iTunes does not even show the iPad as connected. Using the other method, iPad comes up on iMac, asks to trust, iPad asks trust and waits. Then continued cycling until imac says request denied. Have been following all recommendations for about a year - no go.
iPad Air 2, iOS 12

What version of Mac OS is installed on your iMac? It must be very very old as iTunes was replaced years ago now. Please read Writing an effective Apple Support Communities Question in order to help you and then consider re-writing your post with information that will help you solve your problem.
Thank you den.thed, Your information was helpful and informative. I followed all suggestions but I believe that my iMac is just too old. It is late 2013 model w Catalina 10.15.7 macOS. It will not trust either my phone or iPad Air, just cycle's.
