According to the original web page, it requires at least 10.12 operating system for several versions. I have version 0.18-16146 installed and although the program opens, the window does not show any controls. So it doesn't seem to be compatible either. And since my time is money, I'm not going to spend another minute with him. Nor have I used it in the years that I have it installed, I have other much better options and they don't cause me so many problems to install a working version. At a minimum, they could indicate on their website the latest versions compatible with each operating system. But as always, the Apple norm indicates that the user must be torpedoed and forced, yes or yes, to always update to the latest versions.
