I'm using a Mac OS Sierra. I'm on Blender 2.8 and just installed 2.81 to see if it fixed the problem. I'm trying to install Animation Nodes, Luxrender, Appleseed. Non of them are installing on either version.
I go to Edit > Preferences select Addons, select install from file, click on the zip file and nothing happens, nothing shows up on the list. I followed a few suggestions I found in old articles here but non of them work. I even copied the unzipped files into the Scripts/Addons folder. Nothing is working. Is there some different way I'm supposed to install addons from files ?
