Hello Alan,

1. Did you install at some time Microsoft Power BI?
The Microsoft Power BI for iOS app on the iPhone, iPad, or iPod Touch delivers 
the mobile BI experience for Power BI, Power BI Report Server, and Reporting 
Services

2. Why This Alert Appears on Your Mac

Generally, if your Mac is running the latest macOS version and your iPhone is 
running the latest iOS version available, you should never see this message 
appear on your laptop or desktop's screen.

If your iPhone is running a newer version of iOS than the macOS version you're 
running currently supports, you will not be able to sync your iPhone with 
iTunes if you get the "software update is required to connect to your iPhone" 
alert. You will, however, still be able to charge your iPhone and use other 
tools such as Image Capture, Photos, etc.
How to Sync Your iPhone with iTunes Again
If you have no interest in updating your Mac to the newest macOS, the answer 
may be painfully obvious. When you see the "A software update is required to 
connect to your iOS device. Would you like to download and install this update 
now?" prompt, simply click on "Install" to update the software needed to get 
your iOS device working with iTunes again on an older macOS version.

Another solution would be to open up the App Store on your Mac, head to the 
"Updates" tab, then update any system software to the latest version. If you're 
currently running macOS Sierra or lower, it's a good idea to update to macOS 
High Sierra. Most third-party app developers have had ample time to make sure 
their apps work with High Sierra, so there should be no compatibility issues 
there.

Cheers,
Ronni
