I know where is the bug now.

In the Vuforia.UnityExtensions.Editor.dll, there is a class named PostProcessBuildPlayer in the namespace Vuforia.EditorClasses.

There's a line hard code like below. The bug is caused by it.

private static void ProcessPbxProj(string xCodeProjFileName, PostProcessBuildPlayer.Framework[] frameworks, PostProcessBuildPlayer.ResFile[] resFiles)

{

                    //...

                    streamWriter.BaseStream.Seek(-3L, SeekOrigin.Current);

                    //...

}

The bug is caused by the NewLine of win and mac is different. It should be coded like this instead.

streamWriter.BaseStream.Seek(-2L - (long)Environment.NewLine.Length, SeekOrigin.Current);

Please fix it in the next version.
