My wife's Macbook Pro school (she is Kinder teacher). Today out of nowhere question mark icons appeared in the dock for man popular apps like Safari and System Prefs. I added them back in by launching them and then dragging from R to L side of dock. But I cannot delete the invalid ? icons remaining in the dock. Tried moving to trash and moving to desktop. R click shows an options window but no options are available. Any ideas?
 
what os version and model? one version you have to ctrl+click to open options and remove, another you have to click+hold, drag to trash and hold it there for a couple seconds then release.
 
Nevermind, the school tech department pushed out a software update of some sort that caused the problem. They fixed it 2 days later. Appreciate the help effort.
