Question? Where do I find “Clear Cache”


Are these three options below identical

From Safari Dropdown > Clear History

From >Safari > History Drop Down > Clear History

From Safari >Preferences > Privacy > Button > Remove All Website Data

Sorry I don't know if the first two are identical but I do know that the 'Remove all website data' button is different to clearing history. Do you have a more details button next to it?


Website data is cookies and 'local storage' databases.

Cookies are used to keep track of your activity or help you stay logged in to sites etc. They have a bad reputation, but there are valid uses for them. Local Storage is used by some sites to cache data, for example online document editors may save edits in your browser storage and then sync edits back to the site when the internet is available.

Did you read my post?


History is the addresses of sites you have visited, it is used when you search (search suggestions can refer to pages in your history).

Website data is explained in my last post unless I was unclear?

Cache in this context is a local copy of 'stuff from the internet'.


Many websites reuse things like images, style sheets, scripts and other assets (webpages are made up of lots of files types). Web browsers keep a local copy of these files to avoid downloading them for every page request. It makes browsing faster & more efficient (less data is transferred this way).


This means when you visit a site like Apple.com Safari grabs the logo and keeps it around incase you visit another page that is using the same file.

The main issue with cache's is that the server may change the file & your browser could use an out of date copy, clearing the cache will cause Safari to fetch the new version & cache it again.


OS X has other caches, but it generally manages these fine on it's own.
