WHAT HAPPENED?

Apple released Security Updates for Safari, iOS and OS X Mavericks, Yosemite, and El Capitan to address multiple vulnerabilities.

Advanced Users: For a complete description of the security enhancement and affected software refer to:

• About the Security Content of Safari 9.01 at https://support.apple.com/en-us/HT205377.
• About the Security Content of iOS 9.1 at https://support.apple.com/en-us/HT205370.
• About the Security Content of OS X El Capitan v10.11 at https://support.apple.com/en-us/HT205375.

IT does not recommend upgrading to OS X El Capitan until further testing can be done as the new operating system is incompatible with nearly all of UCSF’s security/reporting software (Symantec Endpoint Protection, DDPE, and BigFix).

- OS X Yosemite v10.10.5

HOW DO I PROTECT MY COMPUTER?

Update your software

• Safari

1. If IT Field Services or you have other IT support, no action on your part is required.
2. If you do not have IT support, updates may be obtained from Mac App Store.

• iOS 9.1

Updates may be obtained through iTunes only.

Installation note:

Since the automatic update process may take up to a week depending on the day that iTunes checks for updates, Apple recommends you manually obtain the update via the "Check for Update" button within iTunes. After doing this, the update can be applied when your iPhone is docked to your computer.
