For the Mac you'll find out that some troubles with Plugins depends on what path you choose. If HD/...is not working, I always try out the users/...path which contains also a Sketchup folder.

i used to say this a lot around here but i haven't been posting in a while but.... πŸ˜„

sketchup actually does not have a plugin folder in the users/ path.. i challenge anyone to do a clean install of sketchup and find that folder.
installing podium puts the folder there and that's when things start getting screwy.
