My school is running a 2009 Xserve as the server for our Mac suite, and when I took over maintaining it I was told that it needed to be restarted each week after updating the software. Said update was always an EFI firmware update, and I always thought it odd that Apple released a new one every week without fail. Eventually I noticed that the version number was the same each time (1.2), an update that I believe dates back to 2010, and that basically the update isn't sticking. We've had various issues with this server, most notably that users are often unable to log on or their home folders cannot be found when they do log on, and applying this update then restarting has been the appreciated way of dealing with such problems amongst those who use the Macs since before I started. This makes little sense to me if the update isn't actually taking, and I think it's the restart which is addressing these issues, if only temporarily each time as we seem to have a new clutch of problems each week. Is there any way to address this? To actually install the update properly and hopefully solve these login/home folder issues? We're running the latest version of OS X Server Leopard, and all machines are on the latest version of Leopard if that helps.
