Base game Order of Battle on Mac

[Fedem]

Hi,

I used to have the game and almost all DLCS on my previous Mac Bro.

Now i had to change to a Mac Air and can`t find an installer for Mac.

Any way to install it or it`s impossible even as in the store says it runs on both systems. I know the game doesn`t have any more support for MAC but even some bundles are for sale for both systems.

Many thanks for the help!
