Stamp your desktop with essential system information!  
System Stamp will apply information such as host name, operating system version, memory, and processor configuration onto your desktop wallpaper.  Freely choose the information items that you want to show, and the order of the items.  The font and color can be adjusted, as well as the placement of the text.  You can also choose to use a solid background color, instead of an image.  Multiple monitors are supported, with separate backgrounds and stamp items for each monitor.
System Stamp does not change your original desktop wallpaper image, but generates a new image based on the source image you choose.   
System Stamp is a great utility for users or developers who want to know critical information about the system they are using — with just a quick glance at the desktop!

Release notes:
Support for Apple M1 hardware, macOS Big Sur, and dark mode.
