Which Mac are you using (technical specs), and which OS? What about your internet connection? Do you use a regular cable instead of wireless? It's hard to help you without knowing more Skaoutar.... You can give important informations using the "options" button at the upper right corner of your question, "Edit'" to add text. Thank you.
