Lilipad Simple: Project Not Uploading

Hi!
I’m trying to upload an existing sketch onto the Lilipad but was not able to get it to upload. I am using a FTDI Basic but cannot seem to connect it to the right serial port (/dev/tty.usbserial###). I’ve tried installing the FTDIUSBSerialDriver and even tried installing a script to uninstall the Apple supplied driver.

Using: OSX 10.10.5

Please help, I’m just trying to get my little sister to appreciate STEM.

Thanks!
