![]() Folders can’t be directly encrypted in macOS, but you can put them in password-protected containers. This has the effect of protecting your folders and the files they contain with a password. You can password-protect folders on macOS using the built-in Disk Utility application or a third-party tool called Encrypto. Using Disk Utility You can password-protect the contents of a folder by copying them to a password-protected disk image. This will create a new dmg file which will be password-protected. The original folder will remain untouched and can be deleted once the contents of the disk image are confirmed. Open Disk Utility from Spotlight or “/Applications/Utilities/Disk Utility.app.” 2. Choose “File -> New Image -> New Image from Folder” from the menu bar. Select the folder you want to password-protect from the pop-up file browser window. In the “Encryption” menu, choose “128-bit AES Encryption” or “256-bit AES encryption.” The second choice is nominally more secure but takes longer to encrypt and decrypt. Both formats are sufficiently secure for protecting your data, so the faster 128-bit AES is typically recommended. Set a password on your PDFs if you don't want everyone to see them. And here is how you can do To password protect PDF, first open the document you want to secure in PDF Expert for Mac. Use a minimum of 12 characters; Don't use dictionary words and their obvious substitutions; e.g. Nov 13, 2018 - A document can have only one password. If you change an existing password when you share a document with others, the new password. Enter a password when prompted. This is the password you will enter to unlock the disk image. It should not be the same as your Mac password. Make sure it is sufficiently difficult to guess. In the “Image Format” menu choose “read/write” to allow you to add files to the image. Otherwise, you will only be able to view the files on the image without updating them or adding new files to the image. Click “Save” to create the encrypted disk image. This will start a short process in Disk Utility which will notify you when it is finished creating the disk image from your folder. Unless you select a different save location in the previous steps, the disk image will appear next to the folder you selected. This DMG file is not the same as your folder, but it is a copy of the folder’s contents in a disk image format. ![]() That disk image is protected by a password, requiring a password before it can be mounted and read. The original folder has been untouched and is not encrypted. Open the disk image and enter your password to confirm you can access the image and that it contains all of the folder’s files. Once you’re sure everything worked smoothly, delete the unencrypted folder. This will leave only the encrypted DMG behind.

It provides greater ease of use in encryption and decryption, based on a simple drag-and-drop procedure.
