It is really incredible that there are hundreds and hundreds of users that face the same problem and the fact that one user solves by one method and another solves in other one but most of the does not resolve at all is not normal at all. Yesterday magically at a certain moment I was able to connect Mac and iPhone and deposited my programme on the phone. I have restarted completely the phone to factory settings and now there is no way to get connection between Mac and iPhone. It remains eternally in Prteparingfor development . Would it be possible to get from Apple a definitive solution for this long lasting issue ? Thanks
