Rhino Datasmith Exporter installation issue

I’ve recently downloaded the latest version of Twinmotion (2024.1) for intended use with Rhinoceros (Version 8 - 8.12.24282.07002, 2024-10-08). I’ve downloaded the Mac Datasmith Exporter for Rhino for use on Twinmotion 2024.1.
However, when I go forward through the sequence of the Datasmith zip folder, to the uncompressed Datasmith folder, and then to the DatasmithRhino8.macrhi file, I receive an error message from rhino. Rhino tells me “Error Installing Plugin - Could not read the installer file.”
I’ve searched high and low for a solution but I’m unable to resolve this. I’ve reinstalled Rhino, and tried other methods of troubleshooting without success though. Any assistance with this would be greatly appreciated.

macOS 15.1 Apple M2 Pro

I am having the same issue with Datasmith for Rhino 8. I am on macOS 15.0.1 M2 Max

Hello, I just figured out a way that worked for me. I renamed the file from .macrhi to .ZIP, then unzipped that file and the renamed the file .rhp to .macrhi, then copy and pasted that folder in the ~/Library/Application Support/McNeel/Rhinoceros/8.0/MacPlugIns, and it worked fine after I restarted rhino.
