Part 1. Why Password Protect your Files?

Files on our Mac can be anything from documents to images to notes and calendars and many more. However, not everything in your Mac deserves to be seen by everyone. Especially your identity records.

No matter how close you are with friends and family, there are certain files you cannot share with them. You can always set and have your own piece of solitude.

This is where you can hide your important documents such as credit card information, account logins, bank account details, insurance and even legal documents. But how do you secure these files?

You need to password protect them so that no one else can open aside from you. Good thing you can enjoy the privilege of setting locks on certain folders if you are the administrator of the device.

The best part about having a folder lock is that it can help protect confidential information even if you lose your Mac or leave it unattended.

But how to lock a folder on Mac? Let's say you have a file full of back information and you don't want anyone to see it, how do you hide this file? All these and more in the next parts of this article so read along!

Part 2. How to Lock a Folder on Mac?

There are many options on how to lock a folder on Mac. Here are a few of the best methods so far.

Method 1 Disk Utility.

Before exploring other possibilities on how to lock a folder on Mac, you can take advantage of what’s free and a default part of your system.

Use the disk utility to encrypt folders without the need for more advanced tools. Although it does the basic, at least you are confident that your important folders are still password protected.

Open Disk Utility

Go to File and scroll to New and click on Disk Image Folder

Choose the desired folder you want to set up password with

Click Image

If you want the folder to be editable choose the Image format to read/write otherwise choose among the other options

Choose the encryption type to 128-bit AES encryption

Enter the desired password

Ensure that the Remember password box below in NOT checked

Click OK to confirm the action

That’s it! You have just set or locked a folder on Mac! And the best part is? It’s free! You may now delete the original folder and use the encrypted one. Larger folder files may take a while to set the encryption.

But since this setting is limited to basic functions, you might need more advanced tools to do so.

Method 2 Set Permissions on MacOS Sierra.

MacOS Sierra has set permission settings which are customizable. You can easily assign permissions to users and groups, folder and disk.

Using this option you can maximize the rights and privileges of other users on your Mac. This will also protect your details even on file sharing mode. They can see the folder but are unable to access it.

Here’s how to assign user or group:

Open desired file or folder and select File and then click Get Info

If you see that the Sharing & Permissions is not visible, click on the disclosure triangle

If the folder is locked, enter the Administrator password

Select a user or group under the Name column and set the privilege set in the pop-up menu

This is similar to the first option we gave but more specific when it comes to who might or might not be able to access your files.

3 Use Third Party Tools

If you want to be extra protective of your personal information, you can upgrade to more professional apps. Here are the best performing apps you can try to purchase for extra security:

Data Guardian 3

Espionage 3


Hider 2

Each app has its own Pros and Cons so you can check out which among these really suits your needs. But remember that these tools may cost you money.

If you don’t want to spend anything on protection, use the free options we mentioned earlier.
