Macbookではハードウェアで頂点処理できないっぽい

                device = new Device(0, DeviceType.Hardware, this, 
                    CreateFlags.SoftwareVertexProcessing, // softwareで頂点処理
                    presentParam);

あと頂点形式をCustomVertex.PositionColoredじゃなくてCustomVertex.TransformedColordにしててMatrix変換が適応できなくて間違ってた。
