Is there a way to prevent XCode from downloading from the Internet?

I'开发者_运维百科m running XCode 3.2.2 on Mac OS X 10.6.6. My Activity Monitor shows that XCode periodically downloads from the Internet while running. Is there a way to prevent XCode from downloading from the Internet? My service provider imposes a limit on how much I can download before slowing my download to a crawl.

Chances are this is just Xcode downloading updated documentation sets - to disable this, simply go to the "Documentation" option within Xcode preferences and un-check the "Check for and install updates automatically" option.

System Preferences -> Security -> Firewall.

You should be able to add Xcode the list and make it not allow any connections.

I went to XCode->Prefereces->Downloads->Documentation and clicked the minus button to move serval items to "Trash". That deleted these huge documentation files that had added a few GB my Library/ directory. Presumably it will now still do Xcode updates, but without the bloated documentation.
