iPhone 7 on iOS 15 not showing in old iTunes

Hey there!

Thank you for updating us. It's great that you were able to test multiple computers with your iPhone. From here, we'd like to suggest that you install a specific version of iTunes, which is iTunes 12.8.2. The link for the update can be found below:

Download iTunes 12.8.3 for Mac

You'll see the option for that specific download listed at the bottom "10.11 and 10.12 users download iTunes 12.8.1 here". Click not he "here" in blue. Once the installation is complete, install any pending updates that might be available and test to see if that helps. If you continue to experience the same issue, you might want to consider reaching out to Apple Support for additional help. Just in case, you can use the link below to reach them:

You'll want to follow all the steps listed within this specific resource. It has great steps you can try. Feel free to keep us posted on your results. Cheers.

For iOS 14 you need iTunes 12.8.2.3 or better running on OS X 10.11.6 or better. See How to upgrade to OS X El Capitan - Apple Support if required. I think the same limitations apply to iOS 15.

Assuming a suitable version of iTunes is in place then in Finder use the menu item Go > Go to Folder..., copy the following text, paste it into the dialog box and press enter:

/System/Library/PrivateFrameworks/MobileDevice.framework/Versions/Current/Resources

Unlock your device and connect it to USB. Double click on MobileDeviceUpdater in the folder that has opened. It should notify you of a software update. Install it and iTunes should hopefully recognize your device.

If these steps haven't worked you can also try reinstalling iTunes12.8.2.3.dmg (El Capitan/Sierra) or iTunes12.8.3.1 (High Sierra) while your device is connected and unlocked.
