I just don't get how they can miss this 2 betas in a row. Not only that but how in the heck to you go from a working system to breaking usb ports inside of what is supposed to be bug fixes? I'm also pretty sure that Apple is blissfully unaware that any of us are having sketchy usb issues on certain macs regardless of the feedback button. (cue the "beta police")and i thought that was only me. i have noticed strangely enough that at midnight i get all notifications including my drive was disconnected no properly..
