cp: nbopen/icons/ipynb_icon_1024x1024.png: No such file or directory

I have this problem when trying to integrate while file management system on Mac (running macOS Mojave). Solution?

Sounds like it's looking for an extra icon size that's not there. I don't use Mac myself, so there's not much I can do about issues with it.

As commented in osx-make-iconset.sh, there is no 1024x1024 icon that could be used to generate a retina version of the 512x512 icon. This should only give a warning, however, and not affect any functionality (at least I never had a problem as far as I remember).
@qsimeon Is there anything that does not work because of this warning?

Simply create a copy and rename the ipynb_icon_512x512.png to ipynb_icon_1024x1024.png.
