My 27in Apple Thunderbolt display is not working with this product. Is the problem caused by my computer?

We've identified some compatibility issues with the 27in Apple Thunderbolt display (model: A1407) and our TBT3TBTADAP when used with certain Thunderbolt 3-enabled computers.  As a result, the display will not be detected and no video signal can be seen.

We've started to compile a list of compatible and incompatible computers.  The lists below are a work in progress and aren't comprehensive.  If you'd like to report an incompatible computer, please contact our technical support team to confirm the problem and we'll log the computer model afterward.

Note: TBT3TBTADAP is not compatible with Thunderbolt 4 computers so those systems will be omitted from the list of incompatible computers.
