Apple forums alive and well

I have brought in an old iphone and validated that the old iphone works on my laptop. To make this clear. The problem is between iphone 1 and mac 1. However, iphone 1 works with mac 2, and iphone 2 works with mac 1, but iphone 1 doesn't work with mac 1. So it is specifically between those two devices that the problem lies.

My iPhone is on iOS 17, xCode 15.1, and just upgraded my laptop to macOS Sonoma, and I'm still having this problem. XCode doesn't even recognize my iPhone. I've tried clearing trusted computers, restarting everything, different USBC ports, nothing is working!
