I have had this iMac for about a week now and web pages take FOREVER to load. I have done searches and found that a simple DNS fix should resolve this issue (not sure why this is the case when all the windows machines connected to the same router are screaming fast on the web). I have tried using some dns servers found on the web, but still not working. Is this something I should do on the router level? Why do macs have these issues when windows machines work just fine from the get-go?
