How do I take a picture (screenshot or snapshot) of my computer screen and send it to someone?

Perhaps you want to share the way your screen looks with someone who needs your help or you need to include a view of the screen you’re seeing so that it can be enhanced or modified during development of a custom application.

Here are some simple instructions:

On a Mac OS…

  1. Press Command-Shift-4 on your keyboard.
  2. Press the space bar. Your cursor will change to a camera pointer. Move the pointer over the window you want to take a picture of.
  3. Click your mouse. The system will take a screenshot of the window and save it to your desktop as a file called Screen Shot DATE TIME.png.

Sharing the Screenshot

Once the snapshot is saved to your desktop, you are now able to share it. Simply drag and drop the screenshot from your desktop into a message you are typing in Mail, Outlook, or Basecamp. There is no need to place the screen shot into a Microsoft Word document first.
