App Store, "An error has occurred", "The operation couldn’t be completed. (NSURLErrorDomain error -1012.)"
I am encountering a strange issue with two Mac laptops while a third one does not have the issue. Essentially, when I start iTunes, it complains a newer version is available and that I should download it. When I accept, it launches the App Store (as it should). However, this step fails. When I select the "updates" tab, I get a dialog box "An error has occurred", with the message below:
The operation couldn’t be completed. (NSURLErrorDomain error -1012.)
What does this mean ? How can I get to run updates on those computers again ?
Thanks!
