Hello,
I have a script which points our Yosemite Macs at the correct NetSUS and Branch for each of our locations. We are using the JAMF NetSUS.
After running the script, the /Library/Preferences/com.apple.SoftwareUpdate.plist is indeed pointing to the correct NetSUS and branch but the minute I run the softwareupdate -l command the plist changes and the Catalog URL is wiped out. Has anyone seen this behavior?
