I got the error when I clicked the update button. But when I option clicked on the version, which shows all available versions, and selected 7.9.1, it then updated successfully on a Time Capsule.I received the following error when I tried to update the firmware on my AirPort Extreme 802.11ac:
Can anyone tell me what "error -16" means?An error occurred while updating the firmware. -16
It seemed like the firmware updated successfully, and the error only occurred after the updater forced the AirPort to restart. My AirPort seem to be functioning, and it now has 7.9.1, but the error makes me wonder if everything is ok.
