If you have upgraded your Apple Mac OS to 14.x.x, then you may find it strange that the screenshots are not copied into the clipboard. The screenshots taken are saved to Desktop by default. And also it appears on the bottom right corner for a few seconds so that you can click on that copy image.  But that is annoying!
