Do you want to protect your sensitive files and folders on your Mac? One of the most effective ways to secure your data is by locking folders. In this tutorial, we will guide you through the process of locking folders on your Mac using built-in features and third-party applications.
Method 1: Using Disk Utility
Open Finder and navigate to the Applications folder. Then open the Utilities folder and launch Disk Utility.
In Disk Utility, click on New Image, located in the toolbar.
A pop-up window will appear. Choose a name for your disk image, select a location to save it, and set the size according to your needs. Make sure to choose “read/write” for Image Format and “Sparse Bundle Disk Image” for Encryption.
