I can't believe that nobody on this forum has even a comment on this problem. You guys have always been so knowledgeable and helpful in the past. One of the most annoying aspects of this OSX message is that I can't open any apps at boot-up - they all fail at the error message.
I have a new iMac which, when I open applications for the first time in a session, gives an Apple error message, "You are opening the application, ****, for the first time .....". It doesn't always do it but there are some apps for which it does it every time. I have to click OK to open the file.
How do I get rid of the message?
