Although you can use a build in OS X utility called “Grab” to take screenshots, but I’ve found that it doesn’t take the screenshots with the drop down shadow. So here are some simple shortcuts for taking screenshots in Mac OS X.

• Command-Shift-3: Take a screenshot of the screen, and save it as a file on the desktop
• Command-Shift-4, then select an area: Take a screenshot of an area and save it as a file on the desktop
• Command-Shift-4, then space, then click a window: Take a screenshot of a window and save it as a file on the desktop
• Command-Control-Shift-3: Take a screenshot of the screen, and save it to the clipboard
• Command-Control-Shift-4, then select an area: Take a screenshot of an area and save it to the clipboard
• Command-Control-Shift-4, then space, then click a window: Take a screenshot of a window and save it to the clipboard

You can choose which format to save the screenshots by issuing the following commands in Terminal

defaults write com.apple.screencapture type {image_format}
killall SystemUIServer

Replace the {image_format} with one of the following :

• jpg
• tiff
• pdf
• png
• bmp
• pict
