USB connection problem with iPhone
I have a MacBook Air Early 2015 and an iPhone 5s.
When I plug my iPhone into system my iPhone oscillates connecting and disconnecting rapidly.
I did almost everything: changed the cable, cleaned the dock, SMC, NVRAM reset, iTunes reinstall, iPhone's hard reset and restore privacy settings, even did a clean Mac OS install but nothing changes.
With pen drives, MIDI controllers etc... the USB works properly, and it does with my iPhone if I do not log-in into my Mac, just turning it on and plug the USB in. In that case there is no disconnect/reconnect cycling problem. But, immediately after I log-in it starts up.
I was in two different Apple Service and they said that is something software problem and possibly, a clean Mac reinstall solves it. It did not solved it! I tried to connect my iPhone into other notebooks, there were no problem.
Any idea? (Sorry for my poor English...) And yes, the cable is original.
Это хороший вопрос?
What is the MacOS version you are running presently and did you have any issues with your system before? Did it get wet or have something spilled into it?
Also, is the cable you are now using an original Apple cable? Some third-party ones don't allow enough power through and therefore demonstrate this problem.
Thanks for the answers!
I am running MacOS High Sierra at the moment, but before the update, Sierra did the same thing... I have no other issues before and Mac never got any wet.
The cable is absolutely original, I tried a few other cables too, and bought a new one just because of that symptom. I read a lot about that problem on the internet, many other users all around the World has the same problem but no one has the solution. (not just with iPhones, some iPads do the same thing...)
