Steps to Password Protect Folders on Mac
Follow the steps below to Password Protect Folders on Mac using the Disk Utility Program as available on your Mac. Disk Utility Protects Folders by creating an encrypted disk image of the Folder which can only be opened by entering a password.
1. Click on the Finder Icon on the Task-bar of your Mac.
2. Next, click on Applications in the side-menu and then double-click on the Utilities Folder (See image below)
3. In the Utilities Folder, double click on Disk Utility program.
4. Once Disk Utility opens, click on the File option in the top-menu bar of your Mac. Next, hover your mouse over New Image in the menu that appears and then click on Image from Folder option in the contextual menu (See image below).
5. In the Disk Utility Window, select the Folder that you want to password protect and then click on the Open button
6. In the next window, provide a Name for your protected Folder (in Save As box) and select the Location for the Encrypted Folder (in Where box) – See image below
7. On the same screen, select the level of Encryption of the protected Folder (in Encryption box) – See image below.
As you can see in image above, you can either go with the recommended 128-bit AES encryption or choose 256-bit AES Encryption option. While 256-bit Encryption provides more security, it is slower and takes up more resources and time (See image below).
8. Once you choose the Level of Encryption, you will see a pop-up prompting you to create a password. Enter a Password for the Encrypted Folder, verify the Password by entering it again and then click on the Choose button (See image below).
Important: Make sure that you write down the password and keep it in a secure place. You won’t be able to access the Protected Folder without entering your Password.
9. Next, choose read/write option in the “Image Format” box and click on the Save button. Choosing read/write option for the Image Format will allow you to both view the Password protected Folder and also make changes to it (See image below).
10. Wait for your computer to finish the process of Encrypting the Folder. The time to complete will depend on the amount of data located in the folder to be protected.
11. Click on Done once you see a pop-up informing about completion of the process (See image below)
