Is there a way to do this? I tried to buy the client version of Lion from the App Store last night but it would not let me buy just the client. The App Store gave me a message saying that since I have a Mac Mini Server, I would need to purchase Lion Server to upgrade. You see, I bought the Mini Server for the hardware, not the server functionality. I don't need the server part and don't even know how to set it up. The client Lion on my Mini would be ideal if I can do it. Thanks for any feedback.
