Let's say you frequently drag icons around on your desktop and often find that they are all jumbled together, icons overlapping one another. To better organize the icons on your desktop, follow one of the two options below:
1. Click on the View menu in Finder and select Clean up to make all icons align properly.
2. If you want your desktop icons to be auto-arranged, you can do so by clicking on the View menu and then hold on the ALT key on the keyboard until you see the "Keep Arranged By" option show up on the View menu. Click on the "Keep Arranged By" option and then select the criteria you want to arrange your icons by, such as by Name, Date created, Size, Kind or Label.
