Hi I've been buried in Second Life for a year now. I am a builder, DJ and avid Mac user. If you need help, let me know I'll be happy to help out. I especially have experience in world and RL with Mac Book Pros. My primary system is a MBP Core Duo 15", and I've used a MBP Core 2 Duo 17".
If you have questions about OS X 10.4.x (Tiger) or 10.5.x (Leopard) drop me a notecard, or try IMing me in world, more then likely I can help.
Want to know how to DJ using your Mac? I can walk you through setting up the easiest system, using Nicecast and iTunes, or more complex means, such as using SAM Broadcaster in Parallels.
