Encrypt A Folder In Mac

Encrypting Folders in Mac

  1. Firstly, open up Disk Utility.
    Disk Utility
  2. Then, click on File > New > Disk Image From Folder.
    New Image from Folder
  3. Select the folder you want to encrypt, and click Image.
    Select Folder to Image
  4. Choose ‘read/write’ if you want your folder to be edit-able (if not, just choose another format), and choose ’128-bit AES encryption’.
    Choose Image Format and Encryption
  5. Type in any password you desire, and very importantly, make sure the checkbox for ‘Remember password in my keychain’ is NOT ticked, else it will defeat the whole purpose of encrypting your folder.

And that’s it! A password-protected .dmg file will be created based on the folder you selected.Larger folders may take longer to encrypt. Once that is done, you can delete the original folder.
Encrypted DMG File
To access the encrypted disk image, just double-click the .dmg file to mount it in the Finder and punch in the password whenever you try to access the folder. Always uncheck the box saying "Remember password in my keychain" to make sure it is always protected by passwords.

After a disk image is mounted, you’re able to access the folder like normal. Now, putting any files in the folder will put the file under encrypted protection too.

After you’re done working with the folder and want it to be password protected again, just unmount the folder from Finder.
