But if an app you need isn’t available from the Mac App Store, you can use DVD or CD Sharing. Click once to download and install any app on your Mac. No more boxes, no more discs, no more time-consuming installation. With the Mac App Store, getting the apps you want on your Mac has never been easier. To choose Man圜am as the audio source, open 'Options' (Main menu - Tools - Options.) and then click on the 'Audio Settings' menu item. In Skype, open 'Options' (Main menu - Tools - Options.) and then click on the 'Video Settings' menu item.
The webcam will not work with Skype on a Mac if it is not correctly installed.
