Client has Enscape problem on Mac

Client sent me the following message:

SUPER URGENT ! Please Help !!!

I’ve uninstalled and reinstalled many times Rhino and Enscape. Still Enscape doesnt load ans message : Unknown Command

RHINO Version 8 (8.29.26063.11002, 2026-03-04)

Enscape-4.16.0.1262.dmg

Mac OS Tahoe Version 26.3 (25D125)

System.Exception: No PlugIn subclass found.

I don’t know anything about how plug-ins get installed and run on Mac… Anyone seen/experienced this and has a fix? TIA…

they need to contact enscape directly.
