I have a MacBook, and my video viewport is blank

For iMac, MacBook and MacBook Pro, iGotchr! blends in well with the built-in iSight camera on your computer.

For most first time users on Mac OSX, you need to setup iSight to be selected in the settings.

To do this, you will:

1. Hover over the blank video area
2. Hold the "control" button and click on your mouse
3. You will see the context menu, select "Settings..."
4. Click on the "Video" tab and select "USB Video Class Video" from the dropdown menu.
5. You should see your iSight is now enabled.
