the normal for mac:library/application support/sketchup2013/plugins/
Everything else works. And Dave R apparently encountered the same thing...I got rid temporarily of other plugins to make sure they do not affect that one. No change.

I am attaching a new screen shot - got rid of all plugins but native sketch up and bezier. Still Crashes!

You are right. I moved it. Bezier lasted this time for maybe 8 curves, then bugsplat:(((

library and all that - downloaded from the store, so all new...Tried to delete and reinstall - the same thing.Without changing tools, just a few curves on a blank file, sometimes less than a complete curve - bugsplat. I am attaching a screen shot of plug ins - maybe you see something that I do not. Permissions are all the same for other plugins,including Fredos, so should not be an issue. His other plugins work just fine, no crashes.

Was there a solution? I have the same problem, Mac 2013pro, permissions, etc, reloaded - still crashes....The only plug in that does...Fredo6's loft tools do not, so I have an updated library, etc

Is anybody using this plug in on Mac Sketch Up Pro2013? My plugin crashes after a few seconds....

Superellipsoid Plugin

Version: Superellipsoid 1.0
Release Date: July 1, 2010
Requirements: SketchUp 6.0+
I have it as a tool under "draw". The form comes in as a component. When I try to use a section cutface, it crashes the Sketch up. Tried to use sectioncutface with other solid forms and it's fine. It's really not that crucial:)))
Thank you for all your plugins.

Actually I was using it on superellipsoid plug in...Have to investigate more with other shapes/versions. I was thinking myself that it's a conflict between plug-ins...

Crashes consistently with Sketch Up Pro 2013. worked for Sketch UP 8. Anybody has the same problem?
