I've been trying to buy some dongles for my new MBP 2017, but as I've been reading lots of reviews and product descriptions, it seems like some dongles that work with MBP 2016 does not with the 2017 version. What's going on?
Also any insight on why we can't daisy chain the dongles (e.g. Thunderbolt 3 -> Mini Displayport -> VGA/HDMI)? I have lots of Mini Displayport dongles I would still like to use.
For example look at the product description in these two links:
THUNDERBOLT 3 PORT COMPATIBLE with the reversible USB-C connecter that connects to new computers and tablets > with Thunderbolt 3 such as the 2016 MacBook Pro (NOT 2017 iMac or MacBook)
NOTICE: the firmware of our products is updating now, please don’t connect this product to iMac 2017 and > MacBook 2017. USB TYPE C to Mini DisplayPort (Mini DP, MDP) adapter connects a computer host with a USB > Type-C port to a monitor or projector with Mini DisplayPort input, ★NOTICE★: DO NOT connect adapter(like mini > dp to DVI adapter) from other brand to USB-C to mini displayport adapter for a second signal convert, we > can't guarantee it works well.
