Disable the creation of .DS_Store on SMB shares

.DS_Store files are automatically created by macOS and contain metadata of folders custom attributes. Follow the steps below to disable their creation on SMB shares.

• On your Samba server, edit your smb.conf file, add the lines below to each available share and restart the Samba service:

veto files = /._*/.DS_Store/
delete veto files = yes

• As an alternative, prevent macOS from reading .DS_Store files to improve browsing of the shared folders. Run the following command on your macOS terminal.

defaults write com.apple.desktopservices DSDontWriteNetworkStores -bool TRUE

• Last but not least, remove the pesky files from any existing folders:

find \( -name ".DS_Store" -or -name ".Trashes" -or -name "._*" -or -name ".TemporaryItems" \) -delete
