How to delete internet cookies and cache files.

Safari->"Empty Cache..." will get rid of the cached files (which take up the most room).

Safari->Preferences...->Security->"Show Cookies"->"Remove All" will clear out your cookies.

History->"Clear History" clears your history.

Or you can just enable Safari->Private Browsing each time, and those things will never be saved.

I'm note sure if iClean will or won't run (it probably will, but no promises), but these are simple steps - no real need for a separate app to do them.

Also, Safari->"Reset Safari..." will remove everything - maybe even bookmarks (not sure) so I'm afraid to use that option personally.

 

In Safari you can click clear history on the bottom of the history menu. I don't know how to do the rest manually, but you could probably install iClean on your macbook.
