I bought this brand new adapter quite a bit cheaper than other resellers and I am in doubt whether it's original or a Chinese copy:
Shouldn't the question be, does it work?
At the reverse of the Lan port has this:
Designed by Apple
in California
Model A1433 EMC 2590
Assembled in china
3 logos
fc ce(2 logos)
As the Retina Macbook Pro required an Apple Thunderbolt to Gigabit Ethernet Adapter, anyone know where to get it cheaper than the £25 in the Apple store?
Hmm… I read somewhere that a1433 2590 was gen 2 and not gen 1!! Most of the sellers don’t know if it’s gen 1 or 2. This is so confusing.. lol.
All of these adapters are Thunderbolt 1, if that's what you're asking. It's more than enough bandwidth to saturate the 1Gb ethernet connection.Hmm… I read somewhere that a1433 2590 was gen 2 and not gen 1!! Most of the sellers don’t know if it’s gen 1 or 2. This is so confusing.. lol.
Pretty sure the OP worked that one out back in 2014. 🤣If it works.... just use it.
Ya I know that gen1 or gen2 doesn’t matter for gigabit Ethernet. But it’s just when buying the adapter on eBay the seller doesn’t know if it’s gen1 or gen2. As I’m not sure if I’m paying 30$ for gen1 or gen2.All of these adapters are Thunderbolt 1, if that's what you're asking. It's more than enough bandwidth to saturate the 1Gb ethernet connection.
are you even sure there are different generations of this? All Thunderbolt to ethernet adapters that Apple sold, and sells, are Thunderbolt 1 only, but they all work fine with Thunderbolt 2, and with Thunderbolt 3 or 4 if you use the Thunderbolt 2 to 3 adapter.Ya I know that gen1 or gen2 doesn’t matter for gigabit Ethernet.

Apple does not, and has never, sold a Thunderbolt 2 gigabit Ethernet adapter. They still sell the same one today that they introduced years ago. Specs are on this page: https://www.apple.com/shop/product/MD463LL/A/thunderbolt-to-gigabit-ethernet-adapter. Again, there would be no advantage to make it Thunderbolt 2.Yes cos gen1 has 10 gb/s where as gen2 has 20gb/s transfer rate. What I am not sure of is are the model numbers different for both or apple just kept same model number for both, which would be stupid.
