Dear support folks, why don't your update your KinetisDesignStudio release notes to let people know that KDS does indeed work on MAC pyOCD debug?? The statement "Currently only the Segger debugger works on MAC OS X" is not true. See the fix posted on bed at: https://developer.mbed.org/forum/platform-38-FRDM-K64F-community/topic/17088/ here too http://www.thomasweldon.com/tpw/courses/embeddsp/frdmK64_kdsMacSetup.html
Thanks for providing the link to the installation instructions.
That statement refers to what is included and installed in KDS, and does not cover any other additional connections which could be added.
Thanks again,
Erich
