A serious flaw in Apple’s macOS High Sierra software was discovered Tuesday, and Apple released a patch today to fix it. The UC Davis Information Security Office and other security experts are advising Mac users to install the patch immediately.
The flaw can allow someone to log in to a computer without using a password. This article has more information.
If you have an Apple computer with High Sierra and manage it yourself, please install the patch. If your machine is managed by someone else, they will likely install the patch for you. If you have questions, please contact your department’s tech support or the IT Express Service Desk.
