Today I learned that when you install jbdevstudio together with bundled eap, you should not get a popup from runtime detection when you start jbds. The bundled eap should be added silently.

This doesn't work on Mac. This is most probably because there is a different directory structure on mac.
See here:

./runtimes
./runtimes/jboss-eap
./studio/jbdevstudio.app
./studio/jbdevstudio.app/Contents
./studio/jbdevstudio.app/Contents/Eclipse
./studio/jbdevstudio.app/Contents/Eclipse/plugins
./studio/jbdevstudio.app/Contents/MacOS
./studio/jbdevstudio.app/Contents/MacOS/jbdevstudio
./studio/jbdevstudio.app/Contents/Eclipse/configuration/
