Although it would seem pretty straightforward, Apple has posted a frequently asked questions page for its new Thunderbolt to Gigabit Ethernet Adapter, which answers any burning questions you might have about the $29 dongle.
Apple has updated its support website with a new Apple Thunderbolt to Gigabit Ethernet Adapter: Frequently Asked Questions entry, posing six questions that users might ask about the $29 dongle, along with comforting answers and resolutions to any potential issues.
Such as: Yes, you can use the adapter with any Thunderbolt-equipped Mac running OS X Lion 10.7.4 or later, but you’ll want to install the Thunderbolt Software Update 1.2.1 if your Mac was released prior to this month.
Yes, you can connect the adapter to any Thunderbolt port, including the pass-through port on an Apple Thunderbolt Display or third-party device. However, take note that other devices in the chain could adversely affect performance.
“Mass Storage and other high-bandwidth devices can affect the performance of this adapter,” the FAQ notes. “If you have issues mixing this adapter with such devices, connect it directly to another Thunderbolt port on your computer, or connect it to a low-bandwidth device on the Thunderbolt chain.”
That is, unless you only have one Thunderbolt port, in which case you’re pretty much up the creek without a paddle, as the saying goes.
One last tip: No, the Thunderbolt to Gigabit Ethernet Adapter can’t be used on a Mac without Thunderbolt, even if you’re able to plug it into that old Mini DisplayPort jack. But you already knew that, didn’t you…?
