How to create blank disk images with Disk Utility

Christian Zibreg ∙ May 2, 2016

Should you ever find yourself in the need to create blank disk images, OS X's built-in Disk Utility is your friend. A disk image usually has a .dmg extension and appears, looks and behaves like any ordinary file, with one key exception: launching it prompts OS X to mount the volume on the desktop.

Furthermore, disk images can be used as a virtual disk for software distribution, to burn CDs or DVDs and so forth. In this step-by-step tutorial, you'll learn how to create blank disk images in Disk Utility, at any size, with optional password protection, formatting options and more.

Christian Zibreg ∙ Updated April 19, 2018

The succession of vulnerabilities found in Adobe's Flash Player shows no signs of dying down: not a month goes by without Adobe releasing another yet emergency update for Flash to patch a bunch of newly discovered vulnerabilities (measuring in the dozens).

Some of them can be pretty nasty as they introduce new attack vectors for spyware, ransomware, trojans and other malicious applications that you don't want anywhere near your computer.

A few years ago, Flash Player was impossible to avoid because a bulk of web video was encoded in Adobe's proprietary Flash format, but not anymore: YouTube, Vimeo, Facebook and many other popular web services now use HTML5-based video players that work in any modern browser.
