THUNDERBOLT 3 SUCCESS!! with GA-Z170X-UD5 TH STARTECH "Thunderbolt 3 to Thunderbolt adapter" and the Universal Audio APOLLO 8 - El Capitan 10.11.6 iMac 17,1
1) Booted into my windows 10 hard drive and updated bios to F5 at the time of this writing (if on OS X change Bios for Windows usage) and (see Tonymac for bios update guides).
2) Once in windows, I plugged in the Startech adapter and turned on the Apollo. Then i went to gigabyte site (Link Below) selected the "Download Type" dropdown and chose Driver. In choose OS, I chose mine which is windows 10 64bit (see screen shot for easier reference). I downloaded it and ran it.
3) Next I went to the dropdown again and downloaded the Utility and in OS type chose "ALL" (See screen shot for reference) the Utility actually gives you the instructions on the order to do it all for windows so follow it. After installing the utility I don't remember if I re started but I do remember I checked if it picked up my Apollo within Device manager and it did. (I left the Apollo ON just forgot to turn it off)

4) I then shutdown and REMOVED my windows hard drive (it was only used for thunderbolt driver and firmware update)
5) Next I rebooted and went into bios changed back my Bios settings for OS X Usage 10.11.6
6) Once in OSX I opened UAD meter control panel to see if the Apollo was picked up but it wasn't. (I left the window open, just forgot to close it)
7) Next, I turned on hidden files. I opened terminal (app, utility, terminal) and I pasted this command inside terminal
defaults write com.apple.Finder AppleShowAllFiles YES (then press ENTER) Next hold down Alt key Right click Finder Icon and click relaunch.
8) I went to GO -> Computer -> My hard drive -> System/Library/Extensions (I had to open all in new tab double click didn't work) looked for all kext that said AppleThunderbolt (made a back up folder on desktop just incase) and I deleted them all I rebooted into BIOS. (I didn’t close Apollo app)
9) Next go to:
Peripherals -> Intel(R) Thunderbolt ->
Intel Thunderbolt Technology =
Enabled
ThunderBolt Boot Support =
Disabled
Security Level =
Unique ID
Thunderbolt PCIe Cache-line Size =
Change to 128
Ignore Thunderbolt Option Rom =
Disabled
Thunderbolt SwSMI Delay =
Change to 10
TBT Device IO resource Support =
Enabled
Reserved Memory =
Medium
Reserved Mem per phd slot =

Reserved Poem per phi slot =

10) I rebooted with everything installed and turned ON including the UAD Meter Control Panel window which detects the Apollo it was open on desktop.
The system picked up the Apollo 8 instantly once rebooted (Not sure if leaving everything connected and running makes a difference it was just coincidently ON from prior attempts)
*NOTE - I lost audio drivers after I rebooted but simply ran multibeast and selected only my audio drivers rebooted again and I'm back in business!
Hope this helps you guys!!
