+With `frameit` 2.0 is possible to also frame Mac OS X Applications. You have to provide the following:
+
+- The `offset` information so `frameit` knows where to put your screenshots
+- A path to a `background`, which should contain both the background and the Mac
+- `titleHeight`: The height in px that should be used for the title
+
+##### Example
+```json
+{
+  "default": {
+    "title": {
+      "color": "#545454"
+    },
+    "background": "Mac.jpg",
+    "offset": {
+      "offset": "+676+479",
+      "titleHeight": 320
+    }
+  },
+  "data": [
+    {
+      "filter": "Brainstorming",
+      "keyword": {
+        "color": "#d21559"
+      }
+    }
