2016 13" MacBook Pro [6th,2C,U] + RX 480 @ 32Gbps-TB3 (AKiTiO Node) + macOS 10.12.4 & Win10 [jefniro]
I discovered only one problem now, if I boot Windows from my internal SSD (no external USB key) with Akitio Node attached, Windows hangs after few seconds, with the Windows logo. If I boot without Akitio Node attached, Windows boots normally... I need to investigate with others tests...
Yes, this is normal. The USB key (apple_set_os.efi) is required on every boot to keep iGPU activated. To avoid complexity, Apple’s USB-C to USB adapter is recommended (no hubs). The Node must be connected to the second TB port on the left, closest to you.
Damn... followed your instructions, now my MacBookPro doesn't boot anymore from the external USB Key... :o(((
When I select the external EFI USB Key it starts with MacOS and not with Windows OS.
If I boot normally Windows OS it hangs at boot when Akitio is connected.
p.s. with Test mode off and dsdt deleted still error 12
"1. Open Startup Disk on macOS, choose BOOTCAMP partition and restart the Mac with the USB stick."
Should boot into Windows.
I tried again with the start manager trick, with TEST mode off and without dsdt table modified it doesn't work, even if I disable and then I enable the PCI bridge. It returns to me the 12 error always.. :o( (boot from external USB key)
