I am trying to use the XYtools plugin for QGIS (*because copy-paste is not working with just one of my files?!*), and I'm concerned that I actually just need to update my Python but not sure if doing so would disrupt anything. I've read all the posts on 

> install python xlw and xlrd libraries

errors, but most instructions seem to be for PC or assume Python version >= 2.7.

I installed QGIS about 4 months ago on a brand new machine running Yosimite, using the `QGIS 2.12 built for Mac OS X Mountain Lion, Mavericks, Yosemite and El Capitan. Built with Qt Cocoa 4.8.` The only `Python` I can find on my machine is version 2.6. 

*update: In the meantime, I installed the Quick Export plugin and this gives me (almost) what I need. The strange thing is, even this appears to leave out several (seemingly) random entries in the table. I'm not entirely positive there isn't a problem with the project, as I have no problem copy-pasting from other projects. In any case, the question still stands (potentially for other plugins).
