    Does anybody know where in this case the install file is stored when you install it? At least not in Applications folder.

    Sure wish they had done this back in 2014 since I plugged a USB bar that screwed my USB port on the MBP and now all I can do is run the USB bar everywhere I go to use anything that is USB. I can not use a single peripheral in the port.
