Installation failed: Can't install the software

Thanks for explaining.

Which version of OS X or macOS are you running on your mac?

Which version of iTunes?

Since you are using an iPhone 8, I am sure you are running some version of iOS 11, right? (Only other possibility might be you are running a BETA of iOS 12).

Same issue here and, I had a support technician with me, on chat, when it happened. I was trying to perform an action with my iPad. Same situation and, the support technician couldn't do anything about it. Pretty sad situation when you can't even get a technician who can fix a problem.

Just updated to the new iOS 12. Latest OS. How is this still a problem?? Impacting greatly with my workflow as I mirror my designs to my device, with which this problem intermittently connects and disconnects. Almost impossible to continue like this... Sort it out guys.

so Ive scoured the help and nothing. Apple seems mute on this - its not acceptable and it looks like over 300 people have this issue. Apple stop counting your stock options and spend some of your zillions looking after your customers if you want to keep them...

The cable solution did not work for me, I tried both lightning cables that I own but the result is the same. I started out on OS Sierra, then upgraded to High Sierra and then to Mojave. It doesn't work with any of these operating systems. Pretty annoyed, I had no trouble a couple of months ago when I last synced my ipad.

Look back at the post in this series by rbcmsa....something like that. Anyways, they are pictures of the exact same dialog boxes that appear when I am in itunes trying to update an ipad. The ipad recovery process is crap. You can't go back and, you can't always get the 2gig download without three tries. Then, everytime you think you may have bricked your ipad after four tries of updating, the sixth try works. Yes, sixth.

If I ask the imac to go looking for updates, everything is current. So again back to the original post....What is this update?

Oh man! That's crazy. I was having the same problem with the software pop up that wouldn't install and the phone would sort of register in the Photos app then disappear and not show up at all in iTunes. So I tried a new cable like you suggested and sure enough it's working fine again. Thanks so much!

Well, here we are (see date/time of this post), and I'm also having this problem. Specs: iPhone 6S running iOS 11.4.1, 2015 MacBook Pro running macOS Mojave 10.14.1.

Before I address the "date and time preferences", I want to also add that while all the above mentioned alerts are happening, the electrical connection to the iPhone is rapidly toggling on and off. That's gotta be good for the battery (obvious sarcasm). That doesn't happen when I plug anything else into the USB ports.

The only thing that's different about my date/time settings between the devices is the city, but otherwise, everything else is the same.

An iPad cable, as opposed to an ordinary lightning iPhone cable … what will they think of next!

Well, here's what I discovered to do the trick: plugging in through my Mophee Juice Pack, the solution I would've thought least likely.

BDAqua, Thank you! I couldn't figure out how to indicate that!!! But yes, following those steps, my iPhone shows in my system info under the USB (as per the Apple article, it wasn't showing!), and works normally now!

What "new software" is this, exactly? ... Who knows? The dialog box appears when my iPad is connected to the iMac via an Apple USB/Thunderbolt cable. The dialog box looks like this... The first message just suddenly pops up. If you accept the update the second appears then eventually the last dialog appears when the systems cannot find the software.

So to answer your question. It looks like it is a system update, but since both my mac and iPad are up to date, it would appear to be an issue caused by Apple.

Would it charge if it were a powered hub instead? I'm waiting for mine in the mail to test. The problem started again to me after a few hours of smooth sailing. Now I switched to the other usb port and it started working again. It's not very reliable...

Stopped working as I was sending the post.

So, no, I haven't solved the problem as I thought. It seemed solved for a few hours...

I tried two third party ones and they didn't change anything. What changed things temporarily was turning off computer backups. Now it connects and disconnects randomly - worked for some hours and then the issue again. Waiting for my USB hub to arrive hoping it will make it work. Figuring out exactly what's going on would be nice. But there's even developers with this issue who don't know, apparently it's a bug.

This seriously needs to get fixed. I'm so annoyed everytime that I want to add music to my phone I have to sit and wait about 10 minutes for my phone to finally connect to iTunes before I can. I have disabled 3rd party security software, reset privacy settings, synched up date/time, etc. and NOTHING has fixed this issue.

It's been a while for this post, just thought to share my experience, yesterday i had a call with Apple support with same issue. Yes, it started with new apple iphone Xs original boxed USB cable. I thought it was the cable for a while and when i switched back to my old iphone X cable it worked (I was able to connect my iphone to my Mac Book). Apple also, told me to charge your phone to at least 80% with the power plug and try with the new USB cable of Xs. Once i charged it to 80% it worked with my new USB Xs cable. Weird, because if you connect iphone to Mac it should charge as well. Looks like the new USB cable of iphone xs needs to be charged using wired power plug and then it connects to the Mac book. Hope this helps.

Florencio.
