IMHO you shouldn't be able to route the traffic of your Mac to a VM (Host-only Adapters) on this Mac, which relies on this Mac to route (NAT-Adapter) the whole traffic to the internet.
Solutions
- Set up a MacOS X VM with the Android SDK (probably), configure a Host-only Adapter and use the Tapioca VM as proxy/router for the MacOS X VM
- Set up a 2nd Mac and install mitmproxy and configure your main Mac to use the 2nd Mac as proxy/router
