Taking screenshots is a very useful feature for sharing with others or getting troubleshooting help. Mac OS X gives you a variety of tools for creating screenshots. These tools give you lots of control over how your screenshots are made.
Taking a Full-Screen Screenshot
⌘ Command+⇧ Shift+3 If your speakers are on, you’ll hear a shutter sound. This command will capture the entire image that your monitor displays.
Find the screenshot file.
The screenshot will be saved as a PNG file on your desktop, labeled with the date and time that you took it.
⌘ Command+Control+⇧ Shift+3 This will copy the image instead of creating a file, allowing you to paste it into another program.
- To paste your screenshot, open the program and press .
Taking a Partial Screenshot
⌘ Command+⇧ Shift+4 This will turn your cursor into a crosshair.
Click and drag to create a box.
This box will determine what is captured for the screenshot.
Find your screenshot.
After creating the box, the screenshot will be taken and the file will appear on your desktop. It will be in PNG format and labeled with the date and time it was taken.
- If you’d rather copy the screenshot to your clipboard instead of creating the file, press .
Take a screenshot of a specific window.
If you want to capture an entire window, but not your whole screen, press ⌘ Command+⇧ Shift+4 and press Space. The crosshair will turn into a camera. Click thew window that you want to capture.
- Like the other methods, this will create a file on your desktop.
Open the Preview utility.
If you don’t like using keyboard shortcuts, or want to save your screenshots in a format other than PNG, you can use the Preview tool.
- You can find the Preview tool in the Utilities folder in your Applications folder.
Click the “File” menu and select “Take Screenshot”.
If you select “From Selection”, your cursor will change into a crosshair and you can create a rectangle to make the screenshot. If you select “From Window”, the cursor will change into a camera and you can click the window you want to capture. If you select “From Entire Screen”, Preview will capture your entire screen.
Review the screenshot.
Once you’ve captured your screenshot, it will appear in the Preview window. You can review it to ensure that the right parts have been captured and that it isn’t showing anything you want to hide.
Save the screenshot.
Click the “File” menu and select “Export As”. You can use the pop-out menu and select the format that you want to save it as, including JPG, PDF, and TIFF.
Using the Terminal
Open the Terminal.
You can find the Terminal in your Utilities folder, which is in the Applications folder.
- Using the Terminal gives you some extra features, such as a timer or disabling the shutter sound. Use can also use SSH to capture remote screenshots of difficult screens, such as the login window.
Take a basic screenshot.
Type screencapture fileName.jpg and press ⏎ Return. This will save the screenshot to your home directory. You can add a path to the front of the file name to specify a different location for the screenshot file.
- You can change formats by typing screencapture -t png fileName.png. You can also use pdf, gif, or tiff.
Copy your screenshot to the clipboard instead.
If you’d rather copy the image instead of creating a file, type screencapture -c and press ⏎ Return.
Add a timer to the screenshot command.
Using the basic screenshot command, the screenshot will be taken immediately, which means your Terminal window will appear. You can use a timer to give yourself time to hide the window and open anything that you want displayed.
- Type screencapture -T 10 fileName.jpg and press . This will give you 10 seconds until the screenshot is taken. You can change 10 to whatever delay you’d like.
- Not all programs allow you to capture the screen. This is especially common in video players and games to prevent unauthorized reproductions.
