My configuration:
MacBook Pro 13" touchbar, i5 2,9Ghz, 8GB RAM, 512GB SSD, Iris 550
Thunder3 modded + bequiet! 750W ATX modular PSU + Nvidia GTX 780 Ti 3GB connected to LG Ultrawide 4K display
Hardware Installation
1. Opened Thunder3 classic (i will need some time to build an enclosure)
2. Put GTX 780 Ti 3GB
3. Connected Thunder3 to bequiet! 750W Powezone ATX PSU which power both GTX 780 Ti (6+8-pin PCie) and Akitio Thunder3 (barrel plug mod from molex)
4. Connect to Mac
macOS configuration
1. Disabled SIP with csrutil from Recovery terminal
2. Downloaded TB3 enabler to let MacBook Pro use Thunder3 (sadly if you don't want to edit kext there is no way yet since Apple software blocked older Thunderbolt 3 devices)
3. Run new automate-GPU script

Does it work with Apple’s built-in Nvidia drivers?
1) sudo ./automate-eGPU.sh -uninstall
2) Restart
3) sudo ./automate-eGPU.sh -skip-web-driver
4) Restart
Just in case… what happens if you uninstall the TB3 enabler, and reboot into macOS by holding the Option key down? My Devil Box has the same TPS65982 chip and it reports “Unsupported” under the Thunderbolt bus. However, the TB3 enabler/binary hack is not necessary.

ah ah ah guys i will update thread tomorrow. Pictures when i find a way to organize this mess 😛
My first try was with Apple build-in drivers but i got no luck, in profiles it was detect as generic Nvidia card.
Do you mean i can remove TB3-enabler after first installation? Why holding Option?

Okay, so the latest natively supported Kepler card is GTX 780 SC 6 GB (GK110B chip).
Because of the older TI82 PD controller - it does not support hot-plugging on macOS so booting from the cold power state, and holding down the Option key may initialize TB3 handshaking without the binary hack, as with the TI82 equipped Devil Box (DSL 6540). What’s your Thunder3 firmware version? Even though we have the same PD and TB3 controller, the older firmware (17.17) possibly explains why the Devil Box doesn’t need the hack.
Another approach is to skip DetectGPU function:

Need a hub or USB-C peripheral connected to another port. I have a power delivery hub, so when i'm at home i plug eGPU and this device.
@all
GTX 780 Ti consume a lot of power, i'm trying the same setup with GTX 980, because i had some kernel panics under heavy load with my PSU stopping and i think 780 Ti drains too much power.
