+The

+command displays information about the host system on which the command is executing.

+processor configuration data,

+and various scheduling statistics.

+There are no options.

+.It Mach kernel version:
+The version string compiled into the kernel executing on the host system.
+.Pp
+.It Processor Configuration:
+The maximum possible processors for which the kernel is configured, 
+followed by the number of physical and logical processors available.
+.Pp
+Note: on Intel architectures, physical processors are referred to as cores, and 
+logical processors are referred to as hardware threads; there may be multiple
+logical processors per core and multiple cores per processor package.
+This command does not report the number of processor packages.
+.Pp
+.It Processor type:
+The host's processor type and subtype.
+.Pp
+.It Processor active:
+A list of active processors on the host system.
+Active processors are members of a processor set and are ready to 
+dispatch threads.
+On a single processor system, the active processor, is processor 0.
+.Pp
+.It Primary memory available:
+The amount of physical memory that is configured for use on the host system.
+.Pp
+.It Default processor set:
+Displays the number of tasks currently assigned to the host processor set,
+the number of threads currently assigned to the host processor set,
+and the number of processors included in the host processor set.
+.Pp
+.It Load average:
+Measures the average number of threads in the run queue.
+.Pp
+.It Mach factor:
+A variant of the load average which measures 
+the processing resources available to a new thread.
+Mach factor is based on the number of CPUs divided by (1 + the number of runnablethreads)
+or 
+the number of CPUs minus the number of runnable threads when the number of runnable threads
+is less than the number of CPUs.
+The closer the Mach factor value is to zero, the higher the load.
+On an idle system with a fixed number of active processors, the mach factor will be equal to the number of CPUs.
