My friend downloaded and installed Lion Server onto my MacBook Air. I don't see any purpose to running a notebook as a server. I have two questions: 1) Is there a performance penalty to have Server installed, if it isn't configured to do anything? 2) Can I uninstall it? If so, how? About This Mac reports the OS as being Lion Server, so I assume I can't simply drag the server icon from the Applications folder to the trash. Thanks you in advance!
