iMac won't backup iPhone 11
As of yesterday my iPhone 11 won't backup to my iMac, although it has always done so successfully before. I got an error message saying that the backup won't work without an update. I loaded and installed the update but there was no change in behavior. The iMac is running MacOS12.6 and the iPhone is running iOS 16.0. I also she down and rebooted both the iMac and the iPhone, to no effect.
Any suggestions? Is this a bug or a malware result?
