iTunes not registering iPhone update
All software is updated on both phone (7plus) and mac but when I plug phone in to iTunes on the Mac I get "To use your iPhone with iTunes, you need to install OS X 10.11.4 (or later)". It has OS X 12 on it. I have rebooted everything. Reinstalled iTunes on the Mac. Still nothing which means I can't use my iTunes or back up my phone because I can't get past this. Anyone have an idea how I can fix this please?
