Apple’s quick fix for a major security flaw in macOS High Sierra has resulted in another issue for some users. The update introduces yet another bug that breaks file sharing, but Apple has published instructions on how to repair it.
Remember when Apple software was as sturdy as a tank? That’s not the case anymore. With every update, it seems there are new bugs for users to contend with. Some of those are minor; others are surprisingly catastrophic.
A security flaw discovered in High Sierra this week falls into the latter category. It left every user open to attack by allowing anyone to gain administrator access on their Mac without a username or password. Apple fixed it quickly, but introduced a new problem.
File sharing is broken in High Sierra
Some users are now discovering that file sharing no longer works. Apple has published step-by-step instructions on how to fix the problem, but you’ll have to do it manually:
- Open the Terminal app, which is in the Utilities folder of your Applications folder.
- Type
sudo /usr/libexec/configureLocalKDCand press Return. - Enter your administrator password and press Return.
- Quit the Terminal app.
It’s great that Apple issued this support document soon after recognizing another issue in High Sierra. But it shouldn’t be up to users to fix problems with its software. What happened to “it just works”?
Not all users are experiencing the file sharing problem, so we recommend you try the feature before following the steps to fix it.
Hopefully we’ll soon see another update that eliminates this issue automatically. But who knows what kind of problems that will bring.
