I've tried to update my computer software to the latest version but I keep getting this message "The Software Update Server (wd-od1.internal.waikatodiocesan.school.nz) is not responding." Can someone please help.

  • Well that isn't an Apple server. Have you installed anything that might contain malicious software?

    @IronCraftMan I'd bet it's a school update server that is down temporarily instead of malware. Could be that too...

Many schools and corporations point Macs at internal software update servers to control which updates arrive and when they get enabled.

  1. Contact the IT department or support if you have an institutional Mac. They might fix the server or point your Mac to another source for updates.
  2. You can sever that connection from the following post.

You can revert your settings by running the following Terminal command:

sudo defaults delete /Library/Preferences/com.apple.SoftwareUpdate CatalogURL

Alternatively, you can delete any profiles listed in the system preferences app. Be sure you have a backup before deleting or changing these settings. You might need to revert things if in fact the settings were needed to prevent some updates.
