Right now I have my laptop, which I connect to two external monitors. Ever since yosemite update, I can't seem to get my second monitor to work. The monitor that is connected via firewire works but the monitor that's connected via KWorld USB Adaptor does not work.
Help!
I will help you determine if your adapter is supported by your current version of OS X, update the driver if needed, and provide you with the resource to update the driver yourself in the future.
