My Eclipse plug-in adds a category in the File - New - Other... dialog and provides a wizard for adding new projects. It is developed on MacOS 11.1, JDK 15.01, Eclipse 2020-09, and runs in the debugger without problems. The plug-in does only depend on standard plugins:
Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: wim.ix Plugin
Bundle-SymbolicName: de.wim.ix.dev.eclipse.plugin;singleton:=true
Bundle-Version: 20.0.1.14

lib/commons-compress-1.20.jar,
lib/gson-2.8.6.jar
Bundle-Vendor: wim.ix
and all further required jars are included in the plugin-jar.
I follow this tutorial, 20ff, to create an update site from where the plug-in (resp. feature) can be installed.
On Windows and Linux with the same JDK an Eclipse versions, the installation works fine. The category in File - New - Other... is shown and the wizard dialog can be started.
Installing the feature into the Eclipse on MacOS - where it has been built and debugged before - does not show an error too. Howerver, the category does not appear in the File - New - Other... window. The feature is listed in Eclipse - About - Installation Details... as installed software but is not found as installed plugin.
If the plugin is copied into the Eclipse/dropins folder, the result is very similar: It works on Windows and Linux. It does not work on MacOS.
Is there anything special to do on MacOS for importing a feature/plugin?
