Macs:

Step 1: Shut Down Your Mac

If your Mac is on, shut it down properly by clicking the “Apple Menu”  at the top-left corner and selecting “Shut Down” from the drop-down menu.

Method 2: For Apple Silicon Macs:

The procedure to put Apple Silicon Macs into safe mode is pretty similar to Intel-based Macs. However, there's a catch.  Here is how:

Part 4: How To Confirm Whether Safe Mode Is Turned On

There are several ways to confirm if your Mac is in Safe Mode:

  • Menu Bar Reads “Safe Boot”: Look for the words "Safe Boot" in red in the menu bar. This indicates that your Mac is currently in Safe Mode.
  • Slower Performance: Safe Mode typically results in slower overall performance. This is because certain features, such as accelerated graphics, are disabled in Safe Mode.
  • System Information reads “Boot Mode”: Open the System Information window and navigate to the "Boot Mode" section. If it displays "Safe," your Mac is running in Safe Mode. Otherwise, it will show "Normal."
