I installed Assistant 2 on 2 different Macs and when I plug in the USB cable to the Mavic Air, nothing happens. Thanks for any assistance.

Hi there, thank you for reaching out. Regarding your concern may I ask are you able to notice the HoRNDIS drivers will install? and also before Installing the Software make sure to turn off first the Antivirus and firewall as well just to make sure the Drivers will install properly.
