I took all my instructions from this page. https://github.com/crr0004/deepracer
Here are the revised instructions for OSX (bold is console command)
- Change to a folder in terminal that is not case-sensitive. ~/ should be fine
- git clone --recurse-submodules https://github.com/crr0004/deepracer.git
- brew install minio/stable/minio -- you may need to install brew first -- /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
- install vncviewer from here https://www.realvnc.com/download/file/viewer.files/VNC-Viewer-6.19.325-MacOSX-x86_64.dmg
