So how do you clear the Safari cache? It’s really easy, so long as you don’t mind clearing out your history as well. It’s a rarity that Chrome or Firefox will trip up, due to cache. Why? Unlike other browsers, Safari doesn’t handle it well when a cache becomes too large. Although these tips won’t have you seeing magical results (with Safari downloading as quickly as either Chrome or Firefox), you will see some improvement. Even with that bit of conspiracy theory in check, there are things you can do to help Safari speed up the downloads. I am convinced this dogged speed was by design–in order to keep battery usage to a minimum. Or, in cases where I can easily copy the download URL, I’ll open up a terminal window and use the wget command for really speedy downloads.
