Well fuuuuuuuu. I guess that's it folks. https://news.ycombinator.com/item?id=19966135
You can take this a few different ways. First, Marzipan is a bad effort because parts of AppKit literally CANNOT be replicated/re-implemented. Thus AppKit lives forever.
Alternatively, that perhaps AppKit really is dead and that Marzipan and Electron are the only way forward.
Either way, this is a huge blow to the Mac as a platform. They aren't updating and improving it because they literally can't.
Perhaps Marzipan isn’t just a cheap way to get apps on to MacOS. Perhaps it’s literally the only way forward for Apple, by threat of death.
Marzipan - I didn't see it before but maybe it really is the end of the line for AppKit. There's a lot more riding on this than I thought. Who knows what the institutional knowledge of it is any more?
