I just got a new Macbook pro but when I plug my iPhone 5s into the USB to sync, the iPhone keeps making the charging sound by constantly beeping. therefor iTunes cannot connect to my iPhone. The iPhone behaves normally on my old Mac and when charging in a socket.....Any ideas? Turning the phone off doesn't help nor does restarting the new Mac.... Thanks!

Colt, find a reliable solution from Apple support?
My 5s recently started causing iPhone "Unknown Error -50" when plugged. Repetitive beeping as the phone connects/disconnects to an Apple refurb'd MBP Mid-2015. Both phone and Mac sw up to date. And, whether connecting via USB3 ports or WiFi. Same result with either USB port, and with different USB cables. Also, when it's working, it doesn't matter which port or cable.
It started this several months after I got the new MBP, so guessing it's a software issue introduced with one of the several iOS and macOS updates.
Sometimes it has worked after a Mac and/or iPhone re-boot, sometimes just re-starting iTunes, sometimes some other particular combo of power-on/off, connect, or re-boot sequence... or some other variable. Never found a repeatable procedure. Guessing Apple hasn't either. ; >)
Try a different USB port. Or another cable.
If it is continuously connecting and disconnecting, there could be a hardware issue on the MacBook Pro or the cable.
Thank you. The macbook is brand new, I just got it and this beeping occurred the very first time I hooked up the iPhone The iPhone doesn't do this when attached to the old Mac or to a normal wall socket.....So it can't be the cable and it should definitely not be the macbook! any other suggestions? Thanks again!
If it is a problem with the usb, you could do a pram reset. https://support.apple.com/kb/PH18761?locale=en_US Are you using any kind of an adapter for the phone for usb 3? You also have 90 days of free online or phone tech support you can use. https://www.apple.com/support/contact/
thank you. no I'm not using any adapter..... is just so weird! thanks very much!
If could be an incapability of the cable or your IOS. But I would call apple.
Reset the SMC on the computer. This reroutes power to your hardware. Just make sure everything is disconnected except the Magsafe power adapter.
Have you tried using any other USB devices on this new computer?
Yes it is brand new, but it can still have a hardware problem if something went wrong during manufacturing.
Resetting the System Management Controller (SMC) on your Mac - Apple Support
thank you, Yes I've used an external harddisk and that's fine..... so that should rule hardware power problem out right? thx
I want to say it does, but if your iPhone connects to another computer with the same cable without an issue, then the only logical explanation is the USB port on your computer.
Here's what I would do:
1. Reset the SMC using the article I posted
2. Restart the iPhone by pressing and holding the power and home button for 7 seconds
3. Connect the iPhone using only Apple products, no third party cables
4. Connect directly to the computer, no USB hubs or extensions
After that, If you still have the problem you may want to seek the help of the Apple Store. I would bring your computer, iPhone, and cables
Many thanks, I am going to try it later tonight! I tried hooking up my daughter's iPhone and the same beeping noise came up so it definitely is something with the Mac! Thank you so much for taking the time to reply!
Hello there - I'm having exact same issue with macbook pro and iPhone 5s. Let me know how you make out. I talked with apple rep and they said to try a different usb cable. The one I'm using came with the iPhone and I tried it in both usb slots with same beeping results. I've been able to bring over a number of my windows files on a usb stick with no problems as long as I eject the usb stick each time. The cable charges the phone with no prob's. My wife got the same phone so I will try her cable later today.
fyi no difference with the other cable.
Good luck! My daughters iPhone had the same issue! And so did my husbands. I tried the SMC trick but that did.t help...... I will phone Apple support tomorrow. I also have a problem with the Migration Assistant that cannot connect to my old Macbook and I also have a problem with migrating Photos (all the photos are there on my new Macbook but I've lost all events, albums and faces....... I will keep you posted. Hope you resolve your problems. Ciao
Thanks! Tries the SMC trick but to no avail. I have a 90 day free service thingy so will call Apple support tomorrow. I'll keep you posted!
