Add new work spaces for iMac 10.8 / mountain lion

A lot of people complain that the Exposé / Spaces properties were disabled in the new Mac OS X Mountain Lion.  Some even have downgraded the system to a previous version. Actually to add a new space is easier in the new system, if you know how to:-).

1. Press key on the keyboard. The current desktop will shrink. On top of it, two shortcut images will show.  The dashboard is on the left.  The current desktop is on the right. 
2. Now move the mouse cursor to the top right corner of the screen.  A new shortcut image with a '+' sign appears.
3. Click this image to add as many places as you required.

Another good thing about the new system is that it now has removed the memory usage limits. The Xcode can automatically adopt the C++11 standard.  This has made it quite computational friendly.  I am going to spent more time on my iMac machine later.
