New Super Mario Bros 2 Shows Flickering Instead of showing the Main Menu

Issue : When I open up New Super Mario Bros 2 on my Mac , the screen flickers instead showing the main menu. I can hear the music. After a while the emulator crashes. Computer Specs :
Model Mac mini (Late 2014)
Processor 2.8 GHz Intel Core i5
Operating System MacOS High Sierra Version 10.13.5
Memory 8 GB 1600 MHz DDR3
Graphics Card Intel Iris 1536 MB
Citra Version Nightly #760
Here is a Photo and a Log File.

/user/ublg.lst not found
NGWord Bad word list seems to be missing.

also you can try to disable ‘Enable Hardware Shader’

It works but the game lags

Mac OS OpenGL drivers are very poor and do not support features that Citra uses for speeding things up. If you want to get way better performance, try installing Windows or Linux through BootCamp.

Ok thanks for the help
