Project:MSP430 Mac Howto
From London Hackspace Wiki
This page documents Flux's attempt to get the TI LaunchPad working on a MacBook Air running Mac OS X Lion 10.7.2. This is in preparation for development of HackSat1.
After trying to get GCC compiled for a couple of hours I cam across http://osx-launchpad.blogspot.com - which just seems to work.
