How to Fix the Disk Utility Not Loading Issue on Mac

If you have trouble loading Disk Utility on your Mac, you can take the measures below to get Disk Utility back to normal condition.

Force Quit Disk Utility

The first troubleshooting method is to force quit Disk Utility and reload your disk. Here's how:

  1. Press the Command + Option + Escape keys simultaneously to launch the “Force Quit Applications” window.

Tips
  1. You can also use Terminal and Activity Monitor to force quit Disk Utility.
  2. You may potentially lose or corrupt data if the app is actively processing data. Thus, always make sure to have your valuable data backed up before quitting any application.

Restart Your Mac

Most software bugs can be fixed with a simple restart. While your Mac is working, it generates temporary files and consumes memory. Since these temporary files are cleared and the system’s memory is reset and reallocated during a restart, a Mac restart gives your Disk Utility a fresh start. This can often troubleshoot minor glitches and potential power conflicts. You can restart your Mac by selecting the Apple menu and clicking the Restart button. When the Mac restarts, check if Disk Utility works properly.

Restart Your Mac

Restart Your Mac in Safe Mode

The Safe mode is one of the conditions of the Mac that isolates and fixes third-party apps or extensions related to conflicts. It loads your Mac with only a minimum set of drivers and system extensions. The boot to Safe mode tells you whether a software conflict is behind the problem. If Disk Utility runs successfully in Safe Mode, a third-party application or extension is most likely causing the issue. In terms of this, you can disable the problematic software and allow the Disk Utility to run normally.

Restart Your Mac in Safe Mode

How to restart your Mac in Safe mode:

  1. Shut down your Mac and wait for about 10 seconds.
  2. After pressing the Power button to turn it on, immediately hold down the “Shift” key until you see the login screen.
  3. Log in to Mac and open Disk Utility to see if it loads properly.
  4. If the Disk Utility works well in Safe Mode, restart your Mac normally to return to the regular mode.

Delete Preferences Files for Disk Utility

A corrupted preference file can lead to Disk Utility loading issues. In other words, restore the Disk Utility to its defaults by removing this file. When you relaunch the application, you’ll get a new, clean preferences file. This enables Disk Utility to load and operate correctly.

Find and Delete Preferences Files for Disk Utility
  1. Open Finder on your Mac.
  2. Press Shift + Command + G, type ~/Library/Preferences/, and press Enter to locate the Preferences Folder.
  3. Locate the file com.apple.diskutility.plist and drag the file to the Trash.
  4. Empty the Trash and restart the Disk Utility.

  6. When you finish erasing the process, click the “Done” button, and then select Disk Utility and Quit Disk Utility.
  7. In the Recovery app window, select Reinstall macOS [name], then click Continue to initiate the reinstall process.
