InformationThe Safari browser contains a feature which causes all files considered 'safe' to be automatically opened once they have finished downloading.
This feature is meant to be a benefit but having the browser automatically open files that could be malicious and downloaded by mistake is a security risk.
SolutionFollow the below steps to set Open 'safe' files after downloading to Disabled:
1. Click Safari.
2. Click Preferences.
3. Click General.
4. Uncheck the Open 'safe' files after downloading checkbox.
To configure the plist follow the below steps:
1. Open the com.apple.Safari.plist.
2. Find the token <key>AutoOpenSafeDownloads</key>
3. Ensure this token is immediately followed by <false/>
