Hi Joe,
Unfortionately there is still no conda version of orekit, this is on my to-investigate-list but it seems from my initial tests quite complex and I don’t have a mac to test with so every iteration takes about 20 mins to build 
Some more on why this is complex is in the thread: Orekit Python Wrapper 11.3.2 released - #6 by petrus.hyvonen
What is doable as a fix meanwhile is to use the alternative wrapper based on jpype, it has been confirmed to work on mac platform: Files · master · Petrus Hyvönen / orekit_jpype · GitLab
