iMac won't Trust iPhone
I'm trying to back up my iPhone X to my iMac before I upgrade to my new iPhone 12 but, after going through the "trust this device" sequence, my iMac won't deliver the code I'm supposed to enter on my iPhone. It just times out. 😕. I've restarted both computer and iPhone and I've reset Network and Privacy settings on the iPhone, to no avail. Any help would be appreciated.
