ipad not connecting to iTunes
My iPad mini has synced via usb with iTunes numerous times in the past. Today, as soon as I connect the cable to both the iMac and the iPad, an alarm goes off on the ipad (even though sound is muted). It's a constant ding ding ding... No error messages on either the iMac or the iPad appear. I have viewed numerous threads in the community about failure to connect, alarms, ect and have not found one that is similar to my issue, so I thought I would ask the community if anyone has experienced this and more importantly, has any one resolved. I need to sync the device and offload some videos I recently made on the device to my iMac for further processing. Anyone have experience with this failure and resolution?
iPad (5th Generation) Software version 12.3.1
iMac Retina 5K, Late 2014 Software version 10.10.5
iTunes version 12.8.1.3
Thanks in advance.
iPad, 12
