Here is the scenario. Say I have a Mac that I have to leave in a semi publicly accessible location and which I need to be awake at all times (i.e. it has to be accessible and not asleep/locked). I want to have this Mac logged in to my iCloud account, but only for the point of Find my Mac. So if it walks away, I can at least wipe/lock it, if not actually track it down.
But alas, while I want this one iCloud feature, I don't want any others. I can leave them unchecked of course. But I want to prevent someone who might steal this computer, from being able to access my contacts, calendars and photo stream just by checkin a few checkboxes. But unfortunately there is no padlock on the bottom of the iCloud System Preferences pane.
Is there any solution to this?
