1) You must install Xcode (from link below or the App Store):
http://developer.apple.com/technologies/tools/xcode.html
(you won't be using the Xcode interface directly, QB64 just needs to have access to the MacOSX C++ compiler it installs)
2) If using MacOSX 'Lion' or above, you must also install XCode's Command Line Tools. These can be installed from within Xcode in 'Preferences', then 'Downloads', then 'Components' and then clicking 'Install' in the line with the 'Command Line Tools'.
3) Extract the QB64 download and run 'setup_osx.command' located in the 'qb64' folder.
