micro_ros_setup No definition of [python3-vcstool] for OS [osx]

edit

I'm tying to install a micro-ROS development on my Macbook (Big sur 11.4) and have run into issues after the following steps:

Update dependencies using rosdep sudo rosdep update rosdep install --from-path src --ignore-src -y

I end up with the error:

ERROR: the following packages/stacks could not have their rosdep keys resolved to system dependencies: micro_ros_setup: No definition of [python3-vcstool] for OS [osx]

My python version is Python 3.9.6. ROS2 version is Foxy Can anyone help with this issue?
