Man alive, I have tried and tried with my new iPhone 15+ to get it to physically sync with my iMac (iMac (Retina 5K, 27-inch, Late 2015 3.2 GHz Quad-Core Intel Core i5). The phone charges when plugged in via USB (I have tried other cables and USB ports) but it just will not show up anywhere. Nothing in the Finder or any apps. The Apple forums suggestions were of no help and did not work. I'm stymied at this point. Anyone have any clues? Can't even get the phone to be seen by apps like Waltr.
