continuous beeping sound when plugged into iMac

When back up my iPad to my iMac, I get a continuous beeping sound showing charging/not charging. Why is this happening? It does not do it while plugged into the wall. Only when plugged into iMac. iTunes not recognizing device.

Hello Ghee_Ghee,

If you're hearing a continuous beeping sound then it's likely that your iPad doesn't have a stable connection to your Mac. While there may not be an explicit alert, the article linked below details a number of steps that can help stabilize the connection between your iPad and your iMac.

This did not help, any other suggestions please?

Ghee_Ghee,

Thank you for using the Apple Support Community. Due to the nature of your issue or question you may find more information by using another one of Apple's support resources - https://getsupport.apple.com/GetproductgroupList.action.

All my best.

I had this problem too but after extensive testing this morning (multiple laptops, iPads, iPhones, ghost disk backups, etc.) it turned out to be my lighting cable.  Strange because the cable works fine for many things but no longer works with my iPad. I got intermittent connections with iTunes that didn't last but for a few seconds.  Soon as I used another lightening cable the issue went away.

Might be worth a try.  Very frustrating I know. 

Way late for your issue (I hope), but I was having this issue with my iPhone SE and my (mid 2013) MacBook Air. I have the latest iOS installed (11.0.2), as well as latest macOS (10.13) and latest iTunes (12.7.0.166). The phone repeatedly dinged and would not stop. Tried various cables, etc. No luck. I turned off iCloud on the phone; still dinging.

Finally, I put the phone in Airplane Mode, and it connected fine to my Mac and iTunes -- first time -- no issues.

Weird and a PITA. Hopefully Apple fixes this in an upcoming update.

HTH someone.
