Question: Pop-up window: Apple wants to make changes
I repeatedly get a pop-up window saying “Apple want to make changes. Enter your password to allow this.” There is no mention of what is to be changed nor why. I, of course, don’t enter the password and have to close three iterations of the window before it goes away until the next day.
Is this an attempted hack of my computer? IF so, how to delete it from my system?
