I recently updated to Mavericks. No real problems until this morning. I was unable to log into either my bank's website or to TurboTax. In both instances, I received an error message indicating that my browser was incompatible with the websites. In fact, TurboTax's website suggested that I "upgrade" my browser to Safari for Mountain Lion! Is anyone else having problems with the new Safari 7.0 and secure websites, or other websites in general?
