My wife was working on her MacBook Pro (Big Sur 11.6) tonight. She normally has lots of icons on the desktop for projects she is working on. (Yes, I know she shouldn't) but tonight after the lid was closed and she tried to awake it from sleep, all the icons disappeared and the desktop was completely empty. She may have accidentally hit some magical combination of keys in trying to wake up the MB but I haven't been able to learn that such a key combination exists. Searches on the internet suggest you need to use Terminal commands or some extra app to achieve such a result. In any case when she brought the computer to me for help, I asked her the name of one of the files she had on the desktop. Thinking she somehow got everything to go into some folder somewhere I typed that filename into the search box to try and locate where it might be hiding. As soon as I clicked on it to select it (intending to Get Info on it) all the missing icons instantly filled the desktop again. I have no clue what might have happened. Any ideas?
