We don’t have a check box for the FTDI driver install on the Mac. Provide as much relevant information as possible when you reach out to support - at a minimum, mention the type of computer you’re using, the type of laser (or controller), and which version of the software you’re using.
MacOS ships with a driver that conflicts with the one used by the FTDI chip in the Ruida controller, and if they “fight over” who gets to talk to the port, it can get locked out. If that happens, the only way to release it is to reboot the computer.
We recommend using a wired Ethernet connection for MacOS - it doesn’t have the driver issue, and it’s twice as fast, and more robust. There are instructions for connecting that way here:
