Installation failed: Can't install the software

I had this problem only if I open iTunes manually and after that connecting the iPhone X. What solved the problem for me was to have iTunes closed, then connect the iPhone. iTunes will opens automatically and recognize the iPhone. No software to be downloaded then.

I had this problem for months. I have a iPhone 7 plus and a Mac (High Sierra). When I upgraded to Mojave the problem still exists. The time and date settings were the same and changing to other USB ports or Apple cables did not help. I finally solved the connection problem via a very cheap non Apple cable between my iPhone and Mac. Now iTunes made a backup and is downloading the needed software for my phone.

If you can live with not syncing over the cable and just want to kill the popup and allow charging, then this seems to have worked for me 🤞

Simply check the "Prevent iPods... syncing automatically" box.

Hi,

I had the same problem with my iPhone XS.

I was using an older lighting cable from an SE which resulted in the same problem.

I then switched the cable and plugged in the new lighting cable which came with the XS (I was saving it till the old one broke) so the solution may be as simple as finding a new cable.

Hope this works for everyone else!

Happens when I try to sync an iPad Pro to a MacBook Pro 15 2015. After a reset in safe mode and back to normal, it actually worked normally for a few minutes, and then the dreaded pop up asking me to install software that doesn't want to install appeared.

I tried a third party lightning cable I have, no difference. I could order another official Apple lightning cable and see if it makes a difference, but I'm not sure that's the issue.

I tried all other suggested resets to no avail. I also installed the latest Xcode - nothing changed. Very weird that it worked for a few minutes, I could access the iPad, sync and charge. Feels like a software issue to me. I have the latest MacOS and iOS.

**FIXED MY PROBLEM**

I have a MacBook Pro macOS Mojave version 10.14.2, iTunes version 12.9.2.5, iPad Air 2 iOS version 12.1.1, all UTD.

• I tried signing out of my iTunes account and signing back in. Did not work.
• I downloaded Xcode through the Apple App Store and started it. Did not work.
• I updated my date/time on the computer. Did not work.
• I attached my iPad to my MacBook using multiple different USB cables, both official Apple and Apple approved. Did not work.
• I attached my iPad to a USB cable to an unpowered 4-port USB hub, which is then attached via USB to my MacBook. This DID work. However, my iPad will not charge via this link. BUT now I can at least back up and sync my iPad.

Thanks for the tip about upgrading Xcode. I did that, then had to wait for the "trust - don't trust" message to flash on my phone. The message would come up and disappear as my phone disconnected (and re-connected) itself. I had to wait for the message to come again and pounce on it like I was playing a video game!

It makes me feel like I'm using some flimsy third-rate bootleg software.

This is such help! Just did what you said and it worked 🙂 🙂 🙂

I have this, there is no package called MobileDeviceUpdater. Any suggestions? Tnx 🙂

Un update: switching cables work. This is unbelivable....I was using a cable for Iphone 6, and I obviously have to use un iphone 8 one.....

try those two resets guys

Switching to a different lightning cable worked for me. I was using a high quality cable but still had this problem until I switched to a different cable.

You have to use a new USB lightning cable. Once I used the new cable that came with the new iPhone, and restarted the macbook air, it worked.

Sorry, how do I disable it? Where?

Dont know about sizing but I do know that only the cable that came with the phone would work with iTunes and my X phone.
