This is probably fine for a home network, but not on a corporate network. I googled like crazy and all the solutions I found suggested that I should turn off Wake for network access altogether (Fig 1) to get rid of this random wake up-problem. Obviously, no one was present at the computer at that time. Nov 26 00:22:55 xxxxx kernel: Wake reason: RTC (Alarm) If you investigate the system log it won’t give you that much information about the random wake-ups: No such option exist in Mavericks, and I only want to wake up the computers with a magic packet sent from LAN (and by me). This behavior has apparently changed from OS X Snow Leopard, where you had the option to just enable or disable Wake on LAN. This will not be good for the hardware either. This is a bad thing, as I DO NOT want the computers waking up every second hour or so for no specific reason. It turned out that the “Wake for network access” feature in Energy saver wake up the computers at random, not only by a magic packet or remote login. However, when I was trying to come up with a decent solution for managing/connecting to them remotely I ran into some problems. They are all joined to Active Directory domain and working just fine.
I recently installed a Mac classroom with eight 27” iMac’s.
