I'm in the same boat as you on the lights and dull/washed out colors. I was using the app and running VMware so that I could run it on windows. I finally signed up for the browser beta and installed the connection manager for Mac. I ended up picking some enhancing template they had and put the whole thing at 75%. I'm not 100% happy with it but wasted enough time already. I'm waiting on a bigger skimmer and dosed a few things after reading up on how to enhance color.
As for LiveAquaria, I saw they had the Naso tangs on sale so I got a few people together locally to go in and get free shipping. Let's hope it all works out tomorrow.
... and someone call the tang police because I'm going to offend everyone here
