Apologies for the delayed response.
The adapters are designed to use the Thunerbolt 3 devices in Thunderbolt 2 ports but it should work the other way round as well.
In order to isolate the issue , can you try connecting your Pegasus 2 R4 with any MAC computer with thunderbolt 2 port (If possible) ? . If that works then we can confirm that the Pegasus is good.
If it is not possible , please open a case at https://support.promise.com with the MAC system report to troubleshoot the issue.
You can also conatact us at 408-228-1500 for immediate response.
