I've recently just purchased the MacBook. It was working fine until sites such as Google, Ask, and Yahoo stopped working. It says that it can't connect to the server for some reason. However, the sites work on my home computer, iPod Touch and pretty much everything else except this MacBook. I have both Safari and Mozilla and they both don't log on to search engines. Weird. Anybody can please help me fix this problem? I would really appreciate it. I have another question. If I were to reboot the whole system, how would I be able to do that? Thank you very much!
