How To Turn Off Safari Option To Open “Safe” Files Automatically
May 02, 2011 (edited since original posting)
Turning off the Safari option to open “safe” files automatically is generally considered a good security practice. To do this on a single machine, simply visit the Safari preferences and uncheck the box “Open ‘safe’ files after downloading” at the bottom of the “General” options.
It turns out that deploying this change to a large number of managed Macs is quite simple as well. The following terminal command can be used to “uncheck” the box en masse using Apple Remote Desktop (ARD) and the “Send Unix Command.”
defaults write com.apple.Safari AutoOpenSafeDownloads -boolean No
