You can confirm the firmware version at the
bottom of the Device tab (Figure D-5).
Why does the firmware update require a
network cable?
Firmware updating was designed to use Ethernet
Settings mostly for convenience. If you have lots of
networked devices, you can upgrade them all from
a distance (even over Wi-Fi) without having to plug
in directly and without having to download or run
an updater application.
This approach was also taken for engineering
reasons, with reliability foremost in mind. When
installing an update, the device reboots into a
stripped-down recovery partition to guarantee
that the update process can always be completed,
even if the power goes out mid-update. Since
updates can also affect the Thunderbolt or USB
chips, they cannot be used during the update.
