I am attempting to install the Oscurart tools as found in https://github.com/oscurart/BlenderAddons. I tried other sources first but no luck with them either.
I have Blender 2.76 2015-Nov-04 on a Mac running 10.11.3
After downloading the zip file from GitHub I used install from file in the Add-ons pane of Blender's User Preferences to install the zip file. I don't get any notifications from Blender that I see as to a result but it goes back to the Add-ons list.
The files do all appear in ~/Library/Application Support/Blender/2.76/scripts/addons.
Quitting Blender and restarting it even with all three support levels selected and All categories the tools are no where to be found. I've looked at all the other answers related to installing addons I can find and have come up empty.
Does anyone have any clue what is going wrong?
