Welcome to this tutorial on how to put a password on a folder on a Mac. In this guide, we will explore the step-by-step process of securing your sensitive data by adding a password to a folder. Let’s get started!

Step 1: Creating a New Folder

To begin, let’s create a new folder that will serve as the container for our protected files. This can be done by following these simple steps:

  • Open Finder by clicking on the smiley face icon located in your dock.
  • Navigate to the location where you want to create the new folder.
  • Right-click on an empty space within the directory and select “New Folder” from the context menu.
  • A new folder will be created with the default name “untitled folder”. You can change its name by clicking once on it and pressing “return”.

Step 2: Adding Files to the Protected Folder

Now that we have our folder ready, it’s time to add files that we want to protect. Follow these steps:

  • Locate the files you want to secure.
  • Select them by clicking and dragging your mouse over each file, or you can hold down the Command key and click on each file separately.
  • With the files selected, drag and drop them into the newly created folder.

Step 3: Renaming and Encrypting the Folder

To add a password to our folder, we need to rename it and encrypt its contents. Here’s what you need to do:

  • Right-click on the protected folder.
  • Select “Get Info” from the context menu.
  • In the Info window that appears, under the “Name & Extension” section, change the name of the folder to your desired name (this step is optional).
  • Check the box next to “Locked” to prevent any changes to be made to the folder’s contents without entering a password.

Step 4: Setting a Password for the Folder

Now that we have locked our folder, let’s set a password to access its contents. Follow these instructions:

  • Open “Disk Utility” from your Applications > Utilities folder.
  • In Disk Utility, click on “File” in the menu bar and select “New Image” > “Image from Folder”.
  • Navigate to the location of your protected folder and select it.
  • Choose a name and location for your encrypted disk image file, and select “read/write” under Image Format.
  • Click on “Save”.
  • You will be prompted to enter a password for your disk image file.

    Make sure it is secure and not easily guessable. Confirm your password when prompted.

Step 5: Mounting Your Encrypted Disk Image

To access your protected folder, you need to mount the encrypted disk image. Here’s how:

  • In Finder, navigate to where you saved your encrypted disk image file.
  • Double-click on the disk image file. You will be prompted to enter the password you set earlier.
  • Enter your password and click on “OK”.


If you want automatic mounting of your encrypted disk image upon login, you can go to “System Preferences” > “Users & Groups” > “Login Items” and add the disk image file to the list of items.

That’s it! You have successfully put a password on a folder on your Mac.

Now, whenever you want to access your protected files, simply mount the encrypted disk image and enter your password. Your data will remain secure even if someone gains unauthorized access to your computer.

Remember to keep your password safe and not share it with anyone.

I hope this tutorial has been helpful in guiding you through the process of adding a password to a folder on a Mac. Protecting your sensitive information is essential, and now you have the knowledge to do so easily. Happy securing!
