Metadata files should not be written on Network Volumes

When you access directories with Apple Finder, hidden meta information will be written in a file named .DS_Store (Desktop Service Store). The meta information contains individual view settings for every folder and maybe sensitive information. Turn off the creation off meta data on network stores.

How to fix it

macOS 10.11 – 14

  1. Open terminal.app
  2. Enter and press return:
    defaults write com.apple.desktopservices DSDontWriteNetworkStores -bool true
  3. Log off and log on or restart your Mac
