I'm developing a feature of a file manager APP that can deny user's access to some specific files. I don't want to use any "chmod" related tech coz user can always overwrite it with admin. During my research, I found out it is possible to use OS X kext "apple.com.fileutil" to deny user's access to files. So I'm asking does anyone has any infomation about "apple.com.fileutil" ? API, callback, anything will be helpful. Thank you very much!
I’ve not seen the identifier
apple.com.fileutilcom.apple.fileutilfileutil.apple.comShare and Enjoy

let myEmail = "eskimo" + "1" + "@apple.com"yes, I found out "oneDrive" of Microsoft use extended attributes(xattr) to control user access permission,
they seems to set one key/value pair "com.apple.fileUtil.PlaceholderData"/someData to xattr, but I can't know the someData structure Or what principle does it follow?
could you help me? thanks.

Thanks for replying. You're right I mistyped the identifier, it is "com.apple.fileutil". I found it in the kext list with command "kextstat". I believe I can use this kext to restrict user's access to some files, but I don't know how. Is there any way to interact with this kext?
As far as I know that KEXT and its associated extended attributes are all private.
