Hacks of Macs, Microsoft Cortana are two more reasons why you should install updates

LAS VEGAS--Complexity is the enemy of security, but prompt patching is its strongest ally. Security professionals have made those points for years, but two presentations at the Black Hat USA conference here provided fresh arguments for them--and signs companies are getting snappier at fixing vulnerabilities. What that means for you: When your computer, phone or tablet says it has an update available, install it. Don't wait to benefit from the tighter focus of an Apple, Google or Microsoft on security issues. Support for that came in one Black Hat briefing covering a "vuln" in Apple's device-management system that lets organizations configure Macs from afar.
