I would like to display a message, for example, the OS Version, the installed tool versions etc on the Desktop background of macOS.

I understand that the lockscreen text can be edited, I am not talking about that. That is not what I am interested in.

I know there is a way because I have seen my colleagues at my previous job do this.

NOTE: I want to do this from command line.

It is possible using NerdTool or GeekTool. You can create custom ones writing command line codes or display content from logs.enter image description here

Find inspiration for code from here and mac AppStorm made a great article with lots of crazy geeklets .

    @JordanKasper Geektool still works. Link - www.tynsoe.org/v2/geektool/

  • I instead resorted to using imagemagick to annotate the a jpeg and used it as a wallpaper. I love this way because I can periodically update the wallpaper with whatever message I want from my script
