OKIEHABU NetBarrier X4 does a very good job of notifying the user each time an app tries to call home. It can be set to generate a popup advisory complete with any OSX audio tone. SyndicationManager, an app running in the OSX 10.4 System folder, is a repeat offender; I finally got so tired of seeing popups alerting me to SM's frequent attempts to transmit packets OUT, and was being DENIED, etc., that I found its main repository in Macintosh HD/System/Library/PrivateFrameworks/Syndication.Framework and enclosed the SyndicationAgent app in a .zip-locked folder. I then had to delete the un-zipped original; but no more problems since. Dashboardadvisoryd is also a bit troublesome, so I did the same thing there, since I never use Dashboard anyway. Peculiarly, Mac Mail now has a little glitch where dragging an item from one place to another in the body of a message does not remove that item from its former position. One must be extra careful with editing because of this. As well, web pages now complete loading with the "X" remaining in the toolbar reload space, as opposed to displaying the reload icon. Clicking the X, however, bumps the process to completion so that the page can be reloaded, such as when js is required to view content. Another troublesome thing is the question of precisely what function port 47807 serves? Users who run a port scan (in Network Utility) on 127.0.0.1 will discover that P: 47807 is open. In Terminal, running netstat -an will reveal that 127.0.0.1 is listening on 47807. Listening for what? Does LittleSnitch know?
