I've just realized that my version of Isadora 2 is attempting to open the file instead of Isadora 3

 You can right-click these menu icons, and select 'open file location'. In the folder that opens will be these 2 Isadora shortcuts.. If you check properties on them you can determine which is for Isadora 3 and for Isadora 2.. then rename them accordingly. These Icons will then show-up in your menu with the name you gave them..
I do this with every beta version I install, so that I can have dozens of Isadora versions installed. 

VLC should do it.

The software has been updated in 2016 and relied on QuickTime support from Apple to grab the necassary information / texture's. Since Apple has ditched support for QuickTime it means that the software wont work on newer versions of macOS. Like the Github issue explains you have to rebuilt the software against a newer version of OpenFrameWorks.

Thank you @Juriaan  and @bonemap  for your solutions !! I will try it

@dillthekraut I get it. Thanks for the educating

Added a bit to my original post about using the Data Array actor with textfiles, containing my controller and note values, to map my midi controller to parameters. It is a super useful actor that made quick work of mapping the controllers, and allowed for flexibility in making changes.
