In OS X Yosemite v10.10.3 and later, you can execute this command in Terminal while logged in as an admin user. Replace nnn with the desired umask value, such as 027 or 002. This sets the umask for daemons that are launched in the system context. Changing this value is strongly discouraged because it might change the permissions on files used by the system software. If the permissions are too restrictive, dependent software may not work. If the permissions are too open, they may introduce security issues. For more information about setting the umask in Yosemite, see man launchctl. Show Sample Output
0sudo launchctl config system umask nnn -
