"Updates for this Mac are managed externally". No they are not!!!
Today, I got a strange, never-before-seen, error message saying that updates to my Mac are managed externally. Which is not true.
Before anyone comments, I want to say that I am the original purchaser, the personal owner, the administrator, and the sole user of this computer. It is NOT externally managed. I check for updates every week or so. This is the first time I am seeking this message.
The other strange thing - which might be related to the problem - is that it says that there is no Internet connection. The internet connection is actually working fine in my web browser and other apps, so that message is wrong and is possibly the root cause of the problem. Is it possible that for some reason, the Settings app is unable to contact the Apple update servers and this is somehow causing its logic to be messed up?
My hardware and OS details are:
Is there a reason why the Setting app alone would not be able to establish an Internet connection?
