Yesterday, researchers made a discovery that any Mac running High Sierra can be unlocked by anyone and lets them get Root access. Apple was quick to release an update for macOS to address the problem. And doing so, created another issue related to file sharing.
In its support document published today, Apple explains that some users are experiencing issues authenticating and connecting when it comes to file shares. If the users are facing such issues on their Mac after installing Security Update for macOS High Sierra 10.13.1, then they need to follow the steps below.
- Open the Terminal app, which is in the Utilities folder of Applications folder.
- Type sudo /usr/libexec/configureLocalKDC and press Return.
- Enter your administrator password and press Return.
- Quit the Terminal app.
As 9to5Mac points out, this bug is a small price to pay for Apple’s quick fix, and it shouldn’t be a reason to avoid installing today’s update either, especially the above given fix.
Apple, on the other hand has apologized for the security loophole and highly recommends intalling the update immediately, which requires no restart.
“Security is a top priority for every Apple product, and regrettably we stumbled with this release of macOS.”
“When our security engineers became aware of the issue Tuesday afternoon, we immediately began working on an update that closes the security hole. This morning, as of 8 a.m., the update is available for download, and starting later today it will be automatically installed on all systems running the latest version (10.13.1) of macOS High Sierra.”
