Thanks so much for this guide, it's really excellent work.
I have managed to get Thunderbolt working on my 9360 (i7 / 16gb / QHD / 512gb).
The steps I took were:
- Update to firmware 1.3.2
- Update Thunderbolt controller firmware (http://www.dell.com/support/home/us...-13-9360-laptop&languageCode=en&categoryId=CS)
- Select Thunderbolt security level 0 in BIOS
You will not be able to hot swap, but it's working well for me with external storage devices.
One problem I have is that it cannot seem to communicate with video devices (Blackmagic Mini Monitor and Mini Recorder tested and working in Windows) - not sure what that's about, but I hope to get to the bottom of it.
