the "About This Mac" won't show, and the "More Info..." won't show...

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.

System Profiler.app (or System Information.app 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 Profiler.app from your Mac OS X DVD).

system_profiler is the command-line equivalent (or System Profiler.app might be the GUI application to this CLI program). You need to enter system_profiler at a command prompt in Terminal.app. 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).

    Unfortunately the CPU information given by System Profiler isn't very useful. I'm looking at a "2.7 GHz Intel Core i5" and a "2 GHz Intel Core i5"; it's only when you know that the former is an i5-5257U and the latter is an i5-6360U that you know that the "2 GHz" CPU is actually faster than the "2.7 GHz" CPU.

You can find the full model number with the following command (source):

sysctl -n machdep.cpu.brand_string

This will return something like:

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

    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 Nov 22, 2014 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.

Adding to @AlexT's answer,

open http://www.google.com/?q=$(sysctl -n machdep.cpu.brand_string | awk '{FS=" " ; print $2 "+" $3 "+" $4}')+site:ark.intel.com

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