MacOS High Sierra was updated last night, with Apple solving a major security issue that allowed anyone to gain administrator access to any Mac without a password. Everything was based on a very serious error in the development of macOS High Sierra that puts the Apple company in a very embarrassing situation, because such a vulnerability should not have existed from the very beginning.
macOS High Sierra had the problem solved extremely quickly by those from Apple, in just one day, but the solution implemented by the company generated another equally annoying problem. More precisely, users who have installed the security update can no longer share files from their Macs, and Apple had to present a new solution to solve the problems of those using macOS High Sierra.
macOS High Sierra has the solution for this problem presented in a support document that the Apple company published, but of course it involves making some changes in the operating system. Below are the recommendations made by Apple for macOS High Sierra users who want to share files, but if you don't need it, you can ignore them.
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:
- 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.
