Doesn’t work on Yosemite, but maybe it does?

In less than ten minutes it installed, I tried to open it using the button above, and it gave me an error message stating it had unexpectedly quit. Such a short life span.
But I just clicked on the icon in Launchpad so I could right click and maybe delete it, and it opened right up. So will try it out.
