As in the Gimp post, all these things also work in Linux and Windows so maybe you should give a try to these kind of hacks! 🙂 There’s no too much tweaks needed for Inkscape but at least we can get almost the same look and feel of gimp - a dark and tiny theme which is Very Fine and don’t make you feel uncomfortable to use it on OSX. The main issue with Inkscape is the ugly theme that came by default.
