There are some old posts with this question. While it would be better to just switch to windows, you’re on Mac. I recommend looking up the old posts because some of them found solutions from moderators
Honestly, not much you can do. I started out using Mac, but I couldn’t get it to work, so I switched to Windows. You could always try downloading a Virtual Machine to run Windows software on your Mac, but unless you have some tech know-how, I wouldn’t recommend it. As Emerald said, your best hope may be to see if someone else ran into a similar problem and asked about it.
This one is better as it was solved by the moderators. Help w Mac download
