Not sure what changed, but I loaded NetSUS 4.0.0 VM again and ran the sync
overnight and everything looks fine now.

Thanks
Dave

hi; @dforman
Can you see the last mac os x updates ( 10.11.3.or 10.11.4 ) on the NetSUS 4.0.0 also which url are you using for El-capitan Osx ?
Thank you

Thanks for the reply

The latest update is:
OS X El Capitan Update version 10.11.4 date 2016-04-11

Not sure why but there are 3 listed and I have a number of updates that have double listing
like Safari 9.1

I am using the default URLs
