IFCPlugin.plugin

IFCPlugin is a system-level internet plug-in component for macOS, not a standalone application, so it cannot be updated through the App Store or a standard software download. The correct update path depends on how the plug-in was originally installed. If it came with a third-party BIM or CAD application (such as ArchiCAD, Revit, Vectorworks, or similar), check that application's built-in updater or the vendor's website for a new version. If it was installed as part of a macOS system extension, reinstall the parent application or contact the vendor (Ifcpluginlib) directly to ask whether a native Apple Silicon build of the plug-in is available. Given that there are no recent public updates from the vendor and macOS has gradually deprecated internet plug-ins (moving most functionality to web standards and browser extensions), it is worth confirming with the vendor whether this plug-in is still actively maintained and whether a modern, native Apple Silicon alternative exists. If you rely on IFC viewing, also check whether your primary BIM software (such as ArchiCAD, Revit, or Trimble SketchUp) ships a native build — many have added built-in IFC support, making a separate plug-in unnecessary.
