 The [SfRichTextEditor](https://help.syncfusion.com/cr/maui/Syncfusion.Maui.RichTextEditor.SfRichTextEditor.html) supports inserting images (JPEG, PNG) into the content area. Images can be added by the end-user through the toolbar or programmatically from various sources like a stream or a file path.
 
+**Enable File Access Permission**
+
+On MacCatalyst devices, you need to enable file access by adding the required permission in the platform specific "Entitlements.plist" file, as illustrated in the following code snippet.
+
+{% tabs %}
+{% highlight C# tabtitle="Entitlements.plist" %}
+
+<key>com.apple.security.files.user-selected.read-write</key>
+<true/>
+
+{% endhighlight %}
+{% endtabs %}

 ## Insert an image from the gallery
 
 When the user taps the Image toolbar button, the [ImageRequested](https://help.syncfusion.com/cr/maui/Syncfusion.Maui.RichTextEditor.SfRichTextEditor.html#Syncfusion_Maui_RichTextEditor_SfRichTextEditor_ImageRequested) event is triggered. You can handle this event to open the device's media gallery and insert the selected image. .NET MAUI provides a built-in `IsHandled` API to select photos from the gallery.
