I wasn't sure if this question would have been better suited for the Lion forum, but figured there's probably better expertise in this forum for this question. I recently got a new MacBook Air for work. It's going to be about a week before my network admin will be able to get to my office (he's remote) to join my MBA to the corporate Active Directory Domain. He asked me not to really do anything with my MBA until he can get me connected to the domain. He said to not install anything or do any customizations to it. My question is why? He admitted that he really doesn't know a lot about Macs, so I'm wondering if he's just being overly cautious because he just doesn't know any better or if there's really a valid reason why I shouldn't start setting things up in terms of installing Office 2011, OmniPlan, OmniGraffle, Firefox, etc before he can join me to the Active Directory domain?
