I have been using Safari 6 for a while now and for the most part think it’s a good improvement on the previous version.
I was doing a little troubleshooting on my mac and noticed that the “Reset Cache” option was’nt where it used to be under the Safari option. It seems that Apple have now moved the ability to reset cache and consequently made it harder to find.
In order to now reset cache, you must go to the Safari > Preferences menu, choose the advanced tab and then check the box to “Show Develop menu in menu bar”.
Now, underneath Develop, you will have the option to “Empty Caches”.
