Apple Updates showing as 'No Updates Available' after reverting to Apple's server

[May]

I'm testing switching back to Apple's update servers from our own in house one.

I've removed the configuration profile that was pointing the machine to our catalogurl, run softwareupdate -l and it lists the available updates from Apple's server

ran sudo jamf removeSWUSettings

check that the catalog url has been removed with this EA which returns 'None'

#!/usr/bin/python

# EA to show if Software Updates are managed or not

import CoreFoundation

domain = 'com.apple.SoftwareUpdate'
key = 'CatalogURL'

key_value = CoreFoundation.CFPreferencesCopyAppValue(key, domain)

print "<result>{}</result>".format(key_value)

then run recon on the machine, when i check on the JSS the computer record shows Software Updates as 'No Updates Available'

any ideas what i'm missing ?

u generally need to reboot for changes to the com.apple.softwareupdate.plist file to take effect.

When I perform a check for updates manually High Sierra doesn't come up. I had to go to featured and type it in to download it. Hope this helps. Adam

thanks @ooshnoo @dwillis

i've restarted and it still shows 'No Updates Available', the odd behavior i've just noticed is if i connect the VPN then run recon the updates show up in the JSS, if i run recon whilst off the VPN it shows 'No Updates Available',

This is the expected behavior we see when a Mac is pointing to our in house update server as they can't reach it whilst off the VPN, to make sure it's not still using that catalogurl i turned off the in house update server and ran softwareupdate -l and it still lists updates on the Mac, plus some of the updates that are listed using softwareupdate -l are not enabled on our own server so i'm pretty certain it's not trying to use that.

ok, after deleting /Library/Preferences/com.apple.SoftwareUpdate.plist it now shows the updates in the JSS all the time.
