I posted a message one hour ago, but I have learned that the sectioncutface.rb does work with mac. Needed to make the folder Plugin in my libary. Thanks for the solution to a big problem.

I've only been using SU for half a year and I love it. But at the same time leaving autodesk for sketchup, I left pc for mac and I allso love that. Just one tiny little problem "sectioncutface"!!! Everyone gets saved by Tig, but what about me and my resentance to ever using pc again. Is there anything simular to OS x?! Help http://forums.sketchucation.com/posting.php?mode=reply&f=323&t=20564#
