That’s good to know! Very soon this will become a huge issue for us. Out of necessity we're converting over our older 10.8 systems to newer Apple hardware that runs only 10.10+. There’s no way to “replug” a USB device within a sealed kiosk system, so we’ll be needing either an outright fix or a some kind of workaround that can be run after boot (such as a manual bus rescan). -Carl _______________________________________________ Do not post admin requests to the list.
