Mac screenshots: Command + Shift + 3 and Command + Shift + 4
Filed in: System Preferences Add comments
Maybe this is something veteran Macheads know, but this Mac-wannabe just learned how to take screenshots by using:
Desktop screenshot
Apple/COMMAND + SHIFT + 3
Crosshairs select screenshot
Apple/COMMAND + SHIFT + 4
The default format is .TIFF which can be changed to something else by a little terminal magic:
Copy the “defaults write” line below, paste it into the Terminal window, and press Return.defaults write com.apple.screencapture type jpg
The article shows changing from TIFF to pdf, but you can use other formats as well like png. To have the setting take effect you’ll either need to logout and login anew or enter the following terminal command:
killall SystemUIServer

The screenshot above shows the whole terminal process. Takes like less than 30 seconds.
