Here is the quick and easy way I store my important files on my Mac only using tools already installed every Mac.
In a nutshell, we are going to create a password encrypted vault, or as Apple calls it, a disk image. This vault will act like any other file that we can put on Dropbox or on a flash drive. However, with the password, you will be able to decrypt and open it up to drag files in and out as you see fit. Then, once you eject it, it will go back to its safe, encrypted state with all of the files inside completely inaccessible to anyone without a password.
The easiest way to open up Disk Utility is to use Spotlight (the little magnifying glass in your menu bar) to search for it.
It can also be found at
Applications > Utilities > Disk Utility.
Disk Utility should open up to a window like what you see below.
You’ll need to create a new image. You can do this by using the
or by clicking
File > New Image > Blank Image... You should see a screen like
Click “Choose” and “Save” to finish creating your vault.
If you open up a new Finder window, you should see your sparsebundle file where you saved it. That’s your vault file.
Also, in the sidebar under “Devices”, you should see your mounted image. Click that to see your unlocked vault all ready to drop files in. Just make sure that you eject it once you are done. That will encrypt and lock it.
