[Solved] Renders forever on macOS blender

Just installed the BlendLuxCore-v2.1alpha4-mac64-opencl.zip on macOS 10.13.6 in blender 2.79b...

When I try to render just a simple cube with matte material I see the GPU usage goes up to maximum...and seems the rendering never ends...
the render progress shows always 0% even after 10 minutes...

On Debian 9 the add-on couldn't be even activated...
Traceback (most recent call last):
File "/usr/share/blender/scripts/modules/addon_utils.py", line 331, in enable
mod = __import__(module_name)
File "/home/user/.config/blender/2.79/scripts/addons/BlendLuxCore/__init__.py", line 13, in <module>
from .bin import pyluxcore
ImportError: /home/user/.config/blender/2.79/scripts/addons/BlendLuxCore/bin/libembree.so.2: undefined symbol: _ZN3tbb10interface78internal15task_arena_base24internal_max_concurrencyEPKNS0_10task_arenaE

This is the normal behaviour.
You can cancel the rendering when you think it's noise-free enough.

However, you can also specify halt conditions, e.g. a samplecount, time or noise-level.
