Security Update 2017-001 Breaks File Sharing (But a Fix Is Already Out)

Better to close this security hole and inadvertently break file sharing than to leave the hole open, but this is why bug fixes aren’t usually released in under a day.

Update: Nice — an official fix for this is already out:

  1. Open the Terminal app, which is in the Utilities folder of your Applications folder.
  2. Type sudo /usr/libexec/configureLocalKDC and press Return.
