Question: No Access/Internet to Apple Apps
After downloading High Sierra, I have been experiencing numerous problems. For instance, although my computer is connected to the internet (as evidenced by the WIFI signal indication as well as connectivity to certain browsers), various applications seem to not be connecting to the internet. Safari, for instance, only works intermittently, while apps like "App Store" and Itunes have no connectivity at all. I have tried to update my computer; however, given that the "App Store" does not recognize the internet internet connection - like many other apps - I am unable to update the machine. Any advice would be immensely appreciated.
MacBook Pro, macOS High Sierra (10.13.1)
