So, without further ado, let’s get to the steps and show you how to encrypt and password protect a folder on your Mac. Thankfully, it is effortless to put a password on a folder to shield it from others. Provide a strong password-you can use the “Key” button here for tips on creating a strong one.You may have sensitive files like documents, images, videos, voice notes, that you want to keep private from friends and family (if they ever happen to use your Mac). When you opt for an encrypted drive, you’re also prompted to create an encryption password for your disk image. Image Format: Select “read/write disk image” so you can read from and write to the disk image at any time.Partitions: Select “Single partition – GUID Map” to use a single partition inside your disk image file.If you’re encrypting sensitive files, you’ll probably want to choose 256-bit and accept the slight slow-down for more security. 256-bit is more secure, while 128-bit is faster. Encryption: Choose either 128-bit or 256-bit AES encryption.Format: Select Mac OS Extended (Journaled) as the file system.You can enlarge or shrink the disk image later, if you need to. So, for example, if you create a 100 MB disk image file, it takes up 100 MB of hard drive space, even if you have’t move any files inside it yet.

The container file takes up the maximum file size immediately, no matter how many files you put inside.

For example, if you choose 100 MB, you’ll only be able to store up to 100 MB of files inside it.
