Supporting Code Composer Studio on Mac has been one of the most common, if not the most common, request we have had from users on the E2E forums. It has been a long journey but we now have a beta version of Code Composer Studio supporting MSP430 microcontrollers available for anyone to try. This release is based off of CCSv6.1.0 which we recently released for Windows and Linux platforms.
Similar to our Linux version of Code Composer Studio there are some limitations on the debug interfaces that you can use. The MSP430 USB FET works fine, as do newer LaunchPads such as MSP-EXP430F5529LP and MSP-EXP430FR5969. However older development kits like MSP-EXP430G2, eZ430 and Chronos are not supported.
You can download the beta version here. (Updated link to beta 3, Dec 2015)
We plan to add support for more device families throughout the year.
Note that when running CCS you will notice that it mentions 30 days remaining on the license at the bottom. This can be ignored, there is no time limit on the license.
Please post any feedback that you have to the E2E forums. Supporting Mac is new to us and value any feedback that you may have on how we can improve out support for Mac users.
