this thread talks about system_profiler but it is not on this macbook with Snow Leopard:

can it be found out?

That forum topic is from 2005, there weren't even Macbooks (i.e. Mac laptops with Intel chips) back then. The current operating system was 10.4 Tiger. – Daniel Beck Nov 6 '10 at 12:04

System (or System in newer versions of OS X) is located in /Applications/Utilities/. You can get there by pressing Cmd-Shift-U in Finder.

If it's not there, someone with administrator access to your machine messed up your system. Reinstall Mac OS X (or try to use Pacifist to restore System from your Mac OS X DVD).

system_profiler is the command-line equivalent (or System might be the GUI application to this CLI program). You need to enter system_profiler at a command prompt in If you're only interested in your CPU and model, enter

system_profiler SPHardwareDataType

Output looks something like this:

Hardware Overview:

  Model Name: MacBook Pro
  Model Identifier: MacBookPro6,2
  Processor Name: Intel Core i7
  Processor Speed: 2,66 GHz
  Number Of Processors: 1
  Total Number Of Cores: 2
  L2 Cache (per core): 256 KB
  L3 Cache: 4 MB
  Memory: 4 GB
  Processor Interconnect Speed: 4.8 GT/s
  Boot ROM Version: MBP61.0057.B0C
  SMC Version (system): 1.58f16
  Serial Number (system): W80253LDAGZ
  Hardware UUID: 598781DD-929A-1337-F00D-EF19A1B625F8
  Sudden Motion Sensor:
      State: Enabled

An alternative to using the System Profiler is Mactracker, an application containing a database of all Mac models made so far. If you know your model (e.g. "Macbook Pro (15-inch, Mid 2010)" and your order number (e.g. "MC373LL/A") you can find out your processor (M 620 with 2.66GHz for the example).

You can get the full model number without installing Mactracker, using the method @AlexT answered below (and get even more data by augmenting it using rbanffy's script, also below). – nc01 Feb 25 at 12:46

You can find the full model number with the following command:

sysctl -n machdep.cpu.brand_string

This will return something like:

Intel(R) Core(TM) i7-2760QM CPU @ 2.40GHz

This is the most accurate answer – João Nunes Jul 1 '14 at 17:46
This is the right answer System information just tells you the processor brand. i7 is friggin useless! There are 4 generations of processors intel labeled i7 – Michael Brown Nov 22 '14 at 5:00
Is there a database of this info for various Mac models? Seems like for some reason Apple doesn't list this info in their sales materials. – Michael Mar 11 '15 at 5:09

Adding to @AlexT's answer,

open$(sysctl -n machdep.cpu.brand_string | awk '{FS=" " ; print $2 "+" $3 "+" $4}')

brilliant idea! – 比尔盖子 Sep 2 '15 at 12:01
Added it to for a more permanent presence. – rbanffy May 4 at 8:02
I added a bit more – Haroen Viaene Jun 27 at 12:10

I didn't find any way to check it with software, but on this site: you can find more details than system profiler provides (including cpu model)
