easiest way to find your serial number

Click  > About This Mac… then click on the greyed out text underneath the black ‘Mac OS X‘.

It probably says ‘Version 10.7.2’. When you click on it, it will change to the OS build number. Click on it again and you’ll see your serial number. Easy 🙂




how to take a screenshot



We all like to take happy snaps at Christmas 🙂 , but there’s no need to buy expensive software to snap the wonders you or your family produce on your Mac computer screen. Mac OS X has a number of built-in ways to take screenshots. The simplest is to use the universal hotkey combination:

Command-Shift-3

This will immediately take a snapshot of your entire screen and dump it on your desktop as .png file. Try it now and have a look!

If you want to select only a specific region, try this

Command-Shift-4

Move your cursor, and you’ll see it’s turned into a cross-hairs by which you can select any part of the screen you want. You can also press the spacebar after you invoke this command, and the cursor will turn into a camera icon. This lets you accurately select individual windows for the shot, instead of drawing round them.

If you are taking the screenshot to immediately paste it into a post, email or document and you don’t particularly want to keep a saved copy of it, then add the control key to either of the previous commands (e.g., command-control-shift-3). This will dump the screenshot into the clipboard rather than save it as a file. All you do next is go to the window you want to paste it in, and hit Command-V.

Finally, if all these hotkeys are too much to remember for the occasional screenshot, remember you can always access screenshots through the Preview.app menu (see main image above).

Happy snapping folks! 🙂

Here’s the summary of the main commands:
