[QUOTE="Csmac, post: 1752792, member: 273394"] If you get the latest driver from Prolific it works fine on my 2012 MBP with Sierra. I've been using it for at least 6 months. Not a glitch. Make sure it is the right one for the version of MacOS that you are using. I've also used their drivers for older OSx versions for years. Of course I'm not using if for a Cisco device, but to control a ham radio so you may have an issue there as well, but in any case you should see the driver loaded when doing what I say in the next paragraph. Look in /Volumes/Dev/ for cu.usbserial and tty.usbserial to see if the drivers load. ***NOTE: Before looking be sure to plug in the adapter or else the connections won't show. In the terminal type this: ls /Volumes/"Macintosh HD"/dev/*.usbserial (change Macintosh HD to what ever name you have for your HD). If the drivers have loaded you should get a listing like this: /Volumes/Macintosh HD/dev/cu.usbserial /Volumes/Macintosh HD/dev/tty.usbserial I see the adapter in Network connections, but that was put there years ago by an older version of the driver. I'm not sure newer versions show up there anymore. Cliff [/QUOTE]
