Apple High Sierra Exploit, Manual Partial Fixes

Apple High Sierra Exploit, Manual Partial Fixes

A very serious exploit for Apple systems running the High Sierra OS has come to light.  You can read more about it here:

For a short-term fix Apple suggested this:

In working on a long-term fix, Apple created another issue in which file shares/sharing is broken.  You can read more about that one here:

https://www.macrumors.com/2017/11/29/apple-macos-high-sierra-file-sharing-fix/

While a fix for that is pending, the manual steps to fix it are as follows:

1. Open the Terminal app, which is in the Utilities folder of your Applications folder.
2. Type sudo /usr/libexec/configureLocalKDC and press Return.
3. Enter your administrator password and press Return.
4. Quit the Terminal app.

If you need help with either of these issues or their subsequent patches/fixes, please give us a call at ESG!
