CPU Information for a MacBook Pro (Retina, 15-inch, Mid 2015)

The sysctl command can be used on a Mac OS X/macOS system to determine some machine dependent (machdep) features, such as Central Processor Unit (CPU) features. E.g., the output of sysctl machdep.cpu run on a MacBook Pro (Retina, 15-inch, Mid 2015) system with an Intel Core i7 processor is shown below:

You can restrict the information displayed to be more particular by using a parameter shown before the colon on each line. E.g.

$ sysctl machdep.cpu.brand_string
machdep.cpu.brand_string: Intel(R) Core(TM) i7-4870HQ CPU @ 2.50GHz
$ sysctl machdep.cpu.core_count
machdep.cpu.core_count: 4
$

If you just wish to have the value displayed and not the name as well, you can use the -n argument to the sysctl command.

    -n      Show only variable values, not their names.  This option is use-
             ful for setting shell variables.  For instance, to save the page-
             size in variable psize, use:

                   set psize=`sysctl -n hw.pagesize`

E.g.:

$ sysctl -n machdep.cpu.brand_string
Intel(R) Core(TM) i7-4870HQ CPU @ 2.50GHz
