Hello, I too have a MacBook and was successful in following the guidance provided by SnappleofDiscord. (See link below) It takes patience but just keep poking around and playing with it - you can’t harm your CD and it’s even easier if you download everything to your laptop and work from there. Also, if you put “3D slicer” into the search box on this amazing site you will see other helpful advice.

Good luck with everything.
