Uh-oh,Eric Falk Apple.

After fixing that embarrassing macOS High Sierra bug that let anyone create a root account on a Mac without a root password, Apple introduced a new bug, albeit one far more benign.

The security update 2017-001, described here, indeed fixed the nasty vulnerability in High Sierra 10.13 and 10.13.1, but it completely messed up file sharing for some users.

Luckily, the new bug doesn't require a patch. Instead, users have to manually type out a command in the Terminal app. The steps, per Apple's support page, 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. 

While this latest bug likely won't cause much damage, it's more evidence that High Sierra needed more testing before release. In September, a hacker discovered a bug that lets an attacker steal one's password, as long as they are able to install an unsigned app on the system. And in October, Apple fixed that and another serious security flaw, which caused the user's password to be revealed in plain text in some scenarios.

After the discovery of this latest security flaw, Apple apologized to customers, saying the company has "stumbled with this release of macOS." The company also said that it's auditing its "development processes to help prevent this from happening again."
