Mac OS X Copy the NCIDpop application to your hard drive. Double-click to launch it. There will be no visual indication, but you can verify that it is running by looking for "NCIDpop" in Activity Monitor. NCIDpop will automatically quit when you log out or shut down your Mac. To launch NCIDpop automatically when you log in to Mac OS X, add it to the Accounts > Login Items panel in System Preferences. To change the NCID server, hold down the Command key while opening the NCIDpop application. To view your call history, open NCIDpop again (after it is running). Running a NCID Server Before you can use NCIDpop, you will need to be running a Network Caller ID server. NCIDpop is designed for use with ncidd. When NCIDpop first starts, you will need to enter the hostname or IP address of the server running ncidd. If the server is running on the local computer (currently possible only with Mac OS X), enter "localhost". If you make a mistake, see the directions above to change the NCIDpop server setting for your operating system. If you are running ncidd on a non-default port (i.e., not 3333), enter the server name followed by a colon and the port number, e.g., callerid.domain.name:1234.
