How do I determine OSX Hardware type?

Using Java 6 in OSX, how can I determine if the current hardware is a Desktop or a Laptop? I was looking through System.getProperty(), but didn't find anything definitive.

You can query ioreg for the model via ProcessBuilder, as shown here.

Addendum: Similar information may be obtained from the output of system_profiler.

You can use standard Unix tools to discover some of the information you may need to make this determination.

Here is an example from my machine:

>[jhr@Blackintosh] system_profiler SPHardwareDataType

Hardware Overview:

  Model Name: Mac Pro
  Model Identifier: MacPro3,1
  Processor Name: Quad-Core Intel Xeon
  Processor Speed: 2.33 GHz
  Number of Processors: 1
  Total Number of Cores: 4
  L2 Cache: 4 MB
  Memory: 8 GB
  Bus Speed: 1.33 GHz
  Boot ROM Version: MP31.006C.B05
  SMC Version (system): 1.30f3
  Serial Number (system): G8819IY0XYK
  Hardware UUID: 8F6CD4F7-BA8F-5564-84DA-55A5AC59D42E

The Model Identifier: tells you exactly what model of hardware is being used.

It would be a simple exercise to exec() the command system_profiler SPHardwareDataType and parse the response line by line and get what you need.

system_profiler without any arguments gives you ever detail about the machine and the OS.

This info is not readily available to Java. You'll probably have to call to a native library to obtain that information. Here's a question that deals with that problem: Getting the Machine Type and other Hardware details through Cocoa API
