A screenshot on a Mac can be made using standard system tools. You do not need to install any additional applications. Now I will tell you how to take photo and video screenshots using macOS Mojave as an example.
Basic keyboard shortcuts
CmdShift3 – take a screenshot of the entire screen and save it to the Desktop;
CmdShift4 – select an area of the screen, take a snapshot and save it to the Desktop;
CmdShift4 then space – makes it possible to select a specific window, take a snapshot and save it to the Desktop;
CmdShiftfive – will bring up a small menu, where you can clearly see all the features of the built-in screenshots. You can also record a video demonstration of the screen from here;

All these combinations can also be used with the key Ctrl… In this case, instead of saving to the Desktop, the picture will be immediately saved to the clipboard.
MacOS provides a number of modifier keys that you can use when selecting a capture area. To use a modifier, you must hold down and hold the corresponding key.
- space – fixes the size of the selected area, and when moving;
the pointer moves the entire selected area instead of resizing;
- Shift – allows you to change only one of the sizes of the selected area;
- Option – the area will resize symmetrically to the selected center.
How to choose a screenshot format
By default, macOS stores screenshots in PNG format. But you can change this format to any other.
To save screenshots in JPG, run the following commands in the Terminal:
defaults write com.apple.screencapture type jpg
In addition to JPG and PNG, macOS also supports tiff, pdf, bmp, and pict.
How to remove shadow from a screenshot
By default, all screenshots are taken with a slight shadow around the entire outline. You can remove the shadow with the following commands:
defaults write com.apple.screencapture disable-shadow -bool true
Return the shadow back:
defaults delete com.apple.screencapture disable-shadow
Location of Mac screenshots
By default, screenshots are saved to the Desktop, which quickly creates clutter and is in no way suitable for those who follow the principles of a minimalist Mac.
It is best to create a separate folder for them:
defaults write com.apple.screencapture location ~/Pictures
Where ~ / Pictures is the path to the new folder.
Return screenshots back to Desktop:
defaults write com.apple.screencapture location ~/Desktop
How to optimize screenshots
If you are going to publish screenshots somewhere in a blog or forum, it is better to optimize their size before publishing. This will make them load faster.
For PNG optimization use ImageOptim. And for JPG – JPEGmini.
