<p>2021-09-23</p>

<p>I have an old 2011 MacBook Air that is running the latest version of macOS Catalina thanks to the very wonderful <a href="http://dosdude1.com/catalina/">Catalina Patcher</a> by dosdude1. This project has made it possible for me to run and test some of the latest software from Apple - namely Safari 15.</p>

<p>I ran into a small bug early on though – Safari extensions couldn’t be activated via the preferences menu. Luckily I discovered a very simple fix. My hope is this might help others (as small of a demographic that might be) who run into the same issue with the Catalina Patcher.</p>

<ul>
<li>Close&#47;Quit Safari completely</li>
<li>Open the Finder and use the shortcut <code>⌘ Shift G</code></li>
<li>Paste the following to navigate to the proper folder: <code>~&#47;Library&#47;Containers&#47;com.apple.Safari&#47;Data&#47;Library&#47;Safari&#47;AppExtensions</code></li>
<li>Open the <code>Extensions.plist</code> in your favourite text editor (I’m a big fan of Panic&#8217;s Nova)</li>
<li>Below each extensions <code>&#60;dict&#62;</code> tag, add the following: <code>&#60;key&#62;Enabled&#60;&#47;key&#62;&#60;true&#47;&#62;</code></li>
<li>Save the file and relaunch Safari</li>
</ul>

<p>Reference of what it should look like (AdBlock for this example):</p>

<pre><code>&#60;key&#62;org.adblockplus...&#60;&#47;key&#62;
    &#60;dict&#62;
        &#60;key&#62;AddedDate&#60;&#47;key&#62;
        &#60;date&#62;2021-09-23T14:00:47Z&#60;&#47;date&#62;
        &#60;key&#62;Enabled&#60;&#47;key&#62;
        &#60;true&#47;&#62;
    &#60;key&#62;WebsiteAccess&#60;&#47;key&#62;
    &#60;dict&#62;
        &#60;key&#62;Allowed Domains&#60;&#47;key&#62;
        &#60;array&#47;&#62;
        &#60;key&#62;Has Injected Content&#60;&#47;key&#62;
        &#60;true&#47;&#62;
        &#60;key&#62;Level&#60;&#47;key&#62;
        &#60;string&#62;All&#60;&#47;string&#62;
        &#60;&#47;dict&#62;
    &#60;&#47;dict&#62;
</code></pre>

<p>After following those simple steps you should have working extensions in Safari. Have fun on your old, &#8220;unsupported&#8221; Apple devices!</p>
