With the recent release of iOS and iPad OS 18, we are performing compatibility testing between Tablet Command, TC Mobile and iOS/iPadOS 18 to ensure that everything is working smoothly. We will notify you with an "all-clear" when testing is completed.  In the meantime we recommend holding off on updating any mission critical devices running Tablet Command or TC Mobile to iOS 18 at least until we have completed testing and given the "all-clear".
