I used to use the HandsFree 2 app. It worked perfectly and it even recorded calls, incredibly useful. But now in Catalina it crashes and it seems is discontinued.
What it did, which would be perfect to have again, is to couple with my smartphone (Android) via Bluetooth. When someone calls, the computer would show a notification and allow me to deny or answer within Mac. Answering the call is like speaking on Skype (earbuds optional). I could also make a call from the app, which would show my contacts but I could also dial a number and same thing.
I have been scouring for an alternative and have tried a couple (PhoneCall comes to mind), but none of them worked. I'm using an Android phone with modern Bluetooth support and MBP 16" with Catalina 10.15.3.
What options do I have?
