I purchased for my Mac. I would like to download to my android and not sure if that is possible and if so, where do I do that? Thanks,
The Android version has been withdrawn and no longer available. No word on if there will be a replacement since it was written by a third party.
For Android, you could use GedstarPro (http://gedstarpro.com/). You have to convert your RM file to GEDCOM format before.
Mac software is the full genealogy program. Mobile software is only a gedcom viewer and not available for android and very old for iphone. Try the free currently updated ancestry mobile app for any of your ancestry trees. It is much better and allows editing.
I use Family Search on my Android.
