Update Safari on your Mac to protect against Spectre bug

All University Mac users are strongly advised to update to the newest version of Apple’s Safari web browser in order to protect against the impact of the Spectre bug recently announced in the news. The update will help to ensure that Macs have the latest security features, and remain compatible with other University systems.

To Update Safari

  1. Go to Mac Self Service
  2. Under Categories, click on OS Updates*
  3. An icon saying either Safari v11.0.3 Update for OS X El Capitan or Safari v11.0.3 Update for macOS Sierra should appear*
  4. Click on Install (this may take a while to complete)
  5. This install will take several minutes but no reboot is required upon completion

* Customers will see only the relevant update option for their operating system version

Safari updates will only appear if you are running the latest version of either the OS X El Capitan (10.11.6) or macOS Sierra (10.12.6) operating systems. You can check which version is running by selecting About This Mac.

If your macOS version is OS X Yosemite or earlier, please follow the instructions available here to upgrade to macOS Sierra (10.12.6).

Manually Assured Users

It is recommended that you run all available updates for the system in the App Store, as per this advice:
