I did that. I also tried uninstalling Java then reinstalling, but that made no difference. It appears to install the latest 1.8-211-12 version.

I move MinimWatch into the Applications folder and double click on it It comes up with the "application downloaded from the internet" warning. I hit continue and nothing happens. MinimWatch doesn't appear on the menu bar and doesn't show up on the Force Quit list.

What am I missing?
