Proxy not recognized after mavericks updrade?
I have just upgraded my Macbook Air from OS X Lion to OS X Maverick two days ago. Everything working fine except the proxy setting in network is not picked up by any other application. As a result, I cannot connect to App Store/iTunes/iCloud. All of them shows, computer not connected to internet. Safari works fine for local addresses that do not need proxies but freezes for external sites requiring proxies. The firefox browser works for everything. If I open app store, it keeps rotating between two pop ups, one for proxy authentication and one for app store sign in. It becomes an infinite loop.
MacBook Air, OS X Mavericks (10.9)
