thanks, any clues of why?
Some lyrics from Kenny Rogers’
The Gambler are helpful in answering this question. Specifically:
You've got to know when to hold 'em
Know when to fold 'em
Know when to walk away
And know when to run
Some problems we can address or try addressing. Other problems are much more complex and previous efforts to solve them have been unsuccessful. With Hackintosh we don’t have the source code, we don’t have hardware developer kits, we don’t even have formal spec documents for protocols such as Thunderbolt, we have almost nothing to work with as compared to the Apple engineering teams. To us, most things are black boxes and many of our successes in the past have come from trial and error.
When it comes to Thunderbolt compatibility, either a device works or it does not. This is a class of problem where we must be willing to walk away from an incompatible device.
If you do not need the controller to be flashed, try restoring the original firmware.
