I found a simple way to play orape and possibly krelay on macOS

Basically look up the software called wine.

Pretty much makes orape run in a windowsOS environment.

If you're interested on more, just reply.

Moved to discussions. You shouldn't need WINE to run Orape. For Orape (the swf version), all you need is a projector that's built for your OS: http://www.adobe.com/support/flashpl...downloads.html
Get "download flash projector" for mac os.

I've seen plenty of tutorials for this, you didn't find anything.

it could still be useful if you want krelay though. afaik, it only works in a windows environment
