We're setting up a Sophos UTM, but we are finding with the Macs in our organisation, even after we install the UTM's root CA certificate into its System keychain, the Apple Software Update does not work. It fails with the error:
NSURLErrorDomain error -1012
This happens whether we go in through the GUI (App Store) or on the command line with the softwareupdate utility.
After installing the certificate, the App Store itself works, it's just Software Update that doesn't.
Does anyone have any suggestions?
Thanks,
