Which voltage do I choose? The DSD TECH SH-U09C has a jumper to select 3.3 or 5 v. Does the device I'm connecting to determine this or is it the USB?

Select the voltage based on the device you are connecting and trying to communicate with. This selector either delivers the 5.0 V from the USB or steps the 5 V from usb down to 3.3 V depending on the voltage required from the microcontroller you connect to.

I cannot find the board on arduino on my macbook. although after intallation of the driver i can find it under utilities and usb, what should i do?

please refer to the following: You can verify that this adapter is working properly by: Short TX and RX. You will receive any data you send.
