So I'm a very early beginner (I started messing around with my new uno only about an hour ago) and I was going through the steps in the Mac Osx beginner guide. I got to the last step (testing the sample code) and neither the tx or rx LEDs lit up. I realize now that the guide is probably a bit out of date, the code was working fine but lighting up L instead of TX or RX. So, me being the beginner (idiot) that I am I try to figure out what I did wrong. I thought that maybe I chose the wrong port (even though I disconnected and reconnected the UNO to be sure when I first set it up). I thought I might as well try a different port and selected the other dev usbmodem port. The instant I uploaded the program my screen went black and I'm only getting a blank white screen on restart. Please help.

Have you unplugged it?

Try restarting the Mac in safe mode (hold down Shift after you hear the startup tone).
Please post technical questions on the forum, not by personal message. Thanks!
