To complete the installation of iRAPP from a downloaded ZIP package, e.g iRAPP_Setup.zip:

1. Unpack the ZIP using the following command:
   unzip iRAPP_Setup.zip
2. The DMG package name has a format like iRAPP_Server_Mac_Setup_XXXXXX.dmg, where XXXXXX is the version,
   e.g iRAPP_Server_Mac_Setup_175314.dmg. Mount DMG using the command below.
   
   By default, DMG will be mounted to /Volumes/iRAPP.
   hdiutil attach iRAPP_Server_Mac_Setup_XXXXXX.dmg
3. Install iRAPP using one of the following commands;
   choose the correct command according to your general OS version:
   
   For OS X 10.6: sudo "/Volumes/iRAPP/iRAPP Setup.app/Contents/Resources/rapsetup.src/1060/rapsetup" install
   For OS X 10.7: sudo "/Volumes/iRAPP/iRAPP Setup.app/Contents/Resources/rapsetup.src/1070/rapsetup" install
4. Store the iRAPP service state using the following command:
   sudo rapservice start -w
5. Check your current license using the following command:
   sudo rapservice liccmd check -i
6. If your current license is not valid, you can load and activate another license with this command:
   sudo rapservice liccmd load -i -f "FULL_NAME_OF_LICENSE_FILE"
7. If you would like to configure HTTP proxy for use by license engine,
   please use "help" command ( sudo rapservice liccmd help ) for details about the commands you need and then reconfigure the engine and repeat steps 5 and 6.
8. Reboot computer with the command:
   sudo reboot

NOTE: Command-line setup does not automatically check the current OS version.
Please be sure to choose the correct OS version, as iRAPP can experience unexpected problems if the correct version is not used.

sudo /System/Library/CoreServices/rapserver.app/Contents/Setup/rapsetup uninstall.
