Apple has just announced Project Catalyst on WWDC 2019, which allows iOS/iPads to run on macOS without modification. This is AWESOME.

Of course it's still beta, but it's already available today for developers to test.

We'd love if React Native could build and work perfectly on macOS.
If possible, that should be a supported scenario.

@hramos @cpojer Can we leave this open? People are coming looking for this info and we can centralize here.

Someone got this working last year pretty quickly. It should be easier to support Catalyst than tvOS, for example.

I agree it'd be useful to have a note in one place somewhere about Mac support to set expectations and mitigate speculation.

Ya I'm looking for docs and experience on this. How automatic is such "porting" from iPad to Mac?
