How to change where screenshots are saved on Mac
Step 1: Make sure to create the folder you want the screenshot to go to.
Step 2: Search for Terminal in Spotlight Search in the top-right menu bar.
Step 3: Open Terminal and type the following command: defaults write com.apple.screencapture location ~/Documents/Screenshots
Step 4: To apply the changes, enter the following command: killall SystemUIServer
If you entered the commands successfully, your screenshots will now save to a Screenshots folder within your Documents.
Note that you can type any directory that you wish to save screenshots to, as it doesn’t have to be ~/Documents/Screenshots if you would prefer something else. For example it could be Documents, or Downloads.
To revert back to saving screenshots to your desktop, enter the following command:
defaults write com.apple.screencapture location ~/Desktop
followed by:
killall SystemUIServer
