Safari 5.1 (OS X Lion): Empty the cache
As you open webpages, Safari saves the pages on your computer in a temporary location called the “cache.” If you return to a webpage later, Safari can retrieve the webpage from the cache faster than getting it from the web, so the cache is a good time-saving device for pages you return to repeatedly.
If the content on a webpage seems outdated, you may want to empty the cache to make Safari retrieve the latest version of the page. If you think a webpage is not opening properly, emptying the cache may help.
Empty the cache
- Open Safari if it is not already open.
- Choose Safari > Empty Cache, and then click Empty.
