Security News > 2020 > January > Apple patches critical bugs on iPhone and Mac – update now!
Apple has just announced its latest round of security updates.
There are plenty of critical holes patched in this raft of updates - so we strongly advise you to patch right away, before anyone figures out how to abuse these newly-documented holes for fun or profit.
A newsworthy change that arrived in iOS 13.3.1, but that Apple didn't count as a security fix, is listed on Apple's general About iOS 13 Updates page.
On an iPhone or iPad, go to Settings > General > Software Update.
On a Mac, go to the Apple menu, choose About This Mac and click Software Update.
