+Debugging on macOS
+==================
+
+Debugging Godot editor
+----------------------
+
+Attaching a debugger to the signed macOS process requires the "com.apple.security.get-task-allow" entitlement, which is not enabled by default, since apps can't be notarized as long as it is enabled.
+If you want to debug an official build of the editor it should be re-signed with the proper entitlements.
+
+Create a ``editor.entitlements`` text file with the following contents:
+
+.. code-block:: xml
+
+    <?xml version="1.0" encoding="UTF-8"?>
+    <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
+    <plist version="1.0">
+        <dict>
+            <key>com.apple.security.device.audio-input</key>
+            <true/>
+            <key>com.apple.security.device.camera</key>
+            <true/>
+            <key>com.apple.security.cs.disable-library-validation</key>
+            <true/>
+            <key>com.apple.security.get-task-allow</key>
+            <true/>
+        </dict>
+    </plist>
+
+Then use the following command to re-sign the editor::
+
+    codesign -s - --deep --force --options=runtime --entitlements ./editor.entitlements ./path/to/Godot.app
+
+Debugging exported project
+--------------------------
+
+To allow debugging, select the ``codesign\debugging`` (``com.apple.security.get-task-allow``) entitlement during the export. When it is selected, notarization is not supported and should be disabled.
