[Qgis-user] R in QGIS on OSX using Kyngchaos build

[Pieter du Plooy]

Hi guys

Thanks for all the info on this.

I have reverted my one Mac to Mavericks, as I want to test the Horao plugin
on Mac, and Openscenegraph does not play nicely with El Cap and from what I
heard also Yosemite.

I'll leave El Cap on my other Mac, and see what this does.

SIP was disabled on this machine for Grass install, but I will do the
linking later and also test out your recommendations.

Pieter
