I have installed VarAC and VARA HF modem on my MAC. It looked like it was running fine; I can send beacons and broadcast and see stations calling. The only problem: once I am connected, or someone connects to me, the system crashes when I try to send a message. From the log it looks like there is a problem connecting via KISS to the VARA modem. I already tried to change the KISS port, same problem. Firewall is off. I am using VarAC V 6.4.15 with VARA HF v4.7.2 on Crossover 22.0.1 on a MacBook Air M2.
