Get CPU Info via Command Line in Mac OS X

Jul 15, 2011 - 1 Comment

An example of a computer processor chip Ever wondered specifically what processor was being used on a Mac, including processor type and CPU speed? It’s actually quite easy to retrieve CPU information from the command line in Mac OS X, though the commands to use may be unfamiliar to many. We’ll show two ways to grab a Macs CPU details from the command line of OS X.

Finding Mac Processor Details & CPU Speed with sysctl

First we’ll use sysctl because it give us everything on one easy to read line:

sysctl -n machdep.cpu.brand_string

The example output may look like any of the following:

% sysctl -n machdep.cpu.brand_string
Intel(R) Core(TM) i5-5257U CPU @ 2.70GHz

This is basically in the following format: Chip Brand – Processor Type and Chip Model – CPU Speed

Intel(R) Core(TM)2 Duo CPU E8600 @ 2.40GHz

That detailed output of sysctl is advantageous because it reports back the chip model as well.

Get CPU Processor Details of a Mac with system_profiler

On the other hand, if you don’t want the model number and simply want processor name, speed, and the number of processors, you can use grep with system_profiler:

system_profiler | grep Processor

Processor Name: Intel Core 2 Duo
Processor Speed: 2.4 GHz
Number of Processors: 1

There are probably other methods as well, but these two are detailed and give you the information you need.

For the record, and for more average Mac users, there is a much easier way to get this information, just go to “About This Mac” under the  Apple menu.
