I just found a really great app called gfxCardStatus that works with any 2008 or later MacBook Pro. It is a menu-bar app that shows you which GPU is currently being used. Keeping it down to the Intel GPU decreases the heat generated and increases battery life.
just got my Mac Book Pro Retina and without a doubt it is the best computer I’ve every owned. My vision is pretty crappy, and I can’t make out heads or tails on a MacBook Air screen at the default resolution (glasses make no difference). But the MBP retina display is so crisp and sharp that I can even read the text from a few feet away. I had really thought I’d never be able to comfortably view a laptop screen again. I got the 2.6 GHz model with 16GB RAM and a 512GB SSD. And it is a screamer. I ran geekbench on all of my current computers, and the numbers are impressive. All the older machines have a 256GB SSD in them.
Ben Brooks wrote about the problems with using Dropbox and multiple Macs, offering a solution using Keyboard Maestro. Here is the solution I’ve been using for a while. Save the following AppleScript and set it up as a Folder Action in your Dropbox on each machine (you must do it on both machines if you want it to work both ways).
Earlier today Xcode downloaded a documentation update for Lion. I didn’t think anything of it, until I needed to look up something. All of a sudden, none of my bookmarks in Xcode work!
