A new beta version of the software V4.1.426 has been released https://www.silhouetteamerica.com/software Have been testing it for a while and there are quite a few improvements including Bluetooth, I don't use Bluetooth much but when I do it works fine but I am on Windows and I think it was Mac users who had more problems. You can find the release notes here. https://www.silhouetteamerica.com/so...ease-notes/610
