To all students, faculty, and staff using Mac computers,

This week (November 27, 2017), a major vulnerability was found in the latest version of macOS ("High Sierra").  It's a bug that would allow someone to "hack" your computer and take complete control, possibly even from another computer over the network.

Apple has already released a patch for this.  It will install automatically as long as updates are turned on and you're connected to the internet. All Mac users should make sure that this feature is enabled.  The instructions are below.  If you have any concerns or would like help with this, please stop by ITS with your computer and we would be happy to assist you.

  1. Click the Apple Menu in the top left corner of your screen
  2. Select "System Preferences"
  3. Select "App Store"
  4. Make sure that the following two boxes are checked:
    1. "Automatically check for updates"
    2. "Install system data files and security updates"

If these boxes are grayed out, then first click the padlock in the lower left corner of the box and type in your password to make changes.

If you have questions or concerns, please call IT Services at (208) 467-8111 or create a ticket at
