ROS on Mac

I got ROS on mac by using RoboStack.

Something to be careful, need to build with this flag

• Was having this error Could NOT find Python3 (missing: Python3_NumPy_INCLUDE_DIRS NumPy) (found), which I solved from finding this: https://stackoverflow.com/questions/76938631/ros2-cross-compile-colcon-build-could-not-find-python3-missing-python3-numpy

Fix

colcon build --symlink-install  --packages-up-to <package_name> --cmake-args -DPython3_FIND_VIRTUALENV=ONLY

Also, for sourcing, instead of source install/setup.bash, I find myself using

source setup.bash
