Axidraw arrived today.
I had an older version of inkdscape already on my MAC Book Pro (OSX 10.9.5), but used "AxiDraw_Mac_v122.dmg" to overwrite it.
Axidraw does not show up on the extensions menu.
Rebooted / reinstalled / re-read instructions
Looked for /Applications/Inkscape.app/Contents/Resources/share/inkscape/extensions/ , but it did not exist, so I created it manually, and moved the files from the zip file into it, and rebooted again.
The extensions menu still does not show axidraw.
Note also that the stuff that IS on the extensions menu is NOT in the directory with the axidraw extension files.
Can there be another one elsewhere? What am I not seeing?
