Want to get gigabit wired speed from your MacBook? You can use a third party adapter with a funky third party driver (which, if you do any sort of research, are apparently all completely unreliable). Or you can use Apple 100mbit Fast Ethernet adapters. That’s right. 1/10th the speed of gigabit.
But a USB 3.0 adapter? Sorry, you can’t have that. Want a gigabit connection on your MacBook Pro? Better use the Thunderbolt Ethernet adapter. That wouldn’t be so bad, normally … Except you need those Thunderbolt ports to connect your monitors! Oh, and if you have a new MacBook 2015 and want a gigabit wired connection, you’re just completely out of luck.
By the way, Thunderbolt docks are egregiously expensive and notoriously unstable. USB 3.0 accessories, on the other hand, are very inexpensive. I’d gladly hang a USB 3.0 Ethernet adapter off a hub at my desk or bring one with me on the road. If I were allowed to.
USB 3.0 has been around for nearly five years now and drivers on Windows have existed for nearly as long. Is it really too much to ask for a USB 3.0 gigabit adapter for the Mac?
