TB2->TB3 adapters or dual hubs?

[wegster]

I'm not up for the latest MBP models but expect once they make a true Pro again including 32GB I may upgrade.
Meanwhile I could benefit from a pair of hubs for both home and work, and am considering a 4K or another UW QHD+ display. I don't buy new displays yearly so t would be along the lines of a 34-38" UW or 4K...possibly with TB3/usb-c inputs included.

Are there tb2->TB3 adapters that will work with degraded bandwidth and sans charging so I could, for example, pick up a pair of TB3 hubs and displays and use with my 2015 via TB2 for the time being?

Protocol should be backward compatible but it's a lot of $ without confirmation.

Try the official Apple TB3 <-> TB2 adaptor - it is bi-directional, but you'll need TB2 cable.

Wrong direction for tb2 cable. Want to go from mbp2015 tb2 to tb3/usb-c hub or display.

You still use your existing TB2 cable in those scenarios.

So just to be totally clear, this is expected to work then?

Thread got lost in all the 'new model lovin' threads.
Anyone know for certain?

I don't think anyone can definitively answer that, because there aren't any TB3 hubs/docks available today (to my knowledge) that actually work with the 2016+ MacBook Pros. See more here: https://forums.macrumors.com/thread...-early-thunderbolt-3-devices-updated.2012381/

Also, I think your DP1.3 Display scenario is a wildcard, especially because I doubt TB2 will support that at full 4K/5K resolutions, especially paired with your main display.

Oops - should not have read as DP1.3, good catch.

Either way, I guess the real Q is is TB3 truly backward compatible, including via Apple's 'bi-directional' cable through a hub... Mailed OWC but they seemed to have tier 1 non-technical support and got a more or less scripted response.

Anyone still have a TB2 model BUT also already bought a TB3 newer model + TB3 hub?

I don't think a real TB3 hub exists today.
