NAME
     taskgated -- task_for_pid access control daemon

SYNOPSIS
     taskgated [-s] [-t timeout] [-i pid]

DESCRIPTION
     taskgated is a system daemon that implements a policy for the task_for_pid system service.  When the kernel is asked for the task port of a
     process, and preliminary access control checks pass, it invokes this daemon (via launchd) to make the decision.

OPTIONS
     -t timeout
	      The daemon will quit after that many seconds of inactivity. It will be relaunched by launchd as needed. A timeout of zero can be
	      specified to make the daemon quit after servicing each request, but a small positive timeout is better for performance.

     -i pid   Inject the service port of taskgated into the process with the given pid, rather than relying on launchd to install it system-wide.
	      This is for testing only, and requires the launchd configuration for taskgated to be removed.

AUTHORIZATION RIGHTS
     system.privilege.taskport	Authorization right used to check access of allowed (but not safe) callers.

INFO KEYS
     SecTaskAccess  A value of "allowed" is required for any program that wants access to task ports. A value of "safe" bypasses authorization
		    checks if so configured.  Code must be signed by any system-trusted signing authority.

FILES
     /etc/authorization  to configure the authorization used.

HISTORY
     taskgated was first introduced in Mac OS 10.5 (Leopard).

     Procmod and procview support (-p) was removed in 10.11.

     Certain software updates of Mac OS 10.4 (Tiger) introduced the convention requiring membership in the procmod or procview groups to control
     task port access. Before that, any process could obtain the task port of any other process with the same user-id.
