Learn Mac Safe Mode Easily with A Walkthrough Guide

Do you need to learn how to start Mac in Safe Mode? If your Mac is running slowly, freezing, or showing errors you don’t understand, booting into Safe Mode can help. But before that, what is it actually all about? You may have already heard about this specific mode while browsing online, from friends, or from other Mac users who have experienced issues with it.

But today, this article will help you explore Safe Mode's purpose, functions, and how to use it to resolve your Mac issues. Aside from that, other methods and information will also be covered, including the right actions to take if it doesn’t work and a recovery tool in case you experience data loss along the way. That said, start learning with the sections below.

Part 1. What is Safe Mode?

If you want to start Mac in Safe Mode, let us first determine what it does and why it’s needed. Basically, Safe Mode is a special way to start your Mac with only the essential software it needs to run. This way, the computer will skip most startup programs, remove temporary files, and check your startup disk for problems, helping you determine whether the issue is caused by a program or by your Mac's system. If your Mac works well in Safe Mode, the problem likely comes from something you installed. On the other hand, if the issue—such as lagging or freezing—persists, it may be caused by your Mac's hardware or system files.

Part 2. Core Differentiation: Which Mac Do You Have?

Now that you have an idea of what Safe Mode is, it's time to boot your Mac into it. Just note that the method will depend on your Mac model. Use the appropriate guide below depending on whether your Mac has Apple Silicon (M-series chip) or an Intel processor.

Method 1: Apple Silicon (M1, M2, M3, M4 chips)

Newer Macs that use Apple Silicon chips, such as the M1, M2, M3, or M4, can enter Safe Mode by using the power button and the startup options screen. Unlike older models, this method presents various options first rather than booting directly into the mode. Just shut down your Mac completely, then press and hold the power button until you see “Loading startup options.” From the screen, select your startup disk, long-press Shift, then click Continue in Safe Mode.

Method 2: Intel-based Macs

Meanwhile, this method is for older Macs that use Intel processors. It is more straightforward since you only need to turn on or restart the computer, then quickly press and hold the Shift key as soon as you see the Apple logo. From there, simply keep holding it until the login window appears. You can release it afterward to log in to your Mac. You will know you successfully booted into the mode for both methods if you see Safe Boot in the upper-right corner.

Part 3. What to Do While in Safe Mode

Once you boot Mac in Safe mode, use this time to find and fix the problem that's been delaying your work. Below are three common actions you can take while in Safe Mode.

Option 1. Isolating Software Conflicts

Sometimes, login items or programs that automatically open when you turn on the Mac cause the problem. But in Safe Mode, these automatic programs don’t immediately open. So, if the computer works fine, it likely means at least one of them is the problem. In this case, simply check the list of programs that start on your Mac and turn off any that may be causing the issue. You may also disable others you don't use or need.

Step 1While in Safe Mode, launch your Mac’s System Settings and select General. From there, click Login Items & Extensions to view your login items and programs.

Step 2Review the list and turn off any programs you don't need or that you suspect might be causing the problem.

Option 2. Clearing System Caches

As with other computers or devices, the system caches are part of your Mac's data, helping tasks or processes load faster. However, these can accumulate and become corrupted over time, causing the Mac to run slowly. Don’t worry, though. You can clear system data storage on Mac. In fact, simply booting into macOS Safe Mode already clears certain caches. But to clean more thoroughly, clear your other user caches in Finder..

Step 1Open Finder and press Shift + Command + G to open the Go to Folder window. Next, type ~/Library/Caches and press Enter to open your user cache folder.

Step 2Simply select the files inside the folder and move them to the Trash. You should also remember to empty the Trash afterward to permanently clear them before restarting the Mac.

Option 3. Disk Utility

Safe Mode also lets you open Disk Utility, a built-in tool on Mac that checks for storage errors. You can run the First Aid feature to scan your startup disk for errors and repair them if possible. It is a suitable solution if your Mac’s storage is the cause of the problem.

Step 1Launch Finder to open Applications and start Disk Utility. After that, select your startup disk from the list on the left side of the window.

Step 2At the top of the window, select the First Aid button and hit Run to confirm.
