Capturing images from the screen (screenshot) is a very useful function to share them or get help with troubleshooting. Mac OS X has several tools for creating them. These tools provide various possibilities for controlling image capture.
Steps
Method 1 of 4: Full Screen
Step 1. Press the Command + Shift + 3 keys simultaneously.
If the speakers are turned on, you will hear a sound similar to that of a camera shutter. This command will capture the entire image displayed on the screen.
Step 2. Find the screenshot file
The image will be saved as a-p.webp
Step 3. Press Command + Control + Shift + 3 keys simultaneously to copy the image to the clipboard
This way the screenshot will be stored in the clipboard, rather than in a file, and can be pasted into another program.
To paste the screenshot, launch the program and press Command + V
Method 2 of 4: Partial Screen
Step 1. Press the Command + Shift + 4 keys simultaneously.
The command will turn the cursor into a crosshair.
Step 2. Click and drag to create a frame
The box circumscribes the part of the screen you intend to capture.
Step 3. Find the screenshot
After creating the tile, the screenshot will be captured and the file will appear on the desktop. This will also be in-p.webp
If you prefer to copy to the clipboard instead of creating a file, press Command + Control + Shift + 4
Step 4. Take a screenshot of a specific window
If you want to capture an entire window, but not the whole screen, press Command + Shift + 4 and then press Space. The viewfinder will turn into a camera. Now click on the window you want to capture.
As in the other cases, a file will be created on the desktop
Method 3 of 4: Using the Preview
Step 1. Launch the Preview utility
If you don't like using keyboard commands or want to save screenshots in a format other than PNG, you can use Preview.
Find this tool in the Utilities subfolder of the Applications folder
Step 2. Click on the "File" menu and select "Take a Screenshot"
If you choose the "From a selection" option, the cursor will turn into a crosshair with which you can create a rectangle to enclose the image. If you choose "From a window", the cursor will turn into a camera and you can click on the window you want to capture. If you choose "From Full Screen", the Preview will capture an image of the entire screen.
Step 3. Review the screenshot
Once captured, the screenshot will appear in the Preview window. You can make sure that it has been captured correctly and that it shows the desired parts while masking the others.
Step 4. Save the screenshot
Click on the "File" menu and select "Export As". You can use the guided assistance menu and choose the format you want to save in - for example JPG, PDF or TIFF.
Method 4 of 4: Using the Terminal
Step 1. Launch the Terminal
You can find the application in the Utilities folder located in the Applications folder.
Using the Terminal program makes some additional functions available, such as a timer or the ability to mute the shutter sound. You can also use the SSH (Secure SHell) network protocol to remotely take screenshots of complex screens - the login window, for example
Step 2. Take a basic screenshot
Type "screencapture filename.jpg" and press Enter. This will save the screenshot in the home directory. You can add a path before the filename to save it in a different location.
You can use the Terminal to change the format by typing "screencapture -t-p.webp" />
Step 3. Alternatively, you can copy the screenshot to the clipboard
If you prefer to copy the image instead of creating a file, you can do so by typing "screencapture -c" and pressing Enter.
Step 4. You can add a timer to the screenshot command
Using the basic command the screen will be captured immediately and this means that you will also capture the window in which the Terminal program was started. A timer gives you time to hide the program window and open whatever you want to see.
