I updated my Safari from 6.1.6. to the latest version. It still shows that I'm using Safari 6.1.6. I tried rebooting. Still old version. Is there something else I should be doing?

Hmmm…thanks. That's not good news, since I'm using Weebly for my websites, and they are not supporting 6.1.6 any longer. I'll have to use a different browser I guess. Does this mean I'd have to change my operating system to update Safari? Is this (a) doable, and (b) a good or bad idea??
