If you are writing code for your Arduino on a Mac and you've previously written code using Apple's FREE Xcode IDE, you know that the standard Arduino development environment is lacking in functionality, especially those which professional software developers have had in their IDEs for years. My personal favorite is Apple's Xcode IDE, which is the primary IDE used in developing applications for the OS X on the Mac and for iOS applications on Apple's mobile platforms (which are technically ALSO running Apple's OS X operating system). Find out how easy it is to use a professional-grade IDE to do your Arduino code using embedXcode from Rei Vilo Hobbies.
