When you try to connect a new iPad (iPad Air, 3rd generation) running 13.3 to an old iMac running MacOS 10.11.6, the iPad / computer connection (via cable) never succeeds.
All prompts are correctly followed:
Trust this computer is selected.
Do you want to allow this computer to access this iPad?
The access code is entered correctly on the iPad.
Then the computer hangs when prompted
To allow access, please respond on your iPad...
… until expiration with a response from
iTunes could not connect to this ipad. You do not have permission.
What's wrong? Has Apple deliberately banned the use of old computers / MacOS with newer devices ??
