NEW YORK (AP) — Apple’s latest security update was easy to miss. But security experts are warning that everyone should update any Apple device they have immediately. Apple said Wednesday that there are serious security vulnerabilities for iPhones, iPads and Macs that could potentially allow attackers to take complete control of these devices, and that the issue may already have been “actively exploited.” Apple’s security updates happen multiple times a year. The bad news is the vulnerability means a hacker could get complete to Apple devices. The good news? There’s an easy fix by clicking “Software Update” on your Apple phone, computer or tablet.
