Problem with ant+ on Mac

Goodmorning everyone, I’m from Italy and new on the forum. I’ve a problem to connect my smart trainer zycle with my new macbook via ant+, i can use bluetooth for cadence and power integrated sensors, but i need ant+ for the control of rools resistance and heartrate. So i’ve an ant+ dongle recognized by my mac (i can see it on my mac system info), and during the devices pairing on zwift the ant+ symbol turn on, but it can’t find my trainer and connect with it. If i do the same operation with other windows 10 pc with the same dongle, it works immediately. Anyone knows possible solutions for this problem?
(P.S i’ve a 2020 Mac and i use a usb-c usb hub to connect my dongle)

Thanks a lot
