How do I retrieve screenshots on a MacBook Pro?

Re: "Retrieving screenshots on MacPro

How and where do I retrieve screenshots on my MacPro laptop?"

Depends on whether or not your Mac is using the default settings.

If so : See if they are waiting for you on the Mac desktop.

If not: Please read on:

Apple Support's linked article below may be helpful:

Take a screenshot on Mac - Apple Support

Eg: says:

"Find your screenshots

• By default, screenshots save to your desktop with the name ”Screen Shot [date] at [time].” You can change the default save location in the Options menu of the Screenshot app.
• Instead of waiting for the screenshot to be saved to your desktop, you can drag the thumbnail that appears in the corner of your screen, then drop it in another location. 
• To save a screenshot to the Clipboard instead of your desktop, Control-click the screenshot thumbnail that appears in the corner of your screen, then choose Save to Clipboard from the shortcut menu that appears. Or press Control in addition to the other keys you press to take the screenshot. For example, instead of pressing Shift-Command-3, press Control-Shift-Command-3."
