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:

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.
