Earlier today, Apple officially released a security patch for macOS High Sierra. That software was specifically meant to address a security flaw related to root access on a Mac.

That software update also included a fix for file sharing issues still plaguing some Macs out there in the wild. Following the update, Apple has released a support document that outlines a fix for the file sharing issue. You’ll have to be at least a little familiar with the Terminal app that’s on your Mac to get it done.

“If you experience issues with authenticating or connecting to file shares on your Mac after you install Security Update 2017-001 for macOS High Sierra 10.13.1, follow these steps to repair file sharing.”

Here are the steps that Apple has listed:

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

As it stands right now, the fix appears to patch macOS High Sierra 10.13.1. However, it does not appear to fix the issue in macOS High Sierra 10.13.2, which Apple is currently in the process of beta testing, with a public launch expected sometime in the month of December. By the time that Apple does publicly launch the software, this issue will likely be fixed in that software as well.

Did you run into any file sharing issues in macOS 10.13.1 after installing the security update today? If so, let us know if this fix patches it up for you.
