MacOS Screenshots can be automatically generated with a filename that is too long and complex, that looks like:
'screenshot 2024-02-22 at 9:00:00AM.PNG'
The screenshots can be manually renamed, or there is a command to globally update how those screenshots are stored.
How to Remove the Date and Time
To remove the date and time that is appended to each screenshot you take, use the following command in Terminal and then hit Enter
defaults write com.apple.screencapture "include-date" 0; killall SystemUIServer
To open the Terminal:
Click the magnifying glass icon in the menu bar or press Command-Space to open Spotlight Search. Then, type "Terminal" and double-click the search result.
