How to remove or update Flash Player on a Mac, fix blocked Flash plug-in

Karen Haslam | June 21, 2016
Flash Player seems to be one of the most insecure and pointless pieces of software, so with yet another security vulnerability we ask if it might be better to remove it all together

Adobe Flash has caused many problems in the past, with critical vulnerabilities being exposed right after the company releases security updates. 

The security flaws have affected Flash for Windows, Mac and Linux. With Flash already assigned to history, these vulnerabilities aren't helping its survival. 

You might have also seen telltale "Blocked Plug-in" when attempting to view Flash content in Safari - all of which leads to us and Apple suggesting that you should stop using Flash Player all together and adopt HTML5 content.

In macOS Sierra, Safari 10 now disables Adobe's Flash Player by default - an option you had to previously select to disable. Suggesting Apple no longer wants its customers to be exposed to Flash vulnerabilities and wants you running on HTML5, the newer, safer way of browsing the web.

How to uninstall Flash Player on your Mac

Download the uninstaller from Adobe. You can find it here.

There's a different version depending on the age of your operating system. The newest is for OS X 10.6, but don't worry, it covers all subsequent versions of the OS.

Launch the uninstaller from your Downloads folder on your Mac.

When the uninstaller runs, click Uninstall.

Enter your admin password and close all your browsers.

When the uninstaller has finished it is also wise to delete a couple of folders, according to Adobe. These can be found in the home directory's Library folder. Go to Finder, click Go in the menu and hold down Alt (or Option) to make the Library folder appear as a drop-down menu. Locate these two folders and delete them:

~/Library/Preferences/Macromedia/Flash\ Player

~/Library/Caches/Adobe/Flash\ Player
