To verify this, I was under the impression that 2011-2015 MBPs supported Thunderbolt daisy chaining when running OS X or Windows, but OS X did NOT support DisplayPort 1.2 daisy chaining, but running Windows via Bootcamp DOES support DP 1.2 chaining? (and that the problem was that there are limited TB/TB2 monitors capable of chaining [ex: the older Apple Thunderbolt Display] - as most monitors made for chaining use DP 1.2, which OS X has not supported?)
