Does everything still work in mac/linux?

[freddyaboulton]

Yes tested on mac!

[freddyaboulton]

I guess the true test would be to do ship an release candidate of @gradio/preview but everything is working in the dev environment

Tested locally (macOs and Asahi linux) and looks good!

Thanks @freddyaboulton!
