This is a really odd situation. I have one client machine that cannot download a particular Apple update. This is the error message that comes up:
softwareupdate -d -a
Software Update Tool
Finding available software
Error downloading Security Update 2017-002: The Internet connection appears to be offline.
Done.
Error downloading updates.
Here are two things that make this situation weird:
Software Update Tool
Finding available software
Error downloading Security Update 2017-002: The Internet connection appears to be offline.
Done.
Error downloading updates.
- The machine can contact any random website, including Apple’s.
- The machine eventually could even download and install the Safari update from the Apple servers.
