Reality check
There is no official macOS build. CrossOver can launch the game for local testing, but EOS multiplayer auth often fails on Apple Silicon.
CrossOver launch workaround
Steam launch options (skip broken launcher check):
-dx11 -windowed -ResX=1280 -ResY=720
Point Steam to Shipping executable if Visual C++ prerequisite loop appears.
Intel Mac
Boot Camp + Windows 10 is the only reliable way to play online with friends.
Honest recommendation
For serious multiplayer, use a Windows PC or cloud gaming PC service. Do not expect stable invites on CrossOver.
