I'm looking for some advice on the best way to manage 6 Apple Mac's that we have ended up having on our Windows network. We've just recieved a new 27" i5 iMac with OS X Lion installed on it and there is an update available for iPhoto via the App Store (it's not listed in the Software Update option. To download the update I need to configure an Apple ID. We have another Mac that has OS X Leopard installed on it and we'd like to get that on to Leopard (the idea being that if all our Mac's have the same version of the OS on them it'll make is easier for us to support). To do that I need to upgrade to Snow Leopard and then download OS X Lion via the App Store. Do I need an individual Apple ID for each Mac? If so what's the best way of us (the IT Department) of managing these accounts? I've looked at Apple Volume Licensing but that's only available for 20+ Apple Mac's. What's the best way of managing/looking after the Macs that we have with regards to Apple ID's?
