Catalina update caused a tenacious pop up.
The second I updated to Catalina I got the following dialogue. "[app] is an app downloaded from the Internet. Are you sure you want to open it?". The app in question was an installer that I no longer need and so I hit cancel. However this was not the end. The dialogue box will not go away, no matter what. The only thing I haven't done is hit open, because I do not want to open it. It told me when and what I downloaded so I went into my downloads and removed the file. I also tried restarting the computer. The dialogue box remains. How do I get rid of this pop up?
