Hi Jarrod - it could be the cable.

If you have USB-C, try using an adapter to micro USB. Try using a USB 
hub with a power supply. Make sure the power is plugged into the 
compuier. Disconnect all the other non-essential USB devices.

Check the load on the computer when you have trouble - and use lsusb - 
see if the device connection to the computer is acting funny.

I believe you can use "brew lsusb" to install it you don't have it 

If you can uninstall the RTL dongle, try uninstalling it and then 
re-installing it.
