How to take a screenshot on Mac



  • The following commands are used to take screenshots in the system:
    - Command + Shift + 3 - a snapshot of the entire desktop
    - Command + Shift + 4 - a snapshot of the allocated table space
    - Command + Shift + 4 and + Space (window selection) and + LMB directly snapshot.



    Where: Command = WinKey, Space = Space, LMB = left mouse button.
    On a hackintosh, depending on the definition of the keyboard type and the selected layout in the menu, the Command role may be performed by Option = Alt
    You can change this state of affairs by referring to "System Settings / Keyboard / Modification Keys.



  • Additional functions:
    - Hold Option to start selection from the center
    - Hold Shift to set the selection only horizontally or vertically
    - Hold space to move set selection
    - Hold shift + space to fix horizontal or vertical selection
    - Press Esc or Command + Enter to cancel
    - Press the spacebar to select the desired window

    By default, the system has a PNG image format with a shadow. In fact, this is not the only supported format and the default value can be changed. There are several ways to do this. The first involves the use of third-party utilities with the corresponding functions (commands). The second system through the commands in the terminal. In both cases, for the changes to take effect, a re-log must be performed.



  • In order to change the format in which the screenshot is saved, run in the terminal:
    The code:
    defaults write com.apple.screencapture type png
    killall SystemUIServer


    Where: png can be replaced by -

    jpg, pdf, tiff, etc.
    From myself I note that when using the JPG format, the system very optimally balances the quality and weight of the file.
    Each line is executed through Enter.
    You can return it back with the same command but with a different screenshot format - png

    By default, screenshots are saved to the desktop.


  • To replace the place where the screenshot is saved, write in the terminal:
    The code:
    defaults write com.apple.screencapture location / Users / Roger / Documents / Screenshots
    killall SystemUIServer


    Where: as an example, the path / Users / Roger / Documents / Screenshots can be any desired.
    Each line is executed through Enter.
    You can return it back with the same command but with a different specified address ~ / Desktop.



  • In order to disable the addition of a transparent frame, which if you use, for example, the JPG format, becomes just white, you must enter the command in the terminal:
    The code:
    defaults write com.apple.screencapture disable-shadow -bool true
    To return back to enter the command:
    The code:
    defaults write com.apple.screencapture disable-shadow -bool false


    How to make quick annotations in a screenshot or PDF



    There is a feature in Snow Leopard

    Annotation, which is available in the system application

    View. You just need to click on the screenshot file, etc., so that it opens in the view, where you can make all sorts of notes, selections, arrows, write something on the image, select a font and color ...

    The "Annotation" toolbar will become available after clicking the corresponding button in the viewing panel (configured through the context menu)
    Then you can optionally choose in what format to save the file by accessing the menu of the "View" program - File / Save As /
    Where you can choose the format and the desired quality. Everything is fast, high-quality and no Photo Shop :)
