Creating a locked folder on a Mac desktop is a straightforward process that helps enhance the security of your sensitive files. This guide will walk you through the steps of creating a password-protected folder using built-in macOS features. By the end, you’ll know how to safeguard your data effectively.

How to Create a Locked Folder on Mac Desktop

To make a locked folder on your Mac desktop, you can use the Disk Utility app to create an encrypted disk image. This method allows you to store files securely within a virtual disk that requires a password to open.

Step-by-Step Guide to Create a Locked Folder

1. Open Disk Utility: You can find Disk Utility by searching in Spotlight (press Command + Space and type "Disk Utility") or navigating to Applications > Utilities > Disk Utility.

2. Create a New Image:

   • Click on "File" in the menu bar.
   • Select "New Image" > "Blank Image".

3. Configure Your Disk Image:

   • Save As: Choose a name for your disk image file.
   • Name: Enter the name you want for the mounted volume.
   • Size: Choose a size that accommodates the files you plan to store.
   • Format: Select "Mac OS Extended (Journaled)".
   • Encryption: Choose "128-bit AES encryption" for a good balance of security and performance.
   • Partitions: Select "Single partition – GUID Partition Map".
   • Image Format: Choose "sparse bundle disk image" for a resizable image.

4. Set a Password: After selecting encryption, you’ll be prompted to enter a password. Ensure it’s strong and memorable but avoid using the "Remember password in my keychain" option for maximum security.

5. Save and Mount: Click "Save" to create your encrypted disk image. Double-click the image file to mount it, and enter your password to access the folder.

6. Store Your Files: Drag and drop files into the mounted disk image. Once finished, eject the disk image to lock it.
