AdBlock for Safari is a fast and powerful Mac app that speeds up web browsing in Safari by blocking ads that clog web pages. AdBlock starts blocking ads on millions of websites, including Facebook, YouTube, and Spotify, from the moment it's installed. In this article, you’ll learn how to install the AdBlock for Safari app on your Mac.


What is the AdBlock for Safari app?

The AdBlock for Safari app, first released in 2018, is the "next-generation" version of the AdBlock for Safari extension that has been around since 2009. Although you can still use the old AdBlock extension for now, Apple is making Safari extensions obsolete. We recommend that you switch to the new app by the end of the year.


The AdBlock for Safari app consists of three components:

  1. AdBlock Engine, a browser extension that uses content blocking rules (filter lists) to determine what to block and hide on websites you visit

  2. AdBlock Icon, a browser extension that adds a button to the Safari toolbar, allowing you to control the AdBlock app from within Safari

  3. The AdBlock app, where you can manage your filter list subscriptions and whitelist (sites where you have allowed ads to appear)


Both extensions are required for the AdBlock app to work.

  1. If our legacy AdBlock extension is installed when you update to Safari 12, click the AdBlock icon on the Safari toolbar. You will see the following notice in the AdBlock menu:

  2. Click the We've made changes to AdBlock! link. AdBlock's options page opens with the following notice:

    (Although we recommend you switch to the AdBlock app now, you can continue using the extension for a little while longer. If you decide to stay with the extension for now, please click the Learn more link to find out what has changed.)

  3. Click the AdBlock for Safari Mac App link. A Mac App Store Preview page opens. If the App Store itself doesn't open momentarily, click View in Mac App Store.
