I am using a mac and trying to root my bionic. I have rooted by Droid X in the past, so not totally foreign to the process. Seem to have the correct file to load, USB debugging turned on, tried both "Charge Only" and "PC mode." Continues to not find my device. Any ideas???? This is starting to make me a bit crazy. Someone suggested a factory reset in another post. I will try that, but if anyone has other ideas, please send them my way
