I have a issue with the new HP spectre x360 and new Thunderbolt Drivers, I'm not able to change the security level of the Thunderbolt device and as I have seen, by default only Windows-certified devices are able to be connected to the computer.
I have an Apple Cinema DIsplay with a Thunderbolt 3 to Thunderbolt 2 adapter. This one work very well with my company computer ,an Elitebook HSN-104C.
When comming the time to change my MacBook pro and as the Elitebook works very with my Apple Display I have chosen to get a new HP for my daily driver.
I have seen on the forum that this issue could be solved with a Thunderbolt firmware utility to change de default behavior to accept all Thunderbolt device but I'm not able to find it for my new computer.
The Spectre has a Thunderbolt Controller 8A17 with the Intel Controller 22.214.171.124
The Elitbook has a Thunderbolt Controller 15D9 with the Intel software ver 126.96.36.1990
Already tested :
I have tried to update the bios -> Nop.
I have tried to use the Intel Software ver 188.8.131.520 -> Dosent's seen thunderbolt controller
Check into the Bios Settings to change Thunderbolt security level -> Not present.
For reference a post that solve the issue on others Spectre devices and Thunderbolt Display :

Have a nice day
