Hi torsten, that's a bummer that the 3d connexion install trashed your system, I'm really surprised about that. I guess there have been enough changes in Sierra that the old drivers will not work anymore.

I don't know why the newer drivers stopped working with MoI, I posted a question in the 3d connexion developers forum about it quite a while ago and received no response. I kind of suspect that they may not support 32-bit apps anymore though. I don't think there is much I can do about it until MoI v4.

Right now if you want to use a 3dconnexion device with the MoI Mac version it looks like you'll have to run an older OS than Sierra, until MoI v4 is out.
