Hello,
I hope you can help me here.
I have exported my app using NW.js for MacOSX.
When I look at the icon on the Mac, it looks like this. (See screenshot) Other icon sizes look fine.
In the project I have stored all sizes. 16x16,32x32,64x64,128x128,256x256,512x512.
I also looked again in the Apple Documentation and found nothing.
Thanks
