The AppStream 2.0 macOS client supports two connection modes: Classic mode and Desktop view. Your administrator will set up the connection mode for you.
Classic mode
When you use classic application mode, you work with remote streaming applications in the AppStream 2.0 session window. If your administrator has made more than one application available to you, you can open multiple applications during your session. All applications that you open are displayed in the same AppStream 2.0 session window.
When you connect to AppStream 2.0 in classic mode, the AppStream 2.0 Application Launcher window opens and displays the list of applications that are available for you to stream. When you open a streaming application in this mode, the Application Launcher window closes, and the application opens in the AppStream 2.0 session window.
Desktop view
When you connect to AppStream 2.0 and choose Desktop view, AppStream 2.0 provides a standard Windows desktop view for your streaming session. The icons of applications that are available for you to stream appear on the Windows desktop. In addition, the AppStream 2.0 toolbar, which enables you to configure settings for your streaming session, appears in the top left area of your streaming session window.
