Since Safari 10 was introduced with macOS Sierra in 2015, Adobe’s Flash Player has been disabled by default. This means that from time-to-time, when browsing the web on your Mac, you will see alerts that there is a “Missing Plug-In”, or requests that you install the Flash Player.
Flash has been removed by default because Apple doesn’t want to leave customers exposed to Flash vulnerabilities. However, while Apple isn’t exactly a fan of Flash – back in April 2010 Steve Jobs penned his “Thoughts on Flash,” indicating that he thought its days were numbered – Apple doesn’t stop you from installing Flash on your Mac.
You may find that you don’t need Flash though. The chances are that you will be able to happily browse the web without installing Flash at all, as the tool has already been assigned to history – especially since Adobe confirmed in 2017 that: “Adobe is planning to end-of-life Flash”.
There are some older sites and services that still require Flash to run, and you may want to use one of them. If that is the case, we will show you how to install it – and how to make sure that it is safe to do so. If you do want to run Flash content on your Mac you will need to follow the link to Adobe’s website and install the latest version of Flash.
Note that even after you have installed Flash on your Mac, it won’t necessarily remain there. Flash tends to disappear from your Mac every time you update the Mac operating system, so you may need to install Flash again in the future.
If you have chosen to install Flash in order to view video and other content, and later decided to uninstall it, this article outlines how to uninstall Flash Player on Mac.
