User Profile

[Mac OS] Hi, I am looking for a way to maintain a preference for my app with below requirements: The preference should be editable only by an administrator ( or an user of admin group) everyone should be able to read (only) the preference, so that my app can fetch it during app launch for all users Q) Is it possible to make a certain key with above restrictions in a .plist file? Q) Is there any better way to achieve the same on mac os.

I have created two applications both calls EnableSecureEventInput api when launched to enable secure input (keyloggers should not capture keystrokes). But when one of these application calls DisableSecureEventInput it is disabled system wide and the other application also lost the secure input though it had called the enable api. isn't this buggy? or am i missing something here? I tried to look for the api's behaviour online but could not find any, except the technical note: https://developer.apple.com/library/archive/technotes/tn2150/_index.html#//apple_ref/doc/uid/DTS10004249 which is too old not having enough details.
