That was my first thought, but we have a requirement that the value persist across installs, and I don't like leaving a preference file behind on uninstalls. So, using one or more of these values seems to be the best solutions. I'm just trying to find out if Apple is moving away from Mac addresses for this purpose. With no real documentation on the IOPlatformUUID value I think I will use a combination of the Mac address and serial number a unique ID string. I may factor in the IOPlatformUUID value if for some reason the serial number is missing. It still isn't clear wether you are interested in tracking a very precise piece of hardware or a very precise registration against a server (whatever it is, since you didn't tell anything about it). Unless I'm wrong, these could be very different things. Could you elaborate? This email sent to site_archiver@lists.apple.com
