Nope. It's not mountable as a volume in OS X.So what happened?
Android File Transfer doesn't recognize my One.
I tried hTc Sync Manager & AirDroid2, both didn't work for me either. ATF, seems to be the best but for some I can get it to work.
I remember with One X, it shows up in Finder and let's me select Drive or Charge only. Is there a way I can get that back (in settings)?
