Unfortunately on a Mac, the EC135 is no longer functional for me, neither alpha nor beta.
I've tried trashing main.mcf but still the impressive 3d Stop sign. The R22 works very nicely though.
The trouble seems to begin here:
1.71-tmmodelmanager: loading dynamics begin 'ec135'...
1.73-tmfile_properties: WARNING: property 'EventModeSwitchedOffLateral' is not a member of type 'mode_annunciator_ec135' hash=11805263664507508915.

With me it works without problems.
