Wondering if anyone had any advice. Also the only port, serial or otherwise on my mac is a Bluetooth one. Should I use a different computer or is there another solution.
BTW this is a school macbook that I don't have admin access too, I could get the passcode if it is needed, school keeps all passwords on local server accessible with a LAN to USB cable. I have an iMac that I own with no admin restrictions if I need to swap to that.
Anything helps, thanks.
