How to Clear Your Cache on Safari

This one is for Mac users only. You can delete your cache along with all your other browsing data (history, cookies, etc) by going to the Safari menu > "Clear History and Website Data" to prompt a pop-up similar to the other methods (except with the ability to delete different types of browsing data).

However, there is a way to delete just your cache if you are willing to take a few extra steps:

Step one: Enable to the secret "Develop" menu by going to Safari > Preferences > Advanced [tab] > click the "Show Develop menu in the menu bar" box at the bottom. This will enable the new Develop pull-down menu at the top of your browser window.

Step two: Click on the Develop menu and scroll down to "Empty Caches" (or alternatively, press Option-Apple key-E after the Develop menu has been enabled.)
