Okay.... Now I feel miserable that I choose to stay in S. Korea for Summer. I'm on vacation, out of States apparently, and now all my devices, including Xbox, apple TV, and some of applications I run, are having serious problem with this "LOCATION." I managed to solve the problem, by using proxy server in US. But the real problem is, other than my Macbook Pro 13", it somehow cannot share the proxy settings. I did set everything in the system preference. Connection-wifi-advanced, proxy : all ok. share-internet sharing-via ethernet: all ok. But somehow it doesn't share the proxy settings. Any insights? I would really appreciate it.
