To make addons, you need a modeling program like Blender of Milkshape. Then you can use notepad or something to script the model to do stuff. END.
does notepad come for mac?
Secondly, you have a mac,(lol) I' pretty sure you cant do much with it.
Mac's can make add-ons just as easily as Windows...
There's also the fact that Mac's generally forget up packaging.
Trust me, no. Most to all of 3D modeling softwares were made for PC, so the Mac translations are terrible.
will AC3D work because i have mac
If you can't figure this out on your own you will never be able to do it.
