Can I play Starfield on either iOS or MacOS?

I have a feeling this is a very naive question, but I cannot find a reliable answer. It seems with the Xbox Game Pass app it is possible to play Starfield on either iOS or MacOS. Do I understand that correctly? I’ve read a couple of articles that imply this works but haven’t found a definitive answer.

Assuming so, does anybody have experience running in this environment?

With gamepass ultimate you can play / stream it in your browser.
There’s no native way to play it. Might work under parallels.

Yes, it is available here: Play Starfield | Xbox Cloud Gaming (Beta) on  Xbox.com

This is streamed from Microsoft, so there is some input lag and as the previous posted mentioned a subscription. YMMV depending on the quality of your Internet connection.
