How to take screenshots on Mac



  • To take screenshots in the system, use the following commands:
    - Command + Shift + 3 - a snapshot of the entire desktop
    - Command + Shift + 4 - 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 the hackintosh, depending on the definition of the keyboard type and the selected layout in the menu, the role of the Command can be performed Option = Alt
    Changing this state of affairs is possible 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
    - Keep a space to move the 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 snapshot image format. In fact, this is not the only supported format and the default value can be changed. In this case, there are several ways. The first involves the use of third-party utilities with the appropriate functions (commands). The second system through the commands in the terminal. In both cases, for the changes to take effect, you must perform a re-log.



  • In order to change the format in which the screenshot is saved, run in the terminal:
    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 format of the screenshot - png

    By default, the screenshots are saved on the desktop.


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


    Where: As an example, the paths / 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 another specified ~ / Desktop address.



  • To disable the addition of a transparent frame, which in the case of using for example the JPG format will turn white, you need to enter the following command in the terminal:
    Code:
    defaults write com.apple.screencapture disable-shadow-bool true
    To get back to enter the command:
    Code:
    defaults write com.apple.screencapture disable-shadow-bool false
