I tested with the new version: www.indilib.org/jdownloads/kstars/beta/kstars-3.6.3.dmg Same behaviour persists. For profile excluding EFW the editing of train works well but camera exposure hangs after started For profile including EFW Indi drivers start up excl. EFW but no tabs visible in Ekos. I attach the log file of the test run.
