I can assure you that there are no plans to drop Mac support. 
I wish I could say we will have the updated app by a specific date, but that is just not possible; we have run into an internal issue with this issue but are actively working towards a solution.

Stay tuned!

We don't have this specific provider roadmapped, but I would recommend using an external IdP for authentication, then you can leverage any 2FA methods supported by the IdP.

OK, great! The fix for the issue is in the 23.2 version, so once you update try it again, but from what it sounds like, this is the exact use case we have tried to solve.

B-Rad,

What version of Control are you running, and is the client version the same as the server version?
