Downloaded MacOS High Sierra to my 2011 iMac. Now wifi works on some applications, but not others.

Specifically, it works perfectly fine for Chrome and all mobile devices so it doesn't seem like an issue with the wifi itself. But basically nothing else works. Not Safari, Amazon music, the App store, Apple Notes, etc. I had no isssues at all prior to the update.
