Hello,I play this game for a year on PSN  .Recently psn game keys almost expire .I got a XBOX  from my bro as gift .I want to build games for consoles,but i meet some problems now.
1) Can I use XBOX One or XBOX One S for development / testing?
2)I'm on a high-end Mac Pro, do I  need a Windows PC to develop games for xbox when I use Unity? 
3) I think Unity Cloud can not be built for XBOX  or maybe for Universal Windows.Do I need Windows to build the game?  

Who can share some experience ?thank you
