How to Protect Sensitive Files with Disk Utility
That’s where encrypting and protecting your data with additional security passwords comes in. There’s no need to spend money on expensive third-party apps. All you need is Disk Utility (it’s baked into macOS) and a few minutes of your time.
Familiar with FileVault protection. While it’s a good way to protect your entire hard drive, doing so can be time-consuming. If you need to enable protection on just one specific file or folder, try an alternative method. With the macOS Disk Utility tool, you can protect your private files and create an encrypted folder disk image relatively easy. Let’s show you how.
Time to start encrypting
First, launch Disk Utility. To open the Utilities folder, use the Command + Shift + U key combination from Finder. Then, double-click on the Disk Utility icon.
When Disk Utility opens, click the File menu at the top. Then, choose New and select Image from folder.
Select the folder you want to encrypt (in our example, we called it My secret folder) or create a new folder and add your files to it. Click on “Choose”.
Type the name for your encrypted disk image and select the 128 or 256-bit encryption option. Then, click Save and set up your password for the encrypted image.
Note: Remembering this password is extremely important. You might want to even write it down and keep it in a safe or somewhere secure. If you forget it, you’ll lose access to everything that’s encrypted inside this folder. It’s one of the only drawbacks of this encryption option.
That’s it. Now you know how to encrypt and enable a password for a specific item or folder with Disk Utility. Feel free to leave your comments. And be sure to check the latest MacKeeper blog for more info on how to get the most out of your Mac.
