How to Make a Password Protected Folder on Mac. The cost-free method available with the help of the built-in Apple tools allows creating protected disk images out of confidential folders. Take note, that the way of data protection described below applies to macOS High Sierra, as well as to earlier Mac OS X versions. Aug 12, 2012 Hey what am I doing wrong. I followed all the instructions to password encrypt a folder on my Mac It creates the dmg folder, but when I click on the dmg folder it does not open & as for password. IT actually does nothing. WHat did I do wrong? Also can you use the same process to change the password on a protected folder. Now it will pop up the password settings window, here be sure to uncheck the 'Remember my password in the keychain' (the default is selected), or the password is not the same, any login to the account System people can directly double-click to open the DMG file, without the need to enter a password. So, encryption would not make sense.

A dmg file is a compressed file structure, capable of containing folders, files, etc. Dmg files can be used for a variety of purposes, from encrypting a home directory (ie – FileVault) to encrypting a file structure manually. A dmg file can be encrypted fairly simply. From Disk Utility, create a dmg file by clicking on the File menu and selecting New and then Blank Disk Image. This will bring up a screen where you can provide a name for your home folder and a size, then select either AES 128 or AES 256, which is a bit slower.Go ahead and click on Create and then at the resultant password screen go ahead and provide a password to be used. And let’s just go ahead and uncheck the option to create an entry in Keychain for the password.If you would rather do so from the command line I covered how to do so in a previous post.Now let’s download Spartan, a tool built by Ryan Kubasiak. Now download a dictionary file. I just used one of these (and for expedience sake I paired down the contents to only have about 100 possible passwords, one of which was mine). Now go ahead and open Spartan, clicking on Go! at the splash screen.At the Choose a File screen, browse to and then select your password file, clicking Choose once you have done so. At the next Choose a File screen browse to and then select your dmg file which you would like to crack the password for. The password file will then be read into RAM and the password cracking will commence.According to the length of your password this could take a long, long time, but when it’s done you will have your password, assuming it was in the dictionary of passwords you used. Dictionary files can be downloaded from a variety of sources, some collections taking up gigabytes upon gigabytes of space and covering every possible keyboard combination. Therefore, the longer the password that you use and the more complex the password is, the longer it will take to break the encryption.“So, would your holiness care to change her password?” – The Plague

I don’t know about you, but I still haven’t got over the death of TrueCrypt. It was a fantastic program for making encrypted folders in all respects, and its demise was totally unexpected.

Now I know that it has a successor – VeraCrypt – and it is more or less twin siblings. But VeraCrypt still doesn’t feel the same. And I have had lots of issues opening encrypted folders using VeraCrypt, and losing valuable files in the process.

But if you use a MacOS computer, then you don’t need VeraCrypt, because Disk Utility will make your encrypted folders for you.

Encrypted Folders With MacOS Disk Utility

It wasn’t that long ago that I showed you how to format a USB stick or SD card using Disk Utility. Many MacOS users routinely overlook Disk Utility, but it is really a nifty little program. The encryption abilities is just the icing on the cake.

An encrypted folder on MacOS has the file format DMG (similar to many MacOS software installation programs). DMG stands for “Disk Image”, and is not much different than an ISO file on Windows. Once the DMG folder has been created, you simply “mount” it to open it, and you can start dragging items in.

The process to make an encrypted DMG folder is absurdly simple.

Open Up Disk Utility

Obviously you are not going to get very far without opening Disk Utility! You will find it in the “Utilities” sub-folder of the “Applications” folder. It doesn’t matter which area of the computer is currently highlighted. When it comes time to make the disk image, you will be asked where you want to save it.

Start a New Blank Image

Go to the Menu bar and choose File–>New Image–>Blank Image.

Start Filling Out The Details Of The Encrypted Folder

Here is where you set up and configure the container to your specifications. Let’s go through each one.

• Save As : What you want it to be called on the computer. This will be the name seen by everyone who has access to your computer.
• Where : Where on the computer you want to save the newly created folder. Obviously you can move this afterwards. It is not fixed in one place.
• Name : The name you alone will see when it is mounted and open on the MacOS system.
• Size : The size you want your container to be. One important thing to note is that whatever size you specify will be instantly taken by your computer. So if you specify 100MB, then 100MB will be immediately deducted from your hard drive space – even if there is nothing in the folder yet.
• Format : Always choose MacOS Extended (Journaled).
• Encryption : See the next section for this part.
• Partitions : Always choose Single partition – GUID Partition Map.
• Image Format : If you want to add and remove files from the image file, then choose read/write disk image.

Choose Your Encryption Protocol

When you drop down the Encryption menu, you are given 2 options. 128-bit AES encryption, and 256-bit AES encryption.

Essentially, both are extremely secure, but the 256-bit version is more secure than the 128-bit version. The only downside (as the menu says) is that if you encrypt with 256-bit, you are going to see a noticeable time-lag.

However, unless you are hiding Top Secret files, or running Wikileaks from your MacOS computer, then the 128-bit version will be more than sufficient.

Set The Password

When you choose the encryption standard that you want, it will immediately ask you to set a password. Obviously it goes without saying to choose an extremely strong password. No dictionary words. Instead, a combination of letters and numbers.

If you can’t think of one yourself, you can make it easier on yourself, by clicking the key icon, and a Password Assistant will open up. Next to “Length“, slide the slider along to the number of characters you want. Under “Type”, choose which kind of password you want. As I said, the letters and numbers one is the most secure, but ultimately it is up to you.

It will then show you a password you can use under “Suggestion”, and under “Quality”, the green bar will tell you how secure it thinks the password is. If for some reason you don’t like that password suggestion, drop the menu down, and you will get lots more suggestions.

Choose one, then copy and paste the password into a secure document. If you lose the password, you lose access to the disk image!

Wait For The Encrypted Container To Be Made

When you have filled in all of the details, and you have clicked “Save”, it will create the disk image folder for you. When it has been made, click “Done”….and you are done.

Go to the Finder location where you told it to save the disk image, and it will be sitting there open waiting for you. To access it, go to the folder name in “Devices”.

Double-Click To Mount & Open The Folder

To normally open the folder (such as when it is closed), double-click the DMG file and a window will jump up, demanding the password. It should be noted at this point that you cannot copy and paste passwords into the box. You need to type them manually.

For obvious reasons, you do not want to have checked “Remember password in my keychain“. Otherwise, when you put the mouse cursor inside the password box, the password will automatically be entered!

Kind of defeats the whole purpose of encryption doesn’t it?

Drag Your Files Inside The New Window

Once you have successfully entered the password, the folder will appear in the Devices section. Click on it to enter the folder. You can now view the contents, delete files from the folder, and add new files.

When you want to close the encrypted disk image folder again, click the upwards arrow icon next to the folder name. This will dismount the folder and close it.

Conclusion

Make A Password Protected Dmg Mac

TrueCrypt and VeraCrypt may have its legions of fans (and I was one of them). But MacOS (and Windows, for that matter) have their own built in encryption tools. You just have to know where to look.
