The default behaviour of Amadeus Pro is to regularly check for the availability of new versions of the program if it detects an active internet connection. This check happens weekly, but you can either change this frequency or disable it altogether in the Updates section of the preferences window. No personal information is transmitted during these checks, they consist in simply accessing this file. If you don’t trust what software companies tell you (and you would probably be wise not to take everything at face value) you are of course welcome to check that this is true by using tcpdump or your favourite TCP/IP packet sniffer.
If a new version is detected, Amadeus Pro can download the update and install it without any user intervention. The default behaviour is to ask the user for permission before starting the download, but if the Download updates automatically checkbox is checked, downloads will start automatically without warning. (It will however present a progress window through which the download can be cancelled.) Installing the download then requires Amadeus Pro to quit and relaunch itself. If your user account does not have sufficient privileges to erase the old version of Amadeus Pro and replace it by the new version, you will be asked for an administrator password.
Whenever Amadeus Pro checks for the presence of a new version of the application, it also checks for new versions of the manual. If a new version is detected, you will be given the opportunity to install it onto your system. The manuals are kept in the Application Support/Amadeus Pro subfolder of your Library folder. The reason for keeping the manual separately from the application is to save bandwidth. The manual currently exists in four languages, but an individual user is unlikely to need more than one of them. Furthermore, the manual is usually not updated between minor releases of the application.
