How to remove Adobe Flash from your Mac

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.

While Apple does block older, vulnerable versions of Flash in the Safari browser on macOS, you should do yourself a favor and remove Flash Player from your Mac using step-by-step instructions provided in this tutorial.

In this tutorial, we'll show you how you can configure automatic downloads on your Mac so you have better control over the content that is downloaded to your machine.
