Security Update 2017-001 10.12.6 Problem- having problems with this update on my iMac. I keep seeing a message that the security update cannot be completed. After sever restarts and tries this is unresolved. Anyone having this issue and any tips
iTunes and Safari updates completed but I repeatedly get a message saying the Security update was not completed. I have restarted 5 times and the update keeps downloading and completing but i still get the same message. Is anyone else experiencing this issue and are there any suggestions on how to resolve.
This issue is on my mid-2011 27-inch iMac.
iMac, iOS 10.12.6
