Allow a few moments for it to be stored on your computer's desktop.
To copy a screenshot to your clipboard, hold down the control key while taking it.
Selective section:
shift + command + 4
Then, with your mouse or trackpad, use the crosshair to pick the area you want to capture.
You may drag the chosen part by pressing and holding the space bar.
To cancel the screenshot, use the escape key.
To take the screenshot you want, let go of the mouse button or trackpad.
If you want to copy it to your clipboard, hold down the control key.

Take a screenshot of a window, a menu, or the Dock:
shift + command + 4 + space bar
You'll see a camera icon in these screenshots.
When you hover your mouse over different windows, the menu bar, menu items, or the Dock, a blue glow indicates what you're about to capture.
To take a screenshot, click the window or menu.
You may also remove the shadow border from window screenshots by holding down the option key.
How to Take a Screenshot on Mac

To take a screenshot of the Touch Bar on a MacBook Pro:
Shift + command + 6
To copy the screenshot to your clipboard, add the control key to the shortcut.
To use the macOS Screenshot app:
Go to the App Store and search for "macOS Screenshot."
Use 5 + shift + command
You'll now see choices for recording the entire screen, a selected window, or a specified piece of the screen, as well as the ability to start a screen recording (full or partial), "Options," and "Capture."
To change your screenshot preferences, go to Options.

A timer, save to settings, the ability to disable the floating thumbnail after taking a screenshot, display/don't show mouse pointer and remember last selection are among the features available.
You may also utilize the Capture button in the menu (or press the return key)

A handy way for quickly capturing plenty of screenshots:
Setting a chosen part with the menu, choosing "Remember Last Selection," then using the shift + command + 5 shortcut followed by the return key, which will take the screenshot, is one.
Another trick for MacBook Pro users is to use shift + command + 4 or 5 to obtain screenshot controls on the Touch Bar.
Another thing to bear in mind is that screenshots are not permitted in the Apple TV app. Go to System Preferences > Keyboard > Shortcuts > Screenshots to configure the keyboard shortcuts for screenshots.
Change the default screenshot format to JPG:
Screenshots on Mac are saved to the desktop as PNG files by default, which are bigger files. Follow these procedures to change the default to JPG (lower file sizes):

Launch the Terminal application.
"defaults write com.apple.screencapture type JPG" is the command to use.
Press return (enter)
