I'm using iMac and followed the process as demonstrated in the Youtube video. When I right click to execute the matRad app, it never opens. After a minute it shows the matRad label on top left but GUI never pops up; and top left labels don't give options either. I'll have to force quit to close the app. Any way around this?

Additionally, I tried source code from within Matlab but when I attempted optimization within GUI, it gave me an error regarding some IPOPT thing missing. Attached is the image of the error.

Thanks
