Security has always been important. Over the past years we have accumulated so many accounts for banking, social media, shopping, email, smart phones, online cloud computing, and the list goes on. Each account that we make needs to be secure and password protected. So what do we do with all of these passwords, do we remember them? write them down? use the same password for all accounts...

We will talk another day about making and the use of strong passwords. But today we are going to make a secure folder to store private documents, our work, files and passwords. We need to create whats called a "sparse image". A sparse image is a sort of file that gets bigger the more you put in it. Here are four steps to creating you very own secure imaged folder.


  • Open: Finder / Applications / Utilities/ Disk Utility.app
  • Go to: File / New / Blank Disk Image
  • Give it a name / Choose between 128-bit or 256-bit encryption
  • Choose create and give it a strong password

Open: Finder / Applications / Utilities/Disk Utility.app.

Go to: File / New / Blank Disk Image.


Give it a name / Choose between 128-bit or 256-bit encryption / Choose size.


Choose create and give it a strong password. DO NOT leave "save password" ticked.

You have now made your own secure storage. To open and use your sparse image just click on the image and it will ask you to fill in password. NEVER save this password. You can move you image to any folder or drive on your computer. When you want to save files in your image you have to open it by double clicking on the image and typing in your password. The image will mount, just like any other drive on your MAC computer and can be viewed via Finder under Devices.


When you have finished adding or changing files, ALWAYS unmount/eject the drive in your Finder, otherwise it's available for anyone logged into your account. To reopen your image after you have closed it, just double click the image and fill in your password.
