What Is Mac Safe Mode?

Mac Safe Mode is a Mac snap-in mode. It is available on all Mac computers like MacBook Pro, MacBook Air, iMac, etc. It can boot your Mac computer without starting some software like startup programs, system extensions not required by macOS, and fonts that are not installed by macOS. Besides, it can also check your startup disk to find and fix errors like running First Aid in Disk Utility.

Due to these features, it can help you find whether it is a software issue or a system problem that happens to your Mac. Besides, it can delete some system caches like font caches and the kernel cache. Don’t worry, these caches can be automatically created again when necessary.

So, Mac Safe Mode is particularly useful when you want to solve and isolate some issues that don’t seem to be associated with using any particular app on your Mac computer, like iMac won’t boot past the Apple logo, your computer was restarted because of a problem, Mac won’t boot into Recovery Mode, and more.

How to Use Mac Safe Mode?

Recover Your Mac Data in Safe Mode

If your Mac is unbootable due to some reasons like virus attack, system crash, hard drive failure, etc., and you want to recover your Mac files, you can do it in Safe Mode.

Firstly, you need to select a reliable Mac data recovery software. You can try Stellar Data Recovery for Mac. It has a trial edition and you can first use it to scan the drive you want to recover from. If you can find your needed files from the scan result, you can upgrade the trial edition to an advanced edition and then recover your data. You can go to the MiniTool official download center to get this software.

1. Open the software on your Mac.

2. When you see the following interface, you need to select the data types you want to restore. You can also directly turn on the button for Recover Everything to scan all types of files.

3. Click the Next button to continue.

4. On the next interface, you need to select the drive you want to recover data from. If you want to perform a deep scan, you can enable the button for Deep Scan.

5. Click Scan to start scanning.

6. After scanning, you can see the scan results. Then, you can check whether your needed files are included. If yes, you need to register this software and then recover these files to a suitable location (an external data storage drive is recommended).

In Mac Safe Mode, you can also analyze the issues on your Mac.

If the Issue Persists in Mac Safe Mode

If the issue still occurs in Safe Mode, you need to reinstall macOS to make sure that you are running the latest macOS and all your Apple software and third-party apps are up to date. On the other hand, if your Mac computer restarts several times and then shuts down while booting up in Safe Mode, you can also reinstall macOS to have a try.

If the Issue Disappears in Mac Safe Mode

If the issue doesn’t appear after you boot your Mac into Safe Mode, you can exit Safe Mode and boot your Mac as usual. In most cases, the issue should be solved.

If the issue returns, some Mac startup programs should be the cause of the issue. However, it is difficult to find which app causes the issue. The thing you need to do is to update macOS and any software on your Mac computer.

How to Update macOS?

1. Click the Apple menu at the top-left corner on the screen and then select Software Update.
2. There will be a pop-up window, on which you can see whether there are available updates. If yes, you can click the Upgrade Now button to install all available updates.

This process can not only upgrade your macOS but also install updates for all your installed programs.

However, if software updates can’t solve your issue, you can try these things:

1. Disable all startup items and then restart your Mac. Next, you can re-enable them one at a time and restart your Mac after each to find out which login item is the real cause of the issue.
2. At times, it is a software issue in your current user account that causes the issue. To rule out this possibility, you can set up a new user account on your Mac and then reproduce the issue in the new account.
3. Remove all accessories from your Mac computer. Such devices include printers, drives, USB hubs, and other unnecessary devices.
4. Reinstall macOS.
