I will still give the instructions for manual updates because while automatic updates should be the norm, I know I will meet with one of you a couple weeks from now who — for some reason — does not have the newest updates

Both the iOS update and the Mac OS update released today are STABILITY AND SECURITY FIXES. 

1.  To get iOS 10.3.3

– Make sure you are on WiFi

– Settings

– General

– Software Update

– Download and Install

– After downloading  – Update Now

2.  To get Mac OS 10.12.6 (I think Mac is not capitalized anymore.  Oh well!)

–  Apple Menu 

– App Store

– Click on the Updates button once the App Store opens

– Click on the Update button next to the Mac OS update (or Update All if there are multiple updates)
