I moved from 10.6 to 10.8 with the recent purchase of a MacBook Air and Safari doesn't seem to be keeping track of my pages visited. The scenario is as follows: -Open new window in Safari -Using top search bar (mine is set to Google), search for weather -Click on weather.com, page back. Click on accuweather, page back. Click on weather.gov, page back. -Quit Safari -Reopen Safari. Search again for weather. -Notice not all links have switched from "blue" (unread) to "purple" (read). Replicating this on my MBP with 10.6 all of the links I've clicked on are purple. Apple Support has no idea what is causing this. I created a guest account on the Air and was able to recreate it. Any ideas?
