Hi Tig, thanks for the answer.

I actually re-installed version 8, and the dedicated folder in the application support appeared again.
i installed the plugin store and auto installed all the stuff.
it works, finally.

Thanks a lot man, glad to have such a great community available...

hi guys,

i am a newcomer and i do have a problem with the round corner plug in. using a Mac, with Lion installed, i installed Sketchup 2013 and the two Rpund Corner files..
now, the programm do recognize the plugin, but when i open it, he tells me:

Module RoundCorner requires Sketchup version greater than 5.0.160.
Current version is 13.0.4123

but it's kind of illogical, because 13 IS greater than 5!

another strange thing: i don't have any Sketchup folder in my Apllication Support. that means that i actually don't know where the sketchup plugin folder is!

it was so simple to install sketchup on a windows, but i really want to use my MacPro in the future...

Any Ideas?
