Hi @brecht, I’ve had a user of our addon point out that on MacOS there appears to be a problem importing any addons, including ours. I can successfully run 2.80.74 (build hash - bbb3500c9716). But when I run the RC ( which I noticed has been released as a .dmg) version, I get this when I attempt to run blender with certain addons (including our Crowdrender addon) enabled.

It seems multiple addons are affected as well, from a cursory inspection, any addon that uses ctypes seems to be affected. I’ve verified this by running the following command in the blender 2.8 RC’s scripting environment;
import ctypes
Traceback (most recent call last):
File "<blender_console>", line 1, in <module>
File "/Applications/Blender.app/Contents/Resources/2.80/python/lib/python3.7/ctypes/__init__.py", line 543, in <module>

Finally there is a workaround that the user who reported this has discovered for MacOs, but it appears to involve disabling the system integrity protection which I don’t fully understand the consequences of and am hesitant to recommend as a long term solution.
Bottom line is we think there is a bug. Addons, including ours were fine in the bbb3500c9716 build, the release candidate can’t run certain addons now and can’t import ctypes. Should I go ahead and write a bug report?
