iPhone connects and disconnects from Mac

Hey guys,

I wrote a small .sh file (a .command, really) to address this issue. It works great. See here:

Thanks,

This is most annoying. I'm having these issues with a USB connection between iPad or iPhone connecting to iMac. Only solution is to force quit USBD from Activity monitor (or terminal method). This solves it while iPad or iPhone is connected. Once devices are disconnected, this will happen all over again when next plugged in.

When force quitting USBD and as an indicator that things are not right when plugging in device afresh, device constantly asks me to enter PIN number to trust device...

It's not - energy based (ie battery less than 60%)

It's not - a cable issue

It's not - Reset Location & Privacy settings on iPhone or iPad

It's not USB port on iMac - others have same results

Because it doesn't happen with same devices and cables at all when I connect iPhone or iPad to MacBook Pro.

Restarting iMac doesn't help either.

Any ideas what can be done here?

Thanks

I've had this problem for ages and finally found a solution.

On my iMac I went to - System Preferences - Network - iPhone

step1. untick disable unless needed

step 2. press on Set Up Bluetooth Tethering and turn bluetooth OFF.

Finally press apply.

Hope this works for you!

I also had this problem for a long time but trying solutions posted so far such as stopping usbd only worked sometimes. I now have the suspicious the root cause might be that this rapid connect/disconnect only happens when the iPhone is <100% charged so that the iPhone is using the USB connection with PC/laptop to charge itself while trying to use is as real communication link at the same time. Bringing the iPhone 100% charged seems to work OK although the link still flips a few times before settling down. Best would be if anyone knows how to stop the USB connection being used for charging temporarily from PC/laptop or iPhone side.

Actually,

sudo killall -STOP -c usbd

is also only a temporary fix

🤬

This worked for me. I charged it to 85% and problem is gone!

@apple won't fix it because it's coding they put on purpose to sell more phones. The coding affects the charging cycle and adds the count of your charging cycle. so not only does it damage your battery but it also affects your cycle count to void your warranty. This code is not accidental!!! I've used Apple for about 20 years now (before they were main stream). They have sold out. They more and more are obviously focusing on the all mighty dollar and raping their loyal followers. Shame on you Apple, I'd ask how you sleep but this is nothing compared to the slave labour and it's easy to sleep in beautiful homes that our money pays for.

thisisyouranswer was the answer I needed. It was hard to get to with the phone grabbing iphoto over and over but I got it eventually

I have the same issue. I have an iPhoneX and a Macbook Air. Whenever I plug in my device just to charge it while I'm using my Mac, a prompt appears telling me to install an update on my iPhone X, when I click "Install" a pop up appears telling me the software is not available. Then it disconnects my iPhone and hence, no longer charging it. But with my old iPhone 5 I don't have an issue such as this one. I already messaged their tech support and provided screenshots but still no solution until now.

I have been suffering with this issue since I got the MacBook, I chose to avoid the problem by using my windows 10 laptop but I want to use the photos app as my iPhone X 256GB is full! has anyone got an actual solution for this as the ones I've tried on here will not work. We don't have an apple shop here in New Zealand so it's difficult to get it looked at.

Thanks,

John.

The thing is, I am using Apple cables, and other i-devices seem to be able to connect to my MacBook Air just fine. This also happened with a previous iPad that I had the same info in. The problem, for me, is that something is wrong with the internal software? (I’m guessing, since anything else works and after backing up my 2nd iPad doesn’t work).

Having the same issue. I've tried everything posted here and none of it resolved the issue. Just tried this my final hope and now I'm unable to even get to iTunes to accept. Phone keeps beeping and vibrating...so frustrating !

This is infuriating! I am doing a video project and I cant get my videos off of my iphone. tried all of the suggestions here. Im paying good money for this phone. Iphone Xr, 2016 macbook pro. Apple you get so much of my money. Im over it. Fix your crap apple. its become junk. outrageous. LEAVE APPLE PPL

After trying all of these and having some temporary success, this seems to have worked, but I won't really believe it for a few days when I see if it comes back or not. But so far, so good. I did have to manually enter the IP address, which I copied from the Wifi information on the Network screen. Crossing my fingers.

This solution did the trick for me. iPhone 7 and Macbook Pro, both with the latest version IOS13. My battery charging is still a little wonky, but I am happy that Photos is not opening and closing in an endless loop! Thanks.....la3
