I have OSX Standalone installed but doesnt work onLinux

I have OSX Standalone installed in Linux Unity 2019.2.6f1. It shows in the hub display. But the Build Settings doesn’t have a selection for it and I get this error when trying to build a bundle for it. Is there something I am missing?


Building an AssetBundle for target ‘MacStandaloneSupport’ is not allowed because the required module is not installed.
UnityEditor.BuildPipeline:BuildAssetBundles(String, AssetBundleBuild, BuildAssetBundleOptions, BuildTarget)
TilesetEditor:BuildBundle(TilesetAsset) (at Assets/Scripts/Editor/TilesetEditor.cs:340)
TilesetEditor:OnGUI() (at Assets/Scripts/Editor/TilesetEditor.cs:169)
UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

Answer is here;
