Learn how to change the default naming scheme for screenshots on your Mac, so macOS saves all future screen grabs with custom file names.
Screenshots you take on a Mac are saved with the default “Screenshot Date Time” file name, where “Date” and “Time” are replaced with the actual timestamp.
You can change the default file naming scheme for macOS screenshots to use a custom string like your first and last name, company name, or anything else you like.
Change the screenshot file naming scheme on Mac
1) Open the Terminal app on your Mac from the Applications > Utilities folder.
2) Paste this command in Terminal, replacing “iDB” with whatever you want, then press the return / enter key.
defaults write com.apple.screencapture name "iDB"
3) Now paste the following command and press return / enter.
killall SystemUIServer
All new screenshots you take on this Mac will be saved using the custom file name you just set, with the screenshot timestamp appended to the file name.
Reverting the change
To go back to the default screenshot name, use this command in Terminal:
defaults write com.apple.screencapture name "Screenshot"
Extra info: In older OS versions, Apple used Screen Shot instead of Screenshot.
Mastering screenshots on the Mac
You can also instruct macOS to remove the capture date and time from screenshot file names.
You can always find all screenshots on your Mac, regardless of their naming scheme or save location.
And if you don’t like the shadow effect on screenshots, you can remove it easily by pressing a modifier key when capturing a screenshot or remove it permanently.
