We can confirm from the schematics(MacBooks) that all Intel Macs with Core i Series(until 2019 model) is using the hardware PCIe bifurcation strap. Some of them were strapped to x16, or x8 x8, or x8 x4 x4 depending on what they had been designed for. The same strap also works for iMac series, so far we have tested it on 2009, 2010, 2011, 2013 iMac.
