====== Pointing A Mac At A Software Update Server ======

Run Terminal while logged in as a machine administrator and at the terminal enter the command

''defaults write com.apple.SoftwareUpdate CatalogURL URL''

Where URL is the URL of the Software Update server. For example:

%%http://su.domain_name.com:8088/%%

So in our case :

''defaults write com.apple.SoftwareUpdate CatalogURL %%http://sus.us.com:8088/%%
''
