Checking the MacOS Version and the Installed RAM

Both of these items can be viewed from a common window.

1) Go to the Finder. You can do this either explicitly or implicitly:

• Explicitly: On the top, far-right of menu bar, click on the Application Menu icon. Then choose "Finder" from the list of running applications.
  
• Implicitly: Click on the desktop (the background). If they don't know what that is, tell them to click on the Trash Can (the Trash Can is part of the Finder).

2) Click on the Apple Menu (far-left of menu bar) and choose "About This Computer" or "About This Mac"(the very first item in the menu). Some older Macs may say "About This Macintosh".

3) The screen has two portions: NOTE: If this screen says "Mac OS X" or "10.X" then it will look very different. That's all you need to know for now, and don't worry about the RAM.

• Top Part: This will show the "System Software" version. It will also show the "built-in" memory, and the "total memory" (including virtual memory).
• Bottom Part: This part shows all running applications with a bar graph showing how much memory is allocated to each, and how much of the allocated memory is currently in use for each.
