Unfortunately, the program that I wrote in Builder still does not work, and gives the same error message as before (‘Error starting ioHub server’, raised when the program reaches the line ‘io = launchHubServer(**iohubkwargs)’. The iohub pstbox demo program for Coder ( ) now runs on the Mac when I change the line ‘SERIAL_PORT = ‘COM4’ to ‘SERIAL_PORT = ‘\dev\tty.usbserial’. I hadn’t tried installing a driver on the Mac, as this hadn’t been necessary on a PC, but installing the driver that you recommended worked! The device now comes up when I type ‘ls \dev\tty*’ in the Terminal, and is listed as tty.usbserial.
#Look for usb prolific mac mac os#
I also tried plugging and unplugging a USB flash drive to see whether this would make a difference to the list of /dev/tty entries, and it failed to do so, despite the fact that the Mac was able to view the contents of the flash drive when it was plugged in.ĭoes this make any sense to you? By the way, the Mac OS is v10.13.3, not v10.16 as I said previously. I know that the adapter is being detected and recognised by the Mac, because it shows up in About this Mac > System Report > USB with the correct product details and a location ID that is specific to the USB port used (e.g. I opened the terminal window and typed ‘ls /dev/ ’ and this brought up a lot of /dev/tty entries, but the list of entries did not change when I plugged and unplugged the USB-to-serial adapter, re-typing ‘ls /dev/’ each time. Unfortunately, I’ve been unable to identify the name of the port. I’ve only just had a chance to follow your advice, because of the Easter holiday period.
