Problem with Recent Security Update 2020-04 for High Sierra

Try to do my update and it doesn't want to restart, instead keep having this popup saying: "Available updates have changed - Click show details to see the available updates" start again the same process in a round robin!


i have a 2011 iMac running High Sierra 10.13.6
