OS 10.7 I know this may be a possible touchy issue. it apparently is on apple support. I admin a number of lab machines including macs. I use a mac server for all updates. What I would like to do is find a way to have system updates automatically install regardless if anyone is logged in. All labs are closed at certain times to allow things like this. I looked at ard and I didn't see what I was looking for. I do not really want to create packages every month. I would just like 10.7 to go out at a certain time and pull updates from my server and install them with no user interaction. if this is possible, great! if not, well I figure something else out. If no person in their right mind would do this, explain why so I know. Thanks!
