Question about HTC Vive Cosmos

By manufacturer : Operating system: Windows® 10
There is some test for Steam VR for MAC but the market is too small so it will take some time!
So you could use the Cosmos via Steam VR MAC!

Otherwise look at Oculus, they seem to be compatible with MAC! You can also use it directly via smartphone.
Oculus Quest you are good to go!
Oculus Quest 128GB
I don't know about Oculus yet, but this one will also be worth buying!
