The accessibility permissions are stored in a sqlite database file at /Library/Application Support/com.apple.TCC/TCC.db. Since sqlite3 is shipped by default with the later Mac OS X', use it to modify the settings. The db scheme looks like this. Sep 08, 2014 Boot into single-user mode and at the prompt enter these commands pressing RETURN after each. Mount -uw / chown root:admin / chmod 1775 / reboot. After rebooting Set the following Directory permissions. You can paste these lines or enter by hand, but be careful to enter them correctly. Administrative users: Although a complete discussion of the special permissions that a user with administrator permissions has on a Mac running Mac OS X is very complex, note two important things: The first user created (usually when you install OS X for the first time) is automatically granted administrator (Admin) powers. Mar 15, 2017 By default, Mac apps are self-contained, and can’t change the way you interact with the system or other applications. This is a very good thing. It prevents sketchy things from happening, like games you’ve downloaded logging your keystrokes or malware clicking buttons in your browser.
When you first create a share point, Mac OS X Lion Server assigns it standard POSIX permissions for Owner, Group, and Others. You can change the owner and group, change the permissions for all three entities, and add users. Standard POSIX permissions are easier to set than ACLs and may be all that you need.
For share points shared with AFP and/or SMB, you can also add permissions with an access control list (ACL) for a finer degree of access control. An ACL is the server’s list of all permissions for all users and groups and for a share point. You add names of users and groups to the list and then use pop-up menus to assign permissions.
ACLs are more complicated than POSIX permissions because they give you up to 17 choices: 13 permissions grouped by type, as well as 4 types of inheritance.
With almost 100,000 possible combinations of ACL permissions, it’s best to set permissions for groups and add user permissions only for exceptions.
These ACL permissions settings are well hidden in the Server app. Here’s how to access them in the Server app:
1Click the name of your server.
You will find it in the sidebar under Hardware.
2Click the Storage tab.
Browse for and select a shared folder.
3Click the gear icon and select Edit Permissions from the pop-up menu.
A list of users and groups appears.
4If you want to add a user or group, click the Add (+) button.
Type the name of an existing user or group.
5To configure permissions, click the triangle to the left of the user or group name.
This exposes the first level of ACL permissions. You have four choices: Administration, Read, Write, and Inheritance. You can make choices here. A hyphen [–] in a check box means that some, but not all, of the subordinate items for that category are selected. Selecting or deselecting a check box selects or deselects all of the subordinate items.

This will let you go even deeper into ACL permissions. Make any changes that you need and click ok when done.

An application is a type of file that you can share. If you do, set permissions so that very few people can change permissions for shared applications. In the ACLs, under Administration, few people should have the Change Permissions and Change Owner permissions. Malware such as viruses often targets permissions in applications.
