We always remove the hard drives when returning our computers to a service center - company policy. We now have a MacBook Pro that infiltrated our IT Department (mine! ) . My IT department wants to remove the hard drive, but I told them that this might cause trouble with the Apple warranty (same idea as upgrading drives ?) Anyway - just curious how other businesses handle this? I am going to call the service center about it, but they aren't open yet, and wanted to drop it off on my way in to work. Thanks!
