A folder on Mac can contain multiple PDF files, photos, business contracts, invoices, or proposals. To ensure the security of your folder containing sensitive information or private data, it’s recommended to password protect folder on Mac. Locking the folder indicates that only those individuals can access your folder to whom you have provided the password.
Without knowing the password that you have created, no one can open the locked folder on your MacBook. It can save your data from copying or getting edited unnecessarily.
There are multiple benefits of locking a folder on your MacBook. Read the following reasons to know why you should password protect folder on Mac:
- Sensitive information like business projects, invoices, and contracts should be kept secured on your MacBook to avoid any inconvenience in the end. For this, locking the folder is the best option.
- If your kids use your MacBook to play games, but they accidentally edit or delete your files, the only way to protect your data is by locking it in the folder. By doing so, your kids cannot access the locked folder, and all your files will be secured.

- If you have your personal or family photos saved on your system, it's ideal for securing them through a locked folder. It will protect your personal photos from getting copied or accessed, especially if many people use your laptop on a daily basis.
Mac constantly tries to upgrade its security and privacy to ensure a well-protected environment for its users. Disk Utility is the built-in feature of the Mac that allows the user to lock a folder on the Mac. For this, make sure to gather all your important files in the folder to secure them through Disk Utility. Read the following steps to learn how to put a password on a folder on Mac:
Step 1: Navigate to the feature of "Disk Utility" and open it. Go to its "Menu Bar" and click on the "File" button.
Step 2: Now select "New Image" and then click on "Image from folder." Once done, choose the folder that you want to lock through a password.
Step 3: Select the encryption level that is either 128-bit or 256-bit. Now enter the password through which you want to lock the folder. After verifying the password, you can also name the folder accordingly.
Step 4: In the section "Image Format," choose the "read/write" format from the menu. Once done, click on the "Save" button. The locked folder will be displayed next to the folder you have selected to password protect if you have not selected a different location for it to be saved.
If you don’t want to utilize the Disk Utility feature, you can still password protect your PDF file on Mac. You can use the Preview app to secure your data and information flawlessly. However, you can only password protect individual files through the Preview app, not an entire folder. In this section, we will use the Preview app to lock important files efficiently:
Step 1: Go to the Preview app on your MacBook and open the PDF file that you want to lock. Once done, go to the "File" button and select "Export" from the drop-down menu.
Step 2: At the bottom of the menu, locate the option of "Permissions." Tap on this option to set the file permissions and the password. Now enter a strong password and verify it. Once done, click on the "Apply" button.
When it comes to locking any folder on your MacBook, there are two options that you can utilize. First, you can lock your folder through an encrypted password. In the second scenario, you can protect your folder from getting unintentionally deleted or modified through a lock. Here, you don't require a password; instead, the system shows a warning notification whenever you try to delete the locked file or folder.
Sharing and permissions of file settings are usually adjusted when there are multiple users of a MacBook. In the sharing and permission settings, you can see three options that are read-only, write-only, and read and write. In the read-only option, you can only read the document and will be restricted from modifying it. Through the write-only setting, the folder becomes a drop box, and the person with this permission can only copy the items to the drop box but can’t access the files in that drop box.
On the other hand, through the read and write option, the user can perform both of the functions without any restriction. By choosing among these options, you can adjust the permissions according to the user.
