I'm having trouble finding the extensions folder for on a mac so that I can install this extension: http://www.bobcookdev.com/inkscape/inkscape-dxf.html and get the dxf r12 format instead of the dxf r14 format because it sounds like openscad might be able to handle that better than the r14. But none of the instructions for installing extensions using the mac version have been clear. So I would very much appreciate any steps that someone might be able to offer!

Hi.

Have a look at this thread; http://www.inkscapeforum.com/viewtopic.php?f=5&t=7463

By the way the problem is not the DXF file you are trying to import into openSCAD.
See your other thread on the subject.

Those instructions aren't working for me. I didn't have an extensions file, and I created it manually, but the save option isn't showing up.

Here's the folder structure: http://screencast.com/t/tlSNDszD Does that look right?

No, and it won't work this way (unless you have outdated 0.48.5 installed - which would have had the 'extensions' folder in this location anyway). The internal bundle structure changed in Inkscape 0.91 for OS X (see Inkscape menu 'Edit > Preferences > System' for current paths). Note though that the recommend way for users to install custom extensions is to install them into the user inkscape profile (this works on any platform Inkscape supports).

On OS X, the user inkscape profile is at the same location as on linux: Install custom extensions into
To access hidden folders (folders with a filename which starts with a dot aka period) on OS X, either use the Terminal, or - for the Finder - use 'Go > Go to Folder ...'.
