OS X Mavericks 10.9.5: Apple Safari 9.1.1

We have identified a technical issue with autofill and overwriting populated form fields on Mac computers running OS X Mavericks 10.9.5 with Apple Safari 9.1.1. To resolve this problem, we strongly recommend updating your OS X to the latest version. You can download the latest OS X from the link provided below,

If you prefer to remain using your current OS X, we recommend using an alternative web browser such as Mozilla Firefox (https://www.mozilla.org) or Google Chrome (https://www.google.com/chrome) as they do not have the same technical issue with autofill and overwriting populated form fields.
