Can't install Xbox Game Pass Ultimate (Xbox App) on Windows 10

So on your PC you need to make sure the
game pass ultimate account is signed into the
Microsoft store app, You might want to try installing the
xbox(beta) app on windows as well and try downloading from there.

Not all of the game pass games between Xbox and PC are the same, the xbox(beta) app will show you all the available and installed windows game pass games

CAN xbox(beta)

I'm assuming you mean the Xbox beta App, so you can play games on Xbox game pass for PC or Ultimate. You need the latest Windows 10 version to be able to install the app, there is no other way. Also that app is only so you can find and install the games
from game pass easier. You can still find and download the games from the Microsoft store app, but they may not work without the latest version of Windows installed.

Hello Erinniog,

If you set up your Mac with Bootcamp to install a recent Windows 10, then yes.

But you can't run Game Pass PC/Ultimate on MacOS natively. You will need Windows 10 running on your Mac.
