Its processor speed only says 1.87???THANKS

One way to do this is by looking for the Macintosh HD icon on your desktop like this:

Right click (or CTRL-click if you’re using a single button mouse or a laptop) on the icon and you should see this:

Left click on ‘Get Info.’

The screen that appears next should have a bunch of information about your hard drive, and in the ‘General’ section (you may have to click the triangle to open up the information) you should see this:

The capacity on this computer states 111.47GB which is actually a 120GB hard drive (visit this wikipedia entry for an explanation of why the difference in sizes under the section titled ‘Consumer Confusion). It’s got 27.81GB available and 83.66GB used.
