Hi and thanks for letting me join.

I've just installed Kodi 21 omega on my 2013 Imac running Catalina and it is opening, but not in a  new window like it did when I had it before..
Any ideas?
Thanks

You'll need to be more clear. Do you mean it is opening fullscreen? If so hitting backslash \ should put it into windowed mode.

For more precise configuration then see https://kodi.wiki/view/Settings/System/Display

If you mean something else then provide more information and we may be able to shed some light on the situation.
