IMPORTANT: Mac Desktops will require Java SE 6. This is included in OS/X 10.6 (Snow Leopard) and higher. Older Intel based Macs might be able to use a third party Java runtime but this has not been tested. PowerPCbased Macs will not be able to run the APPX Desktop Client at all, since Apple does not provide Java SE 6 for this platform.
