Im trying to lock down the option for OS X 10.5 to automatically check
for software updates. I'm using MCX policy to tell the Macs which
server to use for the updates (I have my own SUS server on my LAN),
but there isnt a way to disable the OS X from automatically checking
for updates. I want to discourage users from seeing the "new software
is available" dialog pop up every time iTunes is updated, etc. "Out of
site, out of mind"
I tried these files, and none of them contain the key to disable
automatic checks for 10.5:
