While setting up my Macbook Pro for web development, I was flummoxed by the issues reported by many people trying to setup ColdFusion 10 on OSX 10.8 Mountain Lion, as well as Window 8. Adobe even has a pre-release program to test new installers for both. I can understand having problems with Windows 8, but installing on OSX 10.8 couldn't have been easier.
I recently picked up a 17" Macbook Pro and am in the process of setting it up as my primary development machine. I'm a long time user of Eclipse and moved from CFEclipse to ColdFusion Builder when version 2 arrived. I've heard a number of users complain about performance. Other than opening massive legacy files that contain thousands of lines of code, I haven't had many issues myself. The trick is to not install CF Builder as a stand-alone IDE. Here's why and how.
