Ethernet adapters conversion from MacBook Air (Mid 2012, 13") to MacBook Pro (Late 2019, 16") So I've just bought the latest MacBook Pro (late 2019, 16&quot;) and bumped into the common issue of not finding 1 piece of Ethernet adapter. I want to use only Apple made adapters, so I'm left with the option of buying Apple Thunderbolt 2 to Ethernet adapter AND the Apple Thunderbolt 2 to Thunderbolt 3 adapter and daisy chain them.
So, since I've been using MacBook Air (mid 2012, 13&quot;), I already own an Ethernet to Thunderbolt adapter (Apple made).
The only thing that I'm still not certain about is - does the adapter I already have use Thunderbolt 1 or Thunderbolt 2?
According to Apple's spec, MacBook Air (mid 2012, 13&quot;) has Thunderbolt 1, but I have a feeling it's actually Thunderbolt 2, because when I look at system's preference, I see that the thunderbolt connection throughput is 10GB/s * 2 (written exactly like that - * 2!) So.. 10*2 is 20, and 20GB/s is equivalent to Thunderbolt 2, right?
I also tried to read the specs of the Ethernet to TB adapter I have, but it doesn't mention which TB it is!
Bottom line: can I simply purchase the TB2 to TB3 adapter and chain it to the current Ethernet to TBx (x=1/2, I don't know!) I already have?
Thanks!
The Belkin USB-C to gigabit adapter that Apple sells online is the best bet for you.

Much better than chaining Apple gear in performance, reliability, price and power usage. The Apple thunderbolt 2 model works fine with the Apple adapter - just you have overkill and two joints to manage.
