I am developing a app for Mac App Store in which I need to clear recent histories of application for this I do remove a particular Key in a plist file. I do this with the help of "defaults delete" command. It works fine for me but after sandboxing my app is failed to do so.
Let me tell you the case I am removing a key named "FXRecentFolders" from "~/Library/Preferences/com.apple.finder.plist" file using "defaults delete" command. It give me the following error in sandboxing app
"sh: /bin/ps: Operation not permitted
2015-06-12 15:35:46.798 defaults[2801:101247]
Domain (com.apple.finder) not found.
Defaults have not been changed.
killall: warning: kill -TERM 256: Operation not permitted"
Due to this error my project is going too late.
