Fresh DV links to a set of tips on how to set up your OS for best use of Final Cut. The list isn’t that incredibly useful, as most of the stuff you have to do just to use Final Cut appropriately in the first place and the other half is the default at install. I also agree with the Fresh DV author about the System Update comment. I think it’s worth leaving the System Update notification on automatic, just make sure you can pick and choose what to install.
