If your Mac is giving you fits, do not worry, you are not the first person ready to it turn into a very expensive paperweight. Luckily, there are four tools within Mac OS X that can help you find and correct your problem.

First is Apple System Profiler. The Apple System Profiler is used to find out exactly what is installed on your Mac and where. If you click on the Apple logo in your upper left hand corner, and then click About This Mac, you will get a handy little pop-up window with some basic system info. Click the More Info button, and you get Apple System Profiler. It is very useful for learning about your Mac’s processor, memory, and any attached peripherals. It is also very helpful for identifying peripherals connected via USB, SCSI, etc. Use the Applications tab to list all applications, and mounted volumes.

If Apple System Profiler did not tell you what you needed to know, head over to Disk Utility. In Mac OS X, the older operating system’s applications Disk First Aid and Drive Setup are combined to make Disk Utility. With Disk Utility, you can:

• Get information about any disk attached to your computer
  
  
• Fix disks so that they mount and function properly
  
  
• Partition disks
  
  
• Erase and reformat disks
  
  
• Set up a RAID array
