Hi everyone! This morning i tried to update the rig manager to the last beta version release in order to have the access to the rig editor in my iMac, but I had OSX11, then I updated it to OSX12 Sierra. When i tried to open it this message appears "Internal Error" and for the extended message I have a screenshot for you. It's strange because some days ago I also updated the rig manager on my laptop with OSX12 and it worked perfectly and it's still working, so i don't what could be the problem.
I hope in your help and thanks again.
