Mac High Sierra Users Should Install Recent Security Update

Wednesday, November 29, 2017

On Tuesday, Nov. 28, Apple announced a Mac OS High Sierra vulnerability. This issue affects versions 10.13 and 10.13.1. 

The following day Apple released a permanent fix for the issue. You should install that software update via the Apple App Store (under your Mac Apple menu) as soon as possible.

Note: Apple’s instructions state, “If you require the root user account on your Mac, you will need to re-enable the root user and change the root user’s password after this update.” Root access is an advanced feature that should not be enabled unless you fully understand its use and risks. A good general rule is that if you don’t know if you need root access, it is most likely that you don’t. For more information, contact your local IT support.

Incidents like these are good reminders to maintain a “Stand up, Lock Up” policy and never leave your computer unattended without signing out or locking your screen.

If you have any question, please contact your local IT support.
