I successfully installed QGIS 2.0 on my macbook running OSX Mavericks, but when I attempt to open the program, I get the following message: "QGIS cannot be opened because of a problem. Check with the developer and make sure QGIS works with this version of OS X. You may need to reinstall the application. Be sure to install any available updates for the application and OS X."

As far as I can tell, everything is updated and I reinstalled QGIS twice with no luck.

  • You dylib error indicates you may have upgraded a Kyngchaos.com QGIS install and not upgraded its underlying GDAL and GSL frameworks. GDAL Complete framework must be the latest 1.10, and GSL helps with some aspects of the georeferencer plugin. Besides Python modules (psycopg, numpy), those are the only frameworks now required. (Btw, this is all in the Kyngchaos installs' READMEs.)

I've just set up QGIS 2.0 on Mavericks, rather than upgraded, but see no reason why the process would be any different.

KyngChaos maintains the Mac version of QGIS (linked to from the QGIS site in case you're worried).

You need FreeType for Matplotlib. Ensure you download and install that first: http://www.kyngchaos.com/software/frameworks

You can then download Matplotlib python module from from: http://www.kyngchaos.com/software/python

Let me know if that works or if you still receive errors.

  • Installing Matplotlib worked, thanks! Unfortunately, after installing QGIS 2.0, I get an error when trying to open the program (see my modified post above)

  • @user25471 - Try reinstalling the latest version of the GDAL framework from KyngChaos. Make sure you use version 1.10 (the present latest version). You may need to uninstall QGIS before updating the framework, then reinstalling it.

I've tried reinstalling Python numerous times

Why ?

Python is installed in Mac OS X (look my answers in QGIS Python version)

The only thing you need is, as radouxju says, to install the matplotlib version of KyngChaos or other version of matplotlib, as long as the name of the resulting folder is matplotlib in the site-packages of the Apple Python (in /Library/Python/2.7/site-packages, where numpy is installed: numpy-override folder)
